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. The Australian Clinical Dosimetry Service (ACDS) is a dosimetry audit service offered by ARPANSA to Australian and New Zealand radiotherapy centres. The ACDS was launched in 2010 and delivers a world-class radiotherapy dosimetry audit program to private and public customers on a cost recovery basis, where the client pays for the services. The audit program assesses the dosimetry of external beams radiotherapy improve patient safety by reducing systemic dosimetric risk to the patient through remote and on-site audits of the radiation delivered. The ACDS works closely with professional radiation oncology organisations and conducts research leading to scientific contributions in publications and conferences of national and international relevance. The key duties of the position include In this role you will support and perform ACDS dosimetry audits for radiation oncology facilities throughout Australia and New Zealand. The work entails direct engagement with the customers' medical physicist and radiation therapist teams, gathering the planned data, performing the audit measurements and generating audit reports. In addition, you will provide technical, scientific and quality support for the dosimetry audit service including the OSLD and film dosimetry programs, equipment calibration and maintenance. This will require you to undertake ionising radiation dose measurements on ARPANSA's linear accelerators, X-ray and gamma ray sources. The ACDS undertakes research and development projects to improve and expand dosimetry audit capabilities to keep pace with emerging technologies introduced into radiation oncology clinical practice. The ACDS develops specialised software packages and Monte Carlo simulations for data analysis and interpretation of audit results. In this role you will have the opportunity to develop your experimental, scientific computer programming and analytical skills. The positions are based in ARPANSA's office in Yallambie, Victoria. The roles require significant on-site attendance for the use and access of resources and equipment. Flexible work arrangements may be negotiated. You will be required to travel regularly throughout Australia and New Zealand. There are two non-ongoing positions available. One non-ongoing maternity leave contract, and one non-ongoing 24-month contract. Key accountabilities Perform ACDS audits and develop an understanding for the clinical relevance and any actions arising from the audit outcome. Liaise with clients, analyse data and prepare reports. Support the OSLD and film dosimetry procedures for audits within the national radiotherapy audit program. Perform complex dosimetry measurements for the ACDS. Measurements will include treatment dose measurement using phantoms, beam characterisation and linac output. Perform extensive and comprehensive testing measurements of dosimeters, associated equipment and audit protocols. Participate in ACDS research and development activities as required, which may lead to conference presentations or peer reviewed publications.
