The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is pleased to announce The Hon Assistant Minister Ged Kearney MP’s appointment of Dr Jane Canestra as incoming Chair of the Radiation Health and Safety Advisory Council (RHSAC).

RHSAC is one of ARPANSA’s three statutory advisory bodies. Members provide guidance and advice to the CEO of ARPANSA on strategic and emerging issues, as well as matters of public concern relating to radiation protection and nuclear safety. Appointment terms are for three years.

Dr Canestra has been a General Member of the Council since 2015. She was an emergency physician with an extensive background in public health, emergency preparedness and response, including advising on planning responses to chemical, biological, and radiological (CBR) incidents at state and national levels.  

‘I am honoured to follow Dr Roger Allison as Chair of RHSAC, and thank both Dr Gillian Hirth and Assistant Minister Kearney for their support. I am looking forward to harnessing the collective expertise of Council and bringing further considered advice and support to ARPANSA as significant developments in radiation protection and nuclear safety occur in Australia,' said Dr Canestra.

Dr Gillian Hirth, CEO ARPANSA, congratulated Dr Canestra on her new role.

‘I am excited to welcome Dr Canestra as new Chair of RHSAC. As well as contributing eight years to the Council as a General Member, Dr Canestra brings considerable expertise to the role. Notably, she is highly experienced in the fields of emergency and risk management, and in health system and responder preparedness for radiological emergencies.’

Dr Hirth also thanked outgoing Chair, Dr Roger Allison for his decade-long commitment to – and guidance in – matters of radiation protection and nuclear safety.

‘I wish to extend our gratitude to Dr Allison for his significant service and contribution to the Agency. During his tenure, Dr Allison has shown himself to be a strong leader for the Council, providing invaluable, considered advice across a wide range of regulatory and public health issues.’

The Council has also welcomed three new General Members: Mr Christopher Perry, Associate Professor Catherine Olsen, Mr Stuart Parr and Mr Christopher Donovan.

‘The Council remains in good hands with Dr Canestra as Australia embarks on a new chapter of nuclear safety and security and ARPANSA continues our work to protect people and the environment,’ said Dr Hirth.

The International Atomic Energy Agency (IAEA) has released a comprehensive report reviewing the plans of Tokyo Electric Power Co. (TEPCO) and the Japanese Government to release treated radioactive water from the Fukushima Daiichi Nuclear Power Plant. The power plant was damaged during the 2011 earthquake and tsunami.

The planned release is an important step towards enabling the decommissioning of the Fukushima Daiichi Nuclear Power Plant, with recent reports of the internal damage to the reactors highlighting the ongoing risk if decommissioning is not managed and conducted in a timely manner.

ARPANSA has continually reviewed the information released by the Japanese Government and the IAEA, including the recently released IAEA report.

‘ARPANSA supports the IAEA’s assessment that the Japanese plans for discharge of water treated through the Advanced Liquid Processing System will not have an adverse impact on people and the environment,’ said ARPANSA CEO Dr Gillian Hirth.

The IAEA report showed that the approach to the discharge of treated water and associated activities by TEPCO and the Japanese Government are consistent with relevant international safety standards. The levels of radioactivity in the treated water would be kept within safe limits where there are no associated health risks to people or the environment in Japan or surrounding countries.

‘The damaged reactors require constant cooling and water used in cooling becomes contaminated with radioactive isotopes,’ said Dr Hirth.

‘Used water is treated to remove most of the radioactive isotopes and stored in tanks, however the storage capacity is limited and ultimately, a safe disposal pathway is needed.

‘In Australia, many hospitals routinely discharge radionuclides associated with medical isotopes into the sea and air.

‘Releasing treated radioactive water into the sea does not present health or environmental risks if the discharges are kept within strict limits,’ said Dr Hirth.

Prior to release of the treated water, TEPCO will further dilute the tritium to a level of radioactivity which is less than the level outlined in the Australian drinking water guideline for tritium.

The dose rate to environmental biota, such as fish, will also be less than the screening level used to ensure protection of the environment in Australia. A clearly defined plan for environmental monitoring by TEPCO and the Japanese Government is in place, and the IAEA will provide an independent sampling program to ensure transparency during the discharge phase, including providing continuous live monitoring data to be made available on their website.

The treated water will quickly dilute in the vastness of the Pacific Ocean, and radiation will be indistinguishable from background levels in waters surrounding Australia and the Pacific region.

The IAEA report was prepared by a panel of internationally recognised independent experts, including ARPANSA Chief Radiation Health Scientist Dr Rick Tinker, who participated in an individual capacity due to his expertise in this area.

ARPANSA research and public health advice on the potential radiological health impacts from the Fukushima Daiichi Nuclear Power Plant can be found on the ARPANSA website.

ARPANSA Acting CEO Dr Rick Tinker has removed a licence condition from the Australian Nuclear Science and Technology Organisation (ANSTO) Health Products facility following satisfactory implementation of recommendations following a 2018 safety review.

The licence condition was imposed in 2019 by then CEO Dr Carl-Magnus Larsson following a June 2018 direction for ANSTO to undertake an independent safety review.

The independent safety review considered occupational radiation safety of processes and operational procedures at ANSTO’s nuclear medicine facility (now ANSTO Health Products) –particularly those associated with quality control of molybdenum-99 samples.

The licence condition stated:

The licence holder must report to the CEO of ARPANSA on progress of the Independent Safety Review Action Plan implementation starting with a report for the last quarter of 2019 and then at six-monthly intervals until all actions are completed to the satisfaction of the CEO.

All actions from the independent safety review have been completed to the satisfaction of the CEO and the licence condition has now been removed.

ARPANSA will continue to monitor the ongoing implementation of recommendations through its regular inspection program.

Researchers from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) recently attended a workshop on techniques to measure radio waves in the 24 – 30 GHz range, frequencies which are now being used in the latest implementation of the 5G network.

ARPANSA’s Electromagnetic Radiation Exposure Assessment Assistant Director, Stuart Henderson, said the agency recently acquired two new probes for their spectrum analysers so that they can measure higher frequency 5G radio waves.

‘In 2022, when we conducted radio wave exposure measurements in Melbourne, all commercially available mobile phone services, including 5G, were using radio waves below 6 GHz,’ Dr Henderson said.

‘Now that 5G has started to use higher frequencies, we have updated our technology and practices so that we can continue to assess the community’s radio wave exposure.

‘The workshop provided an opportunity to discuss and explore those best practice methods to collect accurate measurements at 24-30 GHz. These techniques are outlined in recently updated standards by the International Electrotechnical Commission and have been adopted by Standards Australia.’

5G is the fifth generation of wireless technology used by telecommunications providers for mobile services and wireless internet.

ARPANSA’s measurement surveys have shown that exposure to radio waves in the environment from broadcast media and wireless technology is low – typically hundreds of times below the safety limits set in the ARPANSA Standard.

ARPANSA’s Radiation Monitoring Networks (RMN) team has resumed scheduled visits to the Comprehensive Test-Ban Treaty (CTBT) radionuclide monitoring station on the remote Pacific nation of Kiribati.

The station is part of an international network of more than 320 monitoring stations that aim to ensure no nuclear explosion goes undetected.

ARPANSA technical officers David Hardman and Jane McLeish travelled to Kiribati to provide training and support to local contractors and to conduct critical maintenance and repairs to the station. 

‘Radionuclide monitoring stations are a critical part of international efforts to deter nuclear weapons testing that could cause harm to people and the environment,’ said Mr Hardman.

‘Kiribati is a key location in the CTBT network due to its remoteness and its quite central location in the Pacific Ocean.’

ARPANSA is responsible for the operations of a total of 9 radionuclide monitoring stations in Australia, Antarctica and the Pacific region as part of Australia’s commitment to the Comprehensive Nuclear-Test-Ban Treaty (CTBT). In addition, ARPANSA’s experts work closely with colleagues in the Australian Safeguards and Non-Proliferation Office (ASNO) to ensure that Australia’s international obligations are met through the CTBT.

The stations filter air to collect particulate matter which is analysed for the presence of specific radionuclides that indicate a nuclear explosion has occurred. This material can then be traced using meteorological data to investigate the potential location of a radiological release.

‘Travel restrictions relating to the COVID-19 pandemic impacted our maintenance schedule, so it is great to be able to get back to Kiribati to perform this critical maintenance,’ said Mr Hardman.

‘Fortunately, the local contractors have been able to keep the station running with at least 95% data availability, which is impressive given the circumstances and the long periods of isolation,' Mr Hardman added.

Maintenance work included critical repairs and upgrades to power systems, air sampling equipment and gamma radiation detectors.

ARPANSA’s involvement in the CTBT program is a core element of its commitment to nuclear safety on an international scale, as we work to protect people and the environment from the harmful effects of radiation.

ARPANSA and Swinburne University’s systematic map of 334 papers was published in May 2023. While there is currently no substantiated evidence of harm, it highlights the need for more high-quality research into the effects of radio waves from high-frequency wireless technology such as 5G on plants and animals.

This research was led by the Australian Radiation Protection and Nuclear Safety Agency’s (ARPANSA) Health Impact Assessment Assistant Director Associate Professor Ken Karipidis.

‘At ARPANSA, our mission is to protect people and the environment from the harmful effects of radiation’ A/Prof Karipidis said.

‘This map presents all the available research on the impact of radio waves on plants and animals in the environment. It specifically highlights areas where further research is required.’

‘Future research should investigate the effect of radio waves at higher frequencies such as those used by 5G and future technologies.

‘This map is particularly timely given the public concern over the impact of the 5G network and other telecommunications sources on the environment.’

The International Commission on Non-Ionizing Radiation Protection (ICNIRP), of which A/Prof Karipidis is a Main Commission member, is currently preparing a statement on the environmental effects of radio waves.

This systematic map will help to inform that ICNIRP project.

ARPANSA will continue to evaluate scientific evidence on potential effects of radio waves as part of its role to protect people and the environment.

The systematic map was published in the peer-reviewed scientific journal Environmental Evidence.

A summary of the research has been published on our website. 

Australia’s Chief Metrologist Bruce Warrington visited the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) on Tuesday 9 May to assess and re-authorise our primary standards for ionising radiation dosimetry.  

ARPANSA’s Chief Medical Radiation Scientist Dr Ivan Williams says the dosimetry of ionising radiation is maintained by the agency so that the treatment and detection of diseases such as cancer is safe for Australian and New Zealand patients.  

Dr Williams explained that a great deal of effort, combining computer modelling and measurement, is performed to ensure our standard is accurate.  

He says the final proof of accuracy is the decadal comparison to primary standards of other countries through The International Bureau of Weights and Measures in Paris.  

‘Our primary standards’ consistency is excellent,’ Dr Williams said.  

‘The national primary standard is used to calibrate equipment used by hospitals to ensure that their own radiation therapy machines are delivering the correct dose.  

‘This reduces the chance of radiotherapy accidents in Australia, whereby underdosing or overdosing could cause significant harm to patients.  

‘Higher precision treatment also means the doctor’s prescription is more closely followed.’ 

Each year, around 70,000 Australians will be treated with radiotherapy for cancer. ARPANSA seeks to ensure that all use of radiation in medical procedures is justified and safe. 

The standards are maintained under an authorisation from the National Measurement Institute under the National Measurement Act 1960. 

The National Measurement Institute Standards Authorisation Committee meets each year to authorise the standards for radiation dose and radioactivity which are maintained at ARPANSA and the Australian Nuclear Science and Technology Organisation (ANSTO).

Scientists at the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) have published a paper that shows the average exposure to radio waves from wireless technology in Melbourne is more than 700 times below the safety limit.

ARPANSA’s Electromagnetic Radiation Exposure Assistant Director Dr Stuart Henderson led the research.

He says that the reason they undertook the study was to find out what the public’s typical exposure to radio waves was in public places like local parks or residential streets.

‘In March and April 2022, we collected measurements at 50 sites across Melbourne,’ Dr Henderson said.

‘While environmental exposure from wireless technology like Wi-Fi, broadcast media, and mobile phones was different in each location, in every case this exposure was still well below the Australian safety limit.’

Dr Henderson said the last time the agency conducted a large-scale survey like this was in 2013.

‘It’s interesting to see the different radio wave exposures over time. Back in 2013, 4G had only just been introduced and analogue TV had recently been replaced by digital TV transmissions,’ he said.

‘The 2022 measurements were ARPANSA’s first study measuring radio waves used in the 5G network. So, it is interesting to see how that fifth generation of mobile phone technology contributes to environmental exposure.

‘In future studies we would like to assess radio wave exposure at other Australian cities and regional towns.’

The article was published in peer-reviewed journal Radiation Protection Dosimetry in March 2023.
