Organisational structure

Chief Executive Officer

Dr Carl-Magnus Larsson has held the position of Chief Executive Officer (CEO) since 2010.

The CEO’s functions (as set out in the ARPANS Act) include:

  • regulating Commonwealth radiation sources and facilities
  • promoting uniformity of radiation protection and nuclear safety policy and practices across jurisdictions of the Commonwealth, the states and the territories
  • providing advice on radiation protection, nuclear safety and related issues
  • undertaking research and providing services in relation to radiation protection, nuclear safety and medical exposures to radiation
  • monitoring the operations of ARPANSA, the Radiation Health and Safety Advisory Council (the Council), the Radiation Health Committee (RHC) and the Nuclear Safety Committee (NSC)
  • reporting on the operations of ARPANSA, the Council, RHC and NSC.

Executive Group

The CEO is supported by the Executive Group, which is comprised of three branch heads and four office heads. This group provides the CEO with high-level policy and strategic advice, and reports on matters relating to their individual business groups. Together, the CEO and the Executive Group form the leadership team responsible for the day-to-day management of ARPANSA.

During 2019–2020 the CEO commissioned a review of ARPANSA’s enabling services, which comprised the Corporate Office, the Office of the Chief Executive Officer and the Office of the General Counsel. The purpose of the review was to position the agency for the 2020s by strengthening the delivery of ARPANSA’s enabling services.

The review saw the Corporate Office cease to exist and split into two separate new offices: the Office for People Strategies and Wellbeing and the Office for Business Support. The Governance and Risk portfolio was reassigned to the Office of the Chief Executive Officer. No changes were made to the Office of the General Counsel.

The new structure came into place on 6 April 2020 and with it two new Office Head appointments. Mr David Peters was appointed Office Head and Director for People Strategies and Wellbeing. Mr Peters joined ARPANSA on 16 September 2019. Mr Niraj Pau was appointed Office Head of the Office for Business Support and also retains his previous role as Chief Financial Officer.

ARPANSA business groups

ARPANSA has seven business groups that deliver components of the agency’s strategies and services. Figure 1 shows ARPANSA’s organisational structure at 30 June 2020.

Regulatory Services Branch

Regulatory Services Branch has carriage of the regulation of safety and security of Commonwealth radiation sources and facilities. The Branch has four sections: Facility Safety, Source Safety and Security, Safety Systems, and National Codes and Standards. The Branch is responsible for assessing licence applications, monitoring compliance with the ARPANS Act and Regulations, undertaking enforcement actions, and providing regulatory guidance. It also promotes the development and implementation of a uniform regulatory framework across all jurisdictions. The costs for regulatory activities are recovered from licence holders and applicants as annual licence charges and application fees.

Radiation Health Services Branch

The Radiation Health Services Branch conducts hazard identification and exposure analysis of ionising and non-ionising radiation sources; evaluates the health risk to the public, workers and the environment; and mitigates health and environmental risks through provision of advice, assessments and services. The branch comprises three sections: Monitoring and Emergency Response, Assessment and Advice, and Radiation Protection Services. Its services operate on a fee-for-service basis including the Personal Radiation Monitoring Service, the ultraviolet radiation services and the radiofrequency electromagnetic radiation calibration service. The branch undertakes a number of national initiatives including our ultraviolet radiation monitoring network, the Australian National Radiation Dose Register and the radiation monitoring network established under the terms of the Comprehensive Nuclear‑Test-Ban Treaty. Emergency preparedness and response systems for field, network and laboratory measurements, and information management and decision support systems are maintained and aligned with national planning.

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: Medical Imaging, Primary Standards Dosimetry Laboratory, and the Australian Clinical Dosimetry Service. The Medical Imaging section is responsible for dose data collection and advice on patient safety within diagnostic imaging and nuclear medicine. The Primary Standards Dosimetry Laboratory maintains the Australian Primary Standard for absorbed dose and, by calibrating hospitals’ radiation detectors against the primary standard, ensures that a provider’s equipment is accurate. The Australian Clinical Dosimetry Service carries out dosimetric audits of linear accelerators used by radiotherapy providers in Australia and New Zealand and verifies that the radiation exposure of patients undergoing treatment is correct.

Office of the CEO

The Office of the Chief Executive Officer (OCEO) facilitates, coordinates and supports the activities of the CEO. The OCEO comprises three sections: Communications, Government and International Relations, and Governance and Risk. The OCEO leads collaboration and communication with the public and government, coordinates international engagement, and supports effective governance and risk management including maintenance of the Integrated Management System. The OCEO also provides advice to the agency and government on emerging and strategic issues.

Office for Business Support

The Office for Business Support (OBS) is home to a number of enabling services and works closely with all branches and offices across the agency to support their operations. The OBS is responsible for three sections: Finance, Digital Technologies, and Facilities and Engineering. The OBS is involved in continuing to modernise the delivery of customer-centric enabling services to the wider agency through finding opportunities to enhance business partnering, adoption of new technologies and continually reviewing of our business models to ensure the agency remains fit-for-purpose to deliver its strategic objectives. It also provides business intelligence and support to ARPANSA’s services to the Australian community, such as the calibration, auditing, monitoring and analytical services.

Office of the General Counsel

The Office of the General Counsel provides legal advice and strategic support to the agency with regard to all aspects of the agency’s operations and assists the CEO to achieve his statutory mandate. The Office of the General Counsel 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 policies and legislation. The Office also performs freedom of information and privacy functions on behalf of the agency.

Office for People Strategies and Wellbeing

The Office for People Strategies and Wellbeing (OPSW) develops people strategies and wellbeing practices that align with the employer responsibilities and deliver on ARPANSA’s strategic objectives. The Office utilises specialist human resources expertise in the areas of workforce planning, industrial relations, workplace health and safety, recruitment and payroll processing to deliver innovative workforce solutions and human resources best practice while driving a culture of continuous improvement.

The key services provided by the OPSW include workforce and succession planning, talent attraction and retention, leadership and capability development, as well as diversity and inclusion, and safety-focused health and wellbeing initiatives.
