The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is a regulatory agency under the Commonwealth of Australia that aims to protect Australian citizens from both ionising and non-ionising radiation.^[2] ARPANSA works under the guidance of the Australian Radiation Protection and Nuclear Safety Act of 1998 as the national regulatory body of radiation in Australia, with independent departments within each state and territory that regulate radiation within each of their jurisdictions.^[2]

ARPANSA's responsibilities include:^[3][4]

• Regulating the use of ionising radiation
• Setting national standards for radiation use
• Protecting citizens from radiation exposure
• Promoting the safe use of radiation in medicine
• Enforcing national radiation standards
• Providing advice to the Australian government and community about radiation or nuclear issues

ARPANSA evaluates research conducted by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and other foundations to set standards founded on extensive research.^[5]

Both ionising and non-ionising radiation is present in Australia, and can be found from man-made sources, or in natural sources as background radiation.^[6] Ionising radiation is radiation that does not exceed wavelengths over 100 nanometres, whereas non-ionising radiation exceeds wavelengths of 100 nanometres.^[7] Some of the common man-made sources of ionising radiation in Australia include x-rays, CT scans and naturally-found radioactive materials.^[3] The common sources of non-ionising radiation include mobile phones, power lines and the sun.^[3][8]

The average Australian is exposed annually to radiation at a level of 1,500-2,000 μSv, which is low in comparison to other countries, such as the 7,8000 μSv annual level reported in Cornwall, United Kingdom.^[9] These amounts are considered to be natural background radiation levels and exposure to this is not harmful,^[9] but radiation can also be used for a variety of health-related purposes. Unlike natural background radiation, there are several risks involved with radiation and nuclear services when used for medical purposes, including increased cancer prevalence.^[5] Because of these risks, an agency is required to manage and regulate their use to ensure the safety of all Australians.^[5]

From 1935–1972, the authorising body governing radiation in Australia was the Commonwealth X-Ray and Radium Laboratory. This was replaced by the Commonwealth Radiation Laboratory (1972–1973), and then the Australian Radiation Laboratory (1973–1999).^[10] In 1999, the Australian Radiation Laboratory then merged with the Nuclear Safety Bureau to create one agency that governed radiation and nuclear safety, ARPANSA.^[11] Since its establishment, ARPANSA has erected offices both in Sydney, NSW, and Melbourne, Victoria.^[11]

ARPANSA sets national radiation standards that must be abided by all Australian businesses. ARPANSA consults other health agencies globally, as well as research from relevant disciplines, and forms the standards based on this evidence.^[2][12] The standards are then founded on the recommendations from the ICNIRP based on their years of research.^[2][13] The IAEA’s standards are also considered when setting ARPANSA’s standards, and are established to assign responsibility of safe methods with use of ionising radiation.^[5]

All standards set by ARPANSA must also be assessed by the Australian government, such as the standard for radiofrequency electromagnetic radiation (RF EMR) that was set by ARPANSA in 2002.^[2] This standard specified that adverse health effects can be avoided with RF EMR levels within the range of 3 kHz- 300 GHz.^[8] This rigorous process has not been utilised for standards surrounding ionising radiation, as it does not currently have an identified threshold for harm.^[2]

ARPANSA monitors compliance with their regulations and standards through regular inspections of radiological businesses.^[5] ARPANSA also holds the ability to make actions if non-compliance is recognised.^[5] Of the radiological licenses monitored by ARPANSA, there are over 65,000 individual sources and 36 facilities, with many of these operated by the Australian Nuclear Science and Technology Organisation.^[5][9]

The agency also aids Australian citizens by publishing daily solar ultraviolet radiation (UVR) levels for many locations in Australia.^[14] This UV radiation index is based on data received by ARPANSA's UV detectors from cities through Australia which continuously collect data and update the site each minute.^[14] This information also provides data for the Cancer Council’s SunSmart App.^[15] ARPANSA also works with the Cancer Council by providing testing of clothing, sunglasses and shade cloths, and provides labels to indicate when a product fits Australian sun-protective standards.^[15]

The most senior staff member of ARPANSA is the CEO, who is always appointed by the Governor-General, and each term as CEO cannot exceed five years.^[7] The CEO is currently Dr Gillian Hirth, who was appointed in March 2022.^[16] The majority of activities are regulated by the individual state and territory departments, with ARPANSA only regulating six different commonwealth entities.^[17] ARPANSA then assists the state/territory regulatory bodies to assure that radiation protection requirements are uniform nation-wide within Australia.^[2]

The individual regulatory bodies are as follows:^[17]

• NSW EPA
• QLD Health
• VIC Department of Health and Human Services
• SA EPA
• TAS Department of Health
• WA Radiological Council
• NT Department of Health

Under the ARPANS Act of 1998, the founding of ARPANSA also established the formation of the Radiation Health and Safety Advisory Council, the Radiation Health Committee and the Nuclear Safety Committee.^[7] All of these groups consist of the CEO and an individual to represent the interests of the general public, as well as other specialty members.

The functions of the Radiation Health and Safety Advisory Council include identifying emerging issues relating to radiation protection and nuclear safety and examine concerning matters, among others.^[7] The members include:^[7]

• Two radiation control officers
• An individual nominated by the chief minister of the NT
• Eight other members

The functions of the Radiation Health Committee include developing national standards for radiation protection and create policies to adhere by, among others.^[7] The members include:^[7]

• A radiation control officer from each state/territory
• A nuclear safety committee representative
• Two other members

The Nuclear Safety Committee reviews and assesses the effectiveness of the current standards and codes, and to advise the CEO of any issues relating to nuclear safety.^[7] The members include:^[7]

• A radiation health committee representative
• A local government representative
• Eight other members

After a new quality testing system was implemented at ARPANSA, the agency was accredited by the National Association of Testing Authorities (NATA) to ISO/IEC 17025 in 2007.^[18] After the new accreditation, ARPANSA calibration reports then became recognised internationally under the Mutual Recognition Arrangement (MRA).^[18]

In 2018, the director general of the Radiation and Nuclear Safety Authority in Finland, Petteri Tiipana, stated that "Australia has demonstrated a strong commitment to continuous improvement in nuclear and radiation safety and in regulatory oversight of such facilities and activities".^[17] Following this in 2019, the deputy CEO and head of radiation health services at ARPANSA was appointed chair the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR).^[19] The position was previously held by Dr Hans Vanmarcke of the Nuclear Research Centre in Belgium and will be chaired by Dr Gillian Hirth of ARPANSA for sessions 66 and 67 in 2019 and 2020.^[19] The appointment of Dr Hirth to UNSCEAR was considered to be a recognition of her expertise and leadership in radiation health.^[19]

Since the 1980s, ARPANSA has had an ongoing collaboration with Cancer Council Victoria (CCV).^[20] This collaboration has included collaborating on research to increase understanding on protective sun behaviours and raise awareness about exposure to radiation.^[20] In 2016, ARPANSA and CCV signed a Memorandum of Understanding to improve health in regards to radiation exposure and solar ultraviolet radiation.^[20] In 2017, ARPANSA were then recognised as a SunSmart workplace by the then Assistant Minister for Health Dr David Gillespie.^[15] Prior to this recognition, CCV had only recognised schools and childhood centres in their commitment to protect staff from UV radiation.^[15] CCV’s Prevention Director Craig Sinclair commented that the recognition came at a good time due to it occurring during National Skin Cancer Action Week.^[15]
