    The IAEA DS519 Draft Safety Guide - Protection of Workers Against Exposure due to Radon is now available for Member State comment and is open for comments from ARPS.

    What is the purpose of the guide? 

    The objective of the Safety Guide is to provide recommendations on protection of workers against exposure due to radon in workplaces, in planned and existing exposure situations, including the case of combined exposure to radon and other sources. The recommendations in the Safety Guide are based on the application of the graded approach. The Safety Guide is aimed at governments, regulatory bodies or other relevant competent authorities, employers, licensees, registrants, workers and service providers.

    Comments are requested in relation to: 

    • Relevance and usefulness: Are the stated objectives appropriate and are they met by the draft text?
    • Scope and completeness: Is the scope appropriate and is it adequately covered by the draft text? 
    • Quality and clarity: Does the guidance in the draft text represent the current consensus among specialists in the field and is this guidance expressed clearly and coherently? 

    Please submit comments by 21 March 2022 through the ARPANSA Have Your Say page

    On the 3rd October 2021, ARPS provided feedback to the International Radiation Protection Association on the paper “Keeping the ICRP Recommendations Fit for Purpose”. ARPS has been asked to revisit their feedback and provide only the Top 3 Priorities for ARPS.

    This is an opportunity to have input on the future of radiation protection. Please find attached the original feedback provided by ARPS. Below are the top 3 priorities identified based on feedback received to date.

     Please provide feedback by COB 13th December 2021

     Top 3 Priorities

    1. There is consensus among ARPS members that the system of protection must be  clear, logical and practical. Although the system is generally effective, in its current form it is  viewed as complex. Feedback indicates that this contributes to difficulty implementing the system. In general, ARPS does not support revisions that further complicate the system.
    2. ARPS proposes the introduction of a low dose threshold, e.g. between 1  and 5 mSv, with planned exposures below this threshold subject to no regulatory governance. The objective is to balance managing risks at low doses to the degree that the efforts of regulatory governance and financial burden is commensurate with comparable risks in other industries.
    3. There is a need to rethink whether “one system for all” is the right approach. By trying to bring everything under one system, it is getting more complicated and difficult to enact. It may be advantageous to have different systems for medical, natural, and nuclear.

    Title: Recent developments in radon progeny measurement and dosimetry

    Speaker: Andrew Yule, Science Officer - Monitoring and Emergency Response Section Radiation Health Services (Australian Radiation Protection and Nuclear Safety Agency)


    For several decades, radon progeny dosimetry was a relatively simple endeavour due to the ICRP recommendation to use the dose conversion convention (in ICRP publication 65) to calculate the radiation dose from any exposure to radon progeny. The ICRP now recommend the use of dose conversion factors (DCFs) based on the ICRP respiratory system model (in ICRP publication 137), which has raised many important questions about radon progeny dosimetry. While various aspects of these changes are under active consideration around the world, ARPANSA has focused on the practical impact of the changes. This has involved attempting to answer the following questions:

    How do you actually measure the DCF?

    Do the DCF’s suggested by the ICRP match real world conditions?

    Are the recommended DCF’s still appropriate as mining technology advances?

    Is there a place for site specific dose conversion factors, and if so where?

    In order to address these questions, we have developed new equipment and methods to provide accurate data in real world situations. Despite the challenges involved in working with nano-scale aerosols we have made significant progress which will be of interest to those involved in radon progeny measurement, dosimetry and regulation.

    ARPANSA has released a draft advisory note on the public health considerations for disposal of radioactive waste.

    The advisory note informs how health and well-being will be considered as part of licence applications such as those relating to the government’s proposed National Radioactive Waste Management Facility (NRWMF).

    ARPANSA is inviting interested stakeholders to provide feedback on the advisory note through an online consultation process.

    ‘This advisory note establishes an inclusive approach to community engagement when assessing potential impacts on health and well-being,’ said Dr Rick Tinker, Director Assessment and Advice at ARPANSA.

    ‘It is important that regulatory decisions take into account relevant social and psychosocial considerations in making an overall assessment of health impact.’

    ‘We are seeking input from industry, regulators, government and members of the public to engage in the consultation process.’

    The Australian Radioactive Waste Agency (ARWA) has announced an intention to establish a NRWMF in Napandee, near Kimba in South Australia. ARPANSA has not yet received any licence applications relating to the NRWMF. 

    The development of this advisory note forms part of ARPANSA’s preparations in anticipation of receiving a siting licence application in the coming years. 

    To provide feedback on the content of the advisory note, please fill out the form available on the Have Your Say section of ARPANSA’s website.

    Submissions close at 5pm AEDT on Wednesday 15 December.

    The advisory note will support ARPANSA’s role as the independent regulator of Commonwealth entities that use or produce radiation and ensure that community safety and wellbeing remain at the core of our work.

    The Radiation Health Committee (RHC), established under the Australian Radiation Protection and Nuclear Safety Act 1998 has the role of advising the CEO and the Radiation Health & Safety Advisory Council on matters relating to radiation protection, including formulating draft national policies, codes and standards for consideration by the Commonwealth, States and Territories.

    The RHC is seeking views on a new standard aimed at establishing a consistent approach to equipment compliance testing across States and Territories. The consultation is open until 31 January 2022 and is available on the ARPANSA website ( The RHC would be grateful if you could pass this on to your members for their awareness.

    Please do not hesitate to contact the RHC Secretariat at if you require further information.
