ARPANSA at a glance

Our mission

Protection of people and the environment from the harmful effects of radiation

Our vision

Radiation safety is appropriately considered in societal decision-making

Radiation safety is addressed uniformly and effectively across Australia

Radiation safety in Australia is current international best practice

Our purpose

The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is the Australian Government’s primary authority on radiation protection and nuclear safety. Our purpose is to protect the Australian people and the environment from the harmful effects of radiation, through understanding risks, best practice regulation, research, policy, services, partnerships and engaging with the community.


Established by the Australian Radiation Protection and Nuclear Safety Act 1998 (ARPANS Act), ARPANSA commenced operations on 5 February 1999. ARPANSA replaced the Nuclear Safety Bureau and Australian Radiation Laboratory.

Responsible ministers and portfolio

ARPANSA sits within the Department of Health portfolio. The CEO, Dr Carl-Magnus Larsson, is the accountable authority of ARPANSA.

As at 30 June 2017, Dr Larsson reported to the Assistant Minister for Health.

Our outcome

ARPANSA has a single outcome as set out in the portfolio budget statement:

Protection of people and the environment through radiation protection and nuclear safety research, policy, advice, codes, standards, services and regulation.

Our staff

As at 30 June 2017, ARPANSA had 126 ongoing staff, six non-ongoing staff, and one statutory appointment.


ARPANSA has offices in Victoria (Yallambie) and New South Wales (Miranda). Over 83 per cent of staff are located in the Victorian office.


ARPANSA, on behalf of the Australian Government, aims to protect the Australian people and environment from the harmful effects of radiation.

ARPANSA is the independent regulator of Commonwealth entities that use or produce radiation. ARPANSA provides advice and services to the Australian community on radiation protection, nuclear safety, security, and medical exposures to radiation. The agency also undertakes internationally recognised research and promotes both national uniformity and the implementation of international best practice.

The Radiation Protection and Nuclear Safety Program, contained within the portfolio budget statement, describes four program objectives which ARPANSA pursues to protect the Australian people and the environment from the harmful effects of radiation. Two new objectives were developed for the 2017–21 corporate plan to reflect the important work of our supporting capabilities:

  • strengthen engagement with community and government
  • enhance organisational innovation, capability and resilience.

The 2016–17 strategic objectives are:

  1. Protect the public, workers and the environment from radiation exposure
  2. Promote radiological and nuclear safety and security, and emergency preparedness
  3. Promote the effective use of ionising radiation in medicine
  4. Ensure effective and proportionate regulation and enforcement activities

The General Counsel also provides legal advice and support to all ARPANSA staff to assist them in performing their functions and to ensure that in doing so they are compliant with relevant government policy and legislation.

Regulatory Services Branch

Regulatory Services Branch has main carriage of regulation of the safety and security of Commonwealth radiation sources and facilities.

Comprising four sections (Facility Licensing, Source Control, Continuous Improvement and Regulatory Assurance), the branch is ARPANSA’s principal driver for promoting a uniform regulatory framework across all jurisdictions. The costs for direct regulatory activities are recovered from application fees and annual licence charges.

Radiation Health Services Branch1

The Radiation Health Services Branch comprises three sections; Monitoring and Emergency Response, Assessment and Advice, and Radiation Protection Services. The branch provides radiation protection advice and assessments to the public and to government. It operates services on a fee-for-service basis including the Personal Radiation Monitoring Service, the ultraviolet radiation fabric testing service and a radiofrequency equipment calibration service. The branch operates a number of national initiatives including an ultraviolet radiation monitoring network, and the Australian National Radiation Dose Register. It also operates a radiation monitoring network established under the terms of the Comprehensive Nuclear-Test-Ban Treaty.

Medical Radiation Services Branch

The Medical Radiation Services Branch provides safety and quality advice on the use of radiation in medicine to all Australians. The branch has three sections. The Medical Imaging section is responsible for dose data collection and advice on patient safety within diagnostic imaging. The Radiotherapy section maintains the Australian primary standard for absorbed dose and, by calibrating hospitals’ radiation monitors against the primary standard, ensures that a provider’s equipment is accurate. The Australian Clinical Dosimetry Service audits linear accelerators used by radiotherapy providers in Australia, verifying that the radiation exposure of patients under treatment is correct.
