Procedure: Radiation safety
- an apparatus that produces ionising radiation when energised or that would, if assembled or repaired, be capable of producing ionising radiation when energised; or
- an apparatus that produces ionising radiation because it contains radioactive material; or
- an apparatus prescribed by the regulations that produces harmful non-ionizing radiation when energised.
- Occupational exposure (e.g. Ultra Violet light, Laboratory);
- Medical exposure (e.g. Computed Tomography (CT) scans, medicines); and
- Public (non-work related exposure).
- Possess, or have control of, the apparatus or material;
- Use or operate the apparatus, or use the material;
- storage of controlled apparatus and/or material; or
- Dispose of the apparatus or material.
- The University has developed this procedure to implement the Radiation policy and principles. This includes complying with legislation, licence conditions and relevant standards, thus reducing exposure and risks to health, safety and the environment. This procedure lays out a training framework to ensure personnel receive the appropriate training to perform their duties.
- The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has issued the University a Source Licence (S0027) and three Facilities Licences (F0073, F0074 and F0075) to hold ionising and non-ionising radiation apparatus and/ or material and conduct research and teaching. Refer to the Radiation Safety Policy for additional information.
- The University's Nuclear Safety Procedure addresses dealings regulated under the Nuclear Safeguards and Non-Proliferation (Safeguards) Act, 1987 (Cth).
- The University uses a risk-based approach to minimise risks when working with, storing, handling, transporting and disposing of radioactive materials and apparatus associated with the University's research and teaching.
- Managing radiation risk involves conducting an assessment to:
- establish the context associated with radiation use;
- identify the hazards;
- assess the risks associated with those hazards;
- control the risks; and
- review the process for effectiveness and compliance.
Establish the Context: Consider the scope and nature of work within the laboratory area when working with radioactive substances or apparatus.
Identify the Hazards: Hazard identification is covered in detail in the University’s safety courses.
Assess the risks associated with the hazards: Assess both real and potential exposures.
Review the process: Regular reviews are a requirement of the Regulations. Also, consider whether new processes and techniques are available. If an incident (or near miss) occurs, incorporate recommendations and improvements into the protocols.
- Radiation workers working with Non-Ionising Radiation should apply the Precautionary Principle. The Principle of Optimisation of Protection is used to minimise exposure and ensure legal dose limits are not exceeded.
- In order to ensure that the University’s obligations are met the Radiation safety policy and the Nuclear safety procedure state the responsibilities for people working with radiation apparatus and/ or materials. To ensure that personnel can meet these responsibilities, this procedure provide duties (listed below) that the relevant personnel should perform.
Supervisor and research leaders
- Supervisors and research leaders are accountable to the Dean/Director and have the following duties:
- document proposed radiation work and research;
- conduct only justified (shall be documented) research and dealings (i.e. there must be a net benefit to the researcher or the community, considering social, economic and other relevant factors);
- Work with the relevant RSO/LSO to develop, document and implement a plan to manage the safety of all aspects of the proposed activity (research and dealings).
- comply with the University’s ‘new work' approval process (refer to paragraph 25);
- conduct hazard assessments. Where there are high or extreme risks (after implementing controls), contact the relevant RSO/LSO before proceeding;
- ensure that hazards are effectively managed such that individual exposures are below ARPANSA exposure limits and kept to the lowest level achievable, consistent with best practice;
- ensure that all necessary training (records kept) and supervision is provided to all radiation workers;
- provide proper resources (e.g. work area, safety devices and personal protective equipment);
- communicate with, local RSO and LSO;
- report any incidents, exposures or hazards via the Workplace safety incident and hazard reporting tool; and
- report any Workplace Health and Safety (WHS) concerns or matters within their jurisdiction to the local RSO/ LSO.
- All radiation workers are required to meet the responsibilities stated in the Radiation safety policy and Nuclear Safety Procedure, in addition extra responsibilities are provided in this procedure (refer paragraph10-25) for specific cases as applicable. The following apply to all radiation workers:
- do not operate equipment or enter a facility if not authorised;
- ensure that training obligations are met before work commences;
- be familiar with emergency plans;
- comply with all relevant safe work procedures, operation restrictions & work practices;
- identify and raise (with supervisor, RSO/LSO or HSR) any concerns or changes that impact on workplace safety or the risk assessment; and
- ensure that equipment, safety controls and PPE are functional and not damaged.
Pregnant radiation workers
- Females working with radiation will notify their supervisor (or the RSO/ LSO or Work Environment Group) as soon as they suspect they are pregnant. Once the pregnancy is confirmed, the supervisor must actively seek to further control exposure and provide information to the radiation worker on the risks to the embryo or foetus when the parent is working with radiation. When a radiation worker is no longer able to continue working with radiation, the supervisor (in consultation with the RSO) should provide suitable alternative tasks.
- Where a pregnant radiation worker continues to work with ionising radiation, a more stringent dose limit must be applied to the embryo or foetus. ARPANSA requires the same level of protection as for the public (i.e. a dose of 1 mSv a year during pregnancy).
- These conditions also apply to breastfeeding radiation workers
- Radiation monitoring badges should be worn at the level of the waist for a pregnant radiation worker or the chest for a breast-feeding radiation worker. Refer to ARPANSA Radiation Protection Series - 1.
Workers with a medical condition or implants
- Workers with a medical condition or a medical implant that may be affected by exposure to radiation (e.g. a heart pacemaker in a magnetic field) should discuss this with their supervisor, the RSO or the Work Environment Group (WEG). Supervisors and managers of the local area should provide suitable alternative tasks where the worker is no longer able to work with radiation for health reasons. For further information, contact the WEG (firstname.lastname@example.org).
University workers at external organisations
- Workers planning to work with radiation at external organisations are to document the type of radiation they will be working with and have their ANU supervisor and relevant RSO/LSO approve the work.
- Where the external organisation provides the radiation monitoring, the RSO (in consultation with the WEG) must consider how to combine external results with the University dose results.
- University radiation workers must comply with the external organisation's induction and training requirements.
- Any personnel who have not met the requirements of a radiation worker shall be directly supervised by an appropriately trained and authorised University radiation worker at all times when dealing with a controlled apparatus or material.
Visiting radiation workers at the University
- All visiting radiation workers including honorary appointments, summer students and non-ANU contractors will work with an ANU supervisor while they are working on ANU projects, on ANU grounds or in ANU buildings. Before any work starts, the supervisor shall approve the work and work conditions.
- Workers will meet (or exceed) all the set University radiation standards. They need to be aware of:
- their roles and responsibilities and how they may influence safety;
- the University and local area standards for working with radiations; and
- issues relating to age, pregnancy and medical implants.
- Workers must meet the local RSO/ LSO and discuss the work with them.
- Any worker working in or visiting a radiation area must undertake the local area induction prior to commencing work.
When the duration of work at the ANU is expected to be:
Then the following is mandatory
More than 20 days
- Where there is potential for new radiation workers or visitors to receive a radiation dose the supervisor must ensure that a Personal Dose Monitoring Badge is issued after completion of the local area induction process.
Trade contractors, workshop and maintenance workers
- When seeking access to hazardous and restricted locations, trade contractors, workshop and maintenance workers (including equipment technicians) must:
- adhere to the Control of access to restricted locations procedure;
- obtain prior approval from the laboratory or area supervisor, or in their absence, the RSO/LSO; and
- in an emergency consult with RSO, Facility manager or head of the research group and gain approval for access if they need urgent access. This also applies to after-hours access.
Facilities & Services supervisors of trade contractors
- Facilities and Services supervisors must ensure that prior approval and access has been granted by the laboratory/ facility manager and RSO (or WHS officer) before allowing access to trade contractors.
New work approval
- The local RSO, LSO and WEG can help to decide which approval level is correct for any new work. Approval for new work involving radiation may occur through:
- Local area assessment; or
- Radiation Safety Advisory Group (RSAG) assessment; or
- ARPANSA approval; or
- The Australian Safeguards and Non Proliferation Office (ASNO) notification.
Local area assessment
- A local area assessment is suitable when a new activity/project is conducted using a radioactive isotope or controlled apparatus currently in use within the local area and arrangements are in place to correctly transfer expertise with the isotope, procedure or apparatus to the new work location. The material or apparatus must exist in the School's ARPANSA inventory.

- Store packages and containers to prevent physical damage, reduce the effects of the chemical properties, contain spills or leaks; and separate packages from incompatible materials (packages will not need to be opened once placed in the store).
- The RSO should assess and record minimum and maximum radiation dose rates at least annually.
Storage of radioactive substances
- All radioactive substances should be stored in appropriate storage containers. Radioactive substances should be stored separately from non-radioactive substances. The storage containers should be appropriately shielded and:
- made of compatible material;
- kept closed; and
- labelled clearly and appropriately with radioactive isotope information.
- Unsealed radioactive residues at tracer levels may be stored in glass vessels with correct polyethylene or rubber stoppers.
- Ionising radiation can induce decomposition of water, so vented containers may be needed to store aqueous radioactive solutions.
- Thermally unstable radioactive substances need particular care and are to be stored in vented containers.
- Storage containers for beta-emitting isotopes should be chosen to reduce bremsstrahlung radiation.
- During building renovations/ demolition, RSO or Facilities Manager should bring to contractor’s attention all controlled apparatus in their respective areas. Complete Controlled apparatus identification and local listing form <Link to be provided> prior to commencement of their work.
Labelling of storage containers and ionising apparatus
- All storage containers are required to have a label that correctly identifies the radioactive substance. The label shall contain the following information:
- name of radio nuclide;
- activity level/details;
- description of contents;
- physical form;
- chemical form;
- encapsulating material; and
- Chemical Management System barcode.
- Long-lived radioactive material that is no longer required needs special storage containers and labelling. Contact your RSO for further information.
- All radiation apparatus listed on the University ARPANSA inventory must be labelled.
Transporting radioactive material
Mode of transport
Supervisor/ lab leaders

RSOs and University WHS
Transfer of controlled material or controlled apparatus within the University
- Transfer within the University may only occur between areas covered by the ARPANSA licence and only with the approval of the RSOs in both the areas involved. RSOs are responsible for:
- notifying WEG of the transfer on the next ARPANSA quarterly report;
- updating the Source Inventory Workbook (SIWB) with the new location of the controlled material or controlled apparatus; and
- where control of the source is passed to another budget area, the prefix of the University identifier in the SIWB is to be changed to reflect that change of ownership.
Transfer of controlled material or controlled apparatus to another Commonwealth agency
- Transfer of controlled material or controlled apparatus may occur between the University and another licensed Commonwealth Agency. The RSO from the area transferring the material must complete a Transfer Notice within seven days of the transfer and send it to the CRSO who sends the form to WEG for submission to ARPANSA.
- For information on transferring nuclear material within the University or externally, contact the WEG at Whs@anu.edu.au.
Transfer to a Non-Commonwealth Agency and disposal of controlled material or controlled apparatus
- Licence holders shall receive prior approval from ARPANSA. Transfer of a controlled apparatus or controlled material listed in the SIWB to a non-Commonwealth agency is defined as “Disposal” and requires prior approval from ARPANSA. The RSO/ LSO from the area transferring the material must complete a disposal request form and send it to CRSO/ CLSO who sends the form to WEG for submission to ARPANSA.
- Licence holders must ensure that disposal of controlled material or apparatus follows:
- The National Directory for Radiation Protection (RPS 6);
- The Code of Practice for the Near-surface Disposal of Radioactive Waste in Australia (RHS 35); the
- Code of Practice for the Safe Transport of Radioactive Material (RPS C-2); and
- The Code of Practice for the Security of Radioactive Sources (RPS 11).
Disposal of radioactive waste
- Radioactive laboratory waste released under a Radiation licence issued by the ACT Radiation Council does not require written approval. Disposal must be done in accordance with the local area Radiation Waste Management Plan.
- The Radiation Waste Management plan shall be endorsed by the RSAG and lodged with the WEG. Transfer of low level radioactive waste from the University to an approved location shall be done in accordance with the local area transfer procedure contained in their Radiation Waste Management Plan. The local RSO shall be notified prior to any waste leaving and they shall ensure that the transfer is fully documented.
- Disposal of radioactive waste material usually involves one of the following:
- returning it to the manufacturer or supplier for processing;
- concentrating and containing it;
- storing the material and allowing it to decay; or
- diluting the material.
- Every effort is to be made to minimise the generation of hazardous and radioactive waste under the Hazardous waste management procedure. If an experiment is to produce radioactive waste, the experiment designer must consider how to dispose of any residue, contaminated equipment and waste at the design stage. A protocol or waste disposal route must be available (and approved by radiation safety advisory group) before the work can commence. The local RSO is able to assist.
- Details for disposing of radioactive waste are located in the Hazardous waste management procedure.
- For disposing of controlled material or apparatus contact local area RSO/ LSO.
- For disposing of nuclear material consult the Nuclear safety procedure and send the completed form to University ASNO Liaison Officer on firstname.lastname@example.org for approval.
Import of radiation sources
- Under the Customs (Prohibited Imports) Regulations 1956, a permit from ARPANSA is required for the import of radioactive substances into Australia. Refer to the Non-medical import permits page for more details.
- To apply for a non-medical import permit, complete the appropriate application form:
- Non-medical single shipment - Application for permission to import non-medical radioactive substances - Single shipment permit
- Non-medical 12 month permit - Application for permission to import non-medical radioactive substances - Twelve month permit
- Submit complete form with required documents to the local area RSO.
- Local area RSO will submit the form to WEG for submission to ARPANSA.
- WEG will notify the local area RSO after receiving ARPANSA decision.
Minimum age limits
- Persons under the age of 16 are not to work in a hazardous or restricted radiation controlled area unless directly supervised, and are not to be exposed to conditions where that person may be exposed to radiation exceeding the effective dose limit for members of the public.
- No one under the age of 18 years old is to work in a hazardous or restricted radiation controlled area unless directly supervised. Refer to the: Control of access to hazardous and restricted locations procedure.
Personal Ionising Radiation Monitoring
- As a minimum safety precaution, radiation workers must:
- wear issued radiation monitoring dosimeters during their radiation work; and
- maintain their monitoring dosimeters and keep them clean as advised in the manufacturer's guidelines.
- The following table applies to personal monitoring.
When a worker ...
Begins work with the University in a radiation department, or performs work involving radiation exposure
RSO, supervisor or monitoring agency may request cumulative radiation dose reports or incident reports from past employment or exposure.
Ends their employment with the University
They are entitled to request a copy of their cumulative dose report and their incident report.
- ARPANSA recommends that the annual dose received by radiation workers should not exceed 20 mSv, averaged over five consecutive years, with no more than 50 mSv in any one year. The following protocols in table 9 apply.
Where a worker's dose results ...
>80 µSv per month or >250 µSv in a reporting quarter, or >1000 µSv per year
Report the dose results using the University's notification system.
Approach recommended dose limits
Strictly monitor and review the radiation work to ensure the dose remains within set limits.
Area, zone and equipment monitoring
- The Work Environment Group can conducts personal and area monitoring to identify where dose exceeds worker dose constraints, or where changes have occurred. Documented (ionising and non-ionising) radiation monitoring results provide information that assists in creating actions that reduce the radiation dosage to personnel. This also includes regularly monitoring equipment for leaks or contamination that could lead to personal exposure.
- The release of radioactive material into the environment is strictly regulated and controlled. Refer Disposal of hazardous waste procedure for further information.
- Radon, a naturally occurring radioactive gas that originates from rock and concrete, permeates into buildings. When the ventilation is poor, radon levels may increase. The WEG can arrange radon monitoring of buildings on request. Consult your RSO or the WEG for further information.
Testing sealed sources
- The RSO should arrange for leak testing for each sealed sources or its housing whenever leakage is suspected. Testing results shall be kept in accordance with records management processes.
- Local areas shall maintain:
- RSO/ LSO contact details;

Reporting incidents involving controlled lasers and controlled non-ionising apparatus
- Reporting and investigating all incidents, significant exposures and dangerous occurrences helps the University avoid repeating incidents. The following table applies to reporting any incident controlled laser apparatus and controlled non-ionising apparatus
- Protection of the individual(s) takes priority over reporting Follow the Provision of First Aid services and Emergency response procedures first.
Immediately, report the incident to the area supervisor and local RSO. All laser incidents should be reported locally and investigated.
Report the Incident via the Workplace safety incident and hazard reporting tool as per the WHS Incident management procedure.
The (WEG) will report the incident to ARPANSA by phone as soon as soon as practical to-do so and with written notification within 24 hours if it is:
The WEG will report all incidents involving controlled lasers to ARPANSA according to the University’s licence requirements (Quarterly Report).
- The local LSO and the area supervisor will provide initial emergency assistance. Additional assistance in responding to the emergency may be needed from:
- The RSO;
- University Security;
- University Maintenance workers ;or
- Emergency Services personnel.
- All personnel involved with the operation and management of controlled lasers are to be appropriately trained, i.e. to a level commensurate with the risk and their role. Training requirements for this procedure are detailed in table 6.
Laser Safety Officers
- Local laser safety officers are appointed in areas where controlled lasers are housed or operated and are charged with the responsibility of ensuring compliance with the University policy and procedures.
- A coordinating laser safety officer may be appointed at a University level to provide local LSOs a path to raise complex approvals (see Tables 3, 4 & 5) and specialist advice to the RSAG.
- All LSOs shall be aware of their duties and be provided with training commensurate with those duties, see table 6.
Contingency plan for traumatic eye exposure
- Where class 3B and 4 lasers are being used laser radiation safety management plans are to include a contingency plan for actions to be taken if a traumatic eye injury occurs. Serious eye trauma has resulted in the casualty going into shock and in extreme cases death has occurred and thus should be treated as a medical emergency. All personnel involved are to be familiar with the plan.
Immediately, call ambulance, cover casualty’s eye and monitor/treat for shock
As soon as possible after casualty is stabilised, report the incident to the area supervisor and local LSO.
Report the Incident via the Workplace safety incident and hazard reporting tool as per the WHS Incident management procedure.
The (WEG) will report the incident to ARPANSA by phone as soon as practical to-do so and with written notification within 24 hours if it is notifiable.
- Once the medical emergency is dealt with the appropriate accident reporting procedure shall then be followed.
Laser accident/incident investigations
- Incidents involving lasers will be investigated in accordance with the WHS incident management procedure.
Laser Eye Testing
- Staff involved with class 3B or 4 lasers shall undergo an ophthalmic screening (prior to working with lasers) to assess the baseline condition of their eyes. Refer to the Health surveillance procedure for further information on the testing requirement.
- Routine ophthalmic examinations of employees working with laser equipment have no value as part of a health surveillance program (AS/NZS IEC 60825.14Safety of laser products, part 14: A User’s guide). So only medically advisable ophthalmic exams shall be carried out, e.g. in the case of an exposure above the Maximum Permissible Exposure (MPE) or a traumatic exposure.
- Routine eye tests e.g. visual acuity, amsler grid etc. may be carried out as part of ongoing eye health program, as a validation of controls or as a precursor to more invasive tests after a suspected exposure.
Pre-Work or pre-purchase planning for laser activities
- Only justified (documented) research or dealings with controlled lasers shall be conducted at the University. All laser activity shall be planned, managed and approved using the processes stated in tables 3, 4 or 5 of this document as appropriate. Laser activity proposal shall adhere strictly to the hierarchy of control, for example in general approval for an activity will not be given for use of a class 4 laser when a lower class could be used.
- Where practicable the approvals process detailed in tables 3, 4 or 5 shall be commenced and developed as much as possible prior to purchase. Prior to purchasing a laser the supervisor or worker responsible for the activity shall confirm compliance of the device with the appropriate product safety standard (AS/NZS IEC 60825.1 or equivalent). Compliance should be confirmed as soon as possible (as far as reasonably practicable) on delivery before acceptance (taking control of the laser) and upon acceptance entered into the ARPANSA Source Inventory Workbook.
- All lasers shall not be commissioned until approval for the activity is obtained and necessary documentation is complete.
Storage and transport of controlled lasers
- When controlled lasers are not being used they shall be stored in a decommissioned state, i.e. a state whereby they cannot be simply activated by a passer-by. For example in a secure room with the keys or power supply physically separated.
- Unless a controlled apparatus is transferred off the source licence, the licence holder is responsible for its safety at all times. Any time that a controlled laser is transported around or between facilities a locally recorded safety plan must be implemented and the location change recorded in the inventory workbook by WEG.
Short term variation to approved activities and maintenance
- Short term variations to activities that have not been foreseen in the original activity approval shall be separately approved by the local LSO or coordinating LSO as appropriate. Short term variations to activities shall be documented and approved using the new work approval process.
- Where possible, regular maintenance activities shall be considered in the overarching work approval detailed in tables 3, 4 and 5. Laser radiation safety management plans should be written in a way that foresees and accounts for maintenance activities and plausible events. However, where this has not occurred maintenance shall be approved through a short term variation.
General controls for all lasers
- All work procedures using lasers shall be planned, managed and conducted in a way that meets the requirements of this procedure and the requirements of AS/NZS IEC 60825.14 and the AS/NZS IEC 60825.1.
- In general, risks shall be managed in such a way that eyewear in not required. Where this is not achievable or additional redundancy is required laser protective eyewear may be prescribed. In these cases the supervisor shall consult with the appropriate LSO who shall determine the appropriate laser safety eyewear rating. The eyewear performance shall be specified to reduce the maximum reasonably foreseeable exposure to safe levels and shall consider eyewear resistance to damage and impacts to user comfort/vision. For more information refer to AS/ NZS 1337- Requirements for eye protectors against laser radiation.
- Where class 4 lasers are being used laser protective eyewear should not be considered in isolation of the skin hazard. In such cases it may be appropriate to consider face shields rather than glasses or goggles.
- Eyewear users shall check the condition of their eyewear before each use and store to prevent damage from scratching or contact with water or chemicals. Users should always read manufacturer’s instructions regarding the proper care and use of eyewear.
Safety Associated with Servicing of Lasers
- In addition to the following requirements, if servicing is not included in the overarching approved safety management plan it is to be formally approved as a short term variation to the approved activity, see above.
- Approved and properly trained personnel shall service laser systems in line with licence conditions. The supervisors and/or LSO must ensure that any person who repairs or maintains controlled apparatus has the appropriate qualification and training irrespective of being University staff or contractor.
- If University staff are to perform service, a written service procedure with safe practice information must be documented. All enclosures, interlocks, and safety devices (shutter, etc.) must be replaced and verified operational prior to returning the laser to service.
- The above requirements still apply to when servicing is conducted off site unless the controlled laser is transferred off the University source licence to another jurisdiction.
Disposal, transfer and destruction
- ARPANSA approval is required prior to disposal, transfer or destruction of controlled lasers. All such activities shall be carried out in accordance with the requirement of this procedure, see table 5.
- Laser pointers are a common tool for many lecturers to highlight or direct a person’s attention to a relevant location. A presentation laser pointer should be a class I or class II laser product and labelled as such. Class 3 (III) laser pointers are not suitable for presentations and their use is restricted. DO NOT purchase laser pointers overseas unless they are clearly labelled and meet the criteria.
- Handheld battery operated lasers that emit laser radiation in excess of 1mW are considered a prohibited weapon under the ACT Prohibited Weapons Act 1996 and require a police permit. Additionally a large percentage of “laser pointers” also exceed the ARPANS limit and are therefore for a controlled laser (s). The use without approval per this procedure is a breach of the University’s license conditions. These dangerous lasers should only be used by trained and aware staff with a legitimate reason.
- Ultraviolet (UV) radiation (wavelengths from 200 to 400 nm) may be produced by low pressure gas discharge lamps for germicidal control in biological safety cabinets, or UV curing, reaction vessels and in Trans illuminators. The Ultraviolet radiation supporting document outlines the precautions required while working with UV sources. Refer to ARPANSA UV radiation Basics, Radiation Protection Series 12: Occupational Exposure to Ultraviolet Radiation and AS 2243.5 Safety in laboratories -Non-ionising radiation - Electromagnetic, sound and ultrasound.
- Infra-Red (IR) radiation (wavelengths between 760 nm and 1 mm) may be produced by IR lamps or associated hot materials (such as furnaces). Refer to AS/ NZS IEC 62471- Photo biological safety of lamps and lamp systems
- Radio frequency (RF) is the portion of the electromagnetic spectrum with frequencies between 3 kHz and 300 GHz. Sources of RF include microwave ovens, induction heaters, plasma sources, and radio transmitters. Refer to ARPANSA RF radiation basics webpage and Radiation Protection Series 3- Radiation Protection for Maximum Exposure Levels to radiofrequency Fields- 3kHz to 300GHz.
- Visible light is the part of the electromagnetic spectrum between 400nm to about 760 nm. The maximum sensitivity of the human eye occurs at 555nm. Sunlight is the main source of visible light and eyes are at high risk of damage from non-ionising UV radiation.
Other non-ionising radiation
- For concerns about any non-ionising radiation contact the WEG (via email@example.com) for further information and assessment. Refer to ARPANSA and Electromagnetic spectrum.
