ARPANSA and Monash University are seeking service providers to facilitate participant recruitment for a study on health impacts of non-ionising radiation cosmetic treatments, such as laser hair removal.     

ARPANSA’s Health Impact Assessment Assistant Director Ken Karipidis and researchers from Monash University are supervising the study, which will gather data on cosmetic procedures. 

The data collected will be used to understand if greater regulation is required for certain types of cosmetic procedures across Australia.

A/Prof Karipidis says that only Tasmania, Queensland and Western Australia have regulatory controls in place for cosmetic use of non-ionising radiation, although this is limited to certain light-based cosmetic applications like laser and intense pulsed light (IPL).

‘As the Australian Government’s primary authority on radiation protection, we want to ensure that appropriate measures are in place to keep people safe when undergoing cosmetic procedures that involve the use of non-ionising radiation,’ A/Prof Karipidis said.

The researchers are aiming to recruit businesses and service providers to help them identify individuals at their cosmetic clinics who they can survey as they receive treatments. 

With the survey data, PhD student Zoe Thomas will investigate the types of adverse effects that can occur, how frequently they occur, and in what circumstances.

‘As well as helping us understand the rate and type of injuries occurring, this study may also help to improve safety standards across the industry and provide greater assurance to potential clients,’ she said.

The International Atomic Energy Agency (IAEA) has acknowledged Australia’s commitment to nuclear safety in a report published June 2024. 

The report outlines the findings of the October 2023 IAEA Integrated Regulatory Review Service (IRRS) follow-up mission to Australia. The mission reviewed progress in national, legal and governmental frameworks for nuclear and radiation safety since the 2018 IRRS mission.  

ARPANSA Chief Executive Officer Dr Gillian Hirth AO welcomed the report, which found ARPANSA had addressed all previous recommendations for the agency. The IAEA also highlighted two areas of ‘good practice’ by ARPANSA, which it considers go above international best practice. 

‘With the changing nuclear landscape it’s now even more important than ever that Australia has consistent and comprehensive regulation to protect people and the environment from any harmful effects of radiation,’ Dr Hirth AO said.  

‘As the Australian Government’s primary authority on radiation protection, we promote consistent radiation protection for all Australians and comprehensive review of regulatory frameworks plays a critical role in delivering this vision.’  

An IRRS mission is a valuable regulatory benchmarking exercise involving peer review by overseas experts against IAEA Safety Standards. 

The IRRS team comprised seven international experts and three IAEA staff members, who worked together to review relevant reference material and interview ARPANSA, the Australian Radioactive Waste Agency and State and Territory regulatory bodies. 

The report noted that substantial progress had been made in response to the 2018 IRRS mission findings across all Australian Government and State and Territory participants. Out of the 23 recommendations and 12 suggestions from 2018, 16 recommendations and 10 suggestions have been successfully addressed and closed. 

The report was presented to the Australian Government and is now published on the ARPANSA website.

Summary

This study conducted  computer simulations comparing the specific absorption rate (SAR) of radiofrequency electromagnetic energy (RF-EME) at the male reproductive system from different mobile telecommunication frequencies. The study explored frequencies between 0.69 GHz and 4.9 GHz. The primary benefit of computing SAR instead of  considering incident power density (S_inc) is that it allows for more accurate comparison between exposures from electromagnetic fields of different frequencies. The study also performed calculations for exposure scenarios in three postures (standing, sitting and sleeping).

While maintaining an equal level of exposure across frequencies, the calculations showed that a higher frequency resulted in lower SAR at the reproductive system. Both a sitting and sleeping posture resulted in less exposure than a standing posture. When calculations were repeated for incident power densities at the exposure limits prescribed in the Institute of Electrical and Electronics Engineers (IEEE) guidelines the corresponding SAR values for each frequency band were highest at 2.2 GHz and decreased at higher or lower frequency bands. The same relationship between dose and posture was observed for exposures at the limit.

ARPANSA commentary

There is a growing volume of longitudinal studies (e.g. Ramirez-Vazquez et al., 2023; Markussen et al., 2022; Iakovidis et al., 2022), including those published by ARPANSA (Bhatt et al., 2024),  showing that public exposures to RF-EME have remained largely the same throughout the introduction of new communication technologies despite an overwhelming increase in the total usage of wireless telecommunication infrastructure by the public. The conclusions of this study provide similar reassurance by indicating that exposures to higher frequency RF-EME, like those used in newer communication technologies, contribute less SAR than an equivalent exposure from a lower frequency band. 

The calculations at exposure limits in this study were performed according to exposure limit guidance prepared by the IEEE. These guidelines, while similar to those in the Australian standard RPS-S1, are slightly less restrictive. The Australian standard is based on guidelines by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which are considered international best practice. More information on these differences can be found in a previous radiation literature survey. Notably, the study demonstrated the suitability of using power density limits (termed reference levels) which are easier to quantify for complying with SAR limits (termed basic restrictions) which are more difficult to quantify.

A World Health Organization (WHO) commissioned systematic review finds that radio wave exposure from mobile phones does not affect learning, memory, attention span and other cognitive functions like coordination.

Co-led by the Australian Radiation Protection and Nuclear Safety Agency’s (ARPANSA) Health Impact Assessment Assistant Director, Associate Professor Ken Karipidis, the review addresses a long-held community concern.  

‘One of the motivations for this research was to assess effects on the brain because mobile phones are usually held close to the head during calls,’ A/Prof Karipidis said.

‘One of the challenges of studying the effects of mobile phones on health is that it’s hard to separate radiation exposure from behavioural effects from social media and gaming on our cognition. 

‘Overall, this systematic review found that radio wave exposure from mobile phones does not affect cognition.’

The WHO systematic review was a collaboration between ARPANSA and Monash University. ARPANSA’s Dr Chris Brzozek and Dr Masoumeh Sanagou also contributed to the study. 

This review identified 3945 papers for consideration but only 5 studies were found to have appropriate methods and were included in the final analysis. The authors acknowledge that more high-quality research is needed to address all types of populations, radio wave exposures, and cognitive outcomes, particularly studies investigating environmental and occupational exposure in adults. 

The WHO commissioned a series of systematic reviews in 2019 to help them undertake an updated health risk assessment of radio wave exposure. These reviews will be used to help inform a new Environmental Health Criterion monograph on radiofrequency electromagnetic fields (RF-EMF). 

ARPANSA is supporting the systematic reviews and the development of the monograph.

Australia joined with Kazakhstan to co-host last week’s International Conference on Nuclear Security (ICONS) in Vienna.

Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) CEO, Dr Gillian Hirth, says ICONS is the International Atomic Energy Agency’s (IAEA) key event for sharing best practice across the global nuclear security community. 

‘The IAEA’s efforts in bringing together its member states every four years provides a crucial opportunity to discuss and exchange information on nuclear security,’ Dr Hirth said. 

At ICONS 2024, ARPANSA joined with the Australian Safeguards and Non-proliferation Office (ASNO) and the Australian Nuclear Science and Technology Organisation (ANSTO) to host a session sharing insights into national collaborative approaches. 

Australia’s continued support and engagement with the Asia Pacific to strengthen regional nuclear safety and security, and aspirations for the global future of nuclear security were key topics of discussion.

Dr Hirth also participated in a panel discussion, moderated by ARPANSA’s Senior Regulatory Officer on Nuclear and Radiological Security, Julie Murray, on shaping the future of nuclear security from a gender equality perspective. 

‘Australia is a strong advocate for gender parity; an important topic that I have a deep commitment to nurturing,’ Dr Hirth said.  

‘It was a pleasure to be able to share insights and highlight female technical experts and leaders who are making vital contributions to nuclear security.’

‘It is fundamental that we continue our work in advancing opportunities for women, particularly in leadership, as they are recognised key drivers in shaping our nuclear security future.’

‘ARPANSA continues to work closely with its Australian Government counterparts and the IAEA to promote national and international best practice to support nuclear security in our region and more broadly,’ Dr Hirth said.

The event was also an opportunity to establish ongoing connections with international counterparts, including a new cooperation agreement with the Authority for Nuclear Safety and Radiation Protection (ANVS) from the Netherlands.

ICONS 2024 was held at the IAEA headquarters in Vienna from 20 to 24 May 2024.

Airborne ultrasound exposure guidelines from 1984 are being revisited by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) due to their use in emerging technology. 

Airborne ultrasound is increasingly being used in virtual reality technology to create the experience of touch. Airborne ultrasound consists of inaudible sound waves that travel through air and are mostly produced in heavy industry, for example drilling, and in commercial products like burglar alarms. 

Extremely high levels of airborne ultrasound can cause ear damage, and excessive body heating that can lead to pain and burns. 

ICNIRP Vice-Chair elect and Health Impact Assessment Assistant Director at the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), Associate Professor Ken Karipidis, led the review and says the current guidelines are based on limited research and further studies are needed.

‘Based on the available research, the exposure limits set in the existing guidelines are still applicable today,' A/Prof Karipidis said.

‘However, when we assessed the evidence that has been published since 1984, we found there are significant data gaps that need to be addressed before ICNIRP can publish updated exposure guidelines.   

‘In particular, we'd like to know more about other health effects like effects on cognitive function and behaviour and non-specific symptoms such as headaches and fatigue.

‘This is particularly relevant given the expanded use of airborne ultrasound within the wider community. 

‘The effect of ultrasound on the human ear can vary according to age so it is also important for future research to determine the distribution of exposure levels where hearing damage can occur across the population.' 

As Australia’s primary radiation protection authority, ARPANSA works with leading international health authorities like ICNIRP to develop guidelines to protect the public and the environment from the harmful effects of radiation.

Summary

This review report published on behalf of the Swedish Radiation Safety Authority (SSM) aims to inform health risk assessment of exposure to electromagnetic fields (EMF). It included different study types (in vitro, animal, human and epidemiological) published in the year 2021 related to several EMF exposure types (static, low frequency or extremely low frequency, intermediate and radio frequency fields). A variety of outcomes (DNA damage, oxidate stress, animal behaviour, animal physiology, human cancer, reproduction, etc.) associated with EMF exposure were assessed. This report did not identify any new established causal relationships between EMF exposure and health risk. For example, epidemiological studies on static EMFs (e.g., from MRI) are limited and hence underlying mechanisms for rarely observed associations due to effect of static fields are unclear. The recent studies on extremely low frequency (ELF) magnetic field exposure do not provide any evidence whether the consistently observed association between ELF and childhood leukaemia is causal or not. Similarly, no definite conclusions can be drawn from a recent study on intermediate EMF exposure and human health effects. Several new studies on brain tumours and mobile phone use largely continue to provide no indication of health risk.

ARPANSA commentary

The overall conclusion of the report is similar to the conclusions provided in the previous years’ reports from the SSM. The strength of this report is that it was reviewed by a multidisciplinary team of experts evaluating a range of EMF exposure types and health-related endpoints, reviewing various types of evidence. Therefore, it consolidates all emerging evidence generated in the year 2021 while presenting its review findings. 

The findings of the report are consistent with the health risk advice from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), and other national and international organisations. For example, the health advice of ARPANSA on ELF-MF and radiofrequency field exposure, and the health risk assessment of radiofrequency fields by the US Food and Drug Administration on RF-EMF and Cancer, are in line with the findings from the report. The World Health Organization is currently assessing available evidence on potential human health effects of radiofrequency field exposure, including that associated with mobile phone use. ARPANSA is supporting this process to inform evidence-based health risk assessment of EMF exposures.
