Activity Standards Laboratory
ANSTO is the standards body for radioactivity measurement in Australia. The technical function for measuring radioactivity is housed within the Activity Standards Laboratory (ASL). Radionuclide metrology scientists in ASL employ unique, highly specialised radiation detection techniques to carry out precise measurements of radioactivity without reference to a calibration.
- Primary standards
ASL has the facilities and capabilities to perform accurate primary standardisations of various radionuclides. These primary standards may be verified by comparison with other international radionuclide metrology laboratories
- Secondary standards
Primary standards are transferred to the ASL secondary standard ionisation chamber in the form of radionuclide specific calibration factors. These calibrations make up the Australian secondary standards of activity of radionuclides
- Specialised radiation detection techniques (TDCR, 4πβγ)
- β and γ spectrometry
- Precise measurements against the national standard
- Australian Certified Reference Materials (ACRMs)
An ACRM is a reference material that has been certified under regulation 48 of the National Measurement Regulations 1999. An ACRM can be used to achieve traceability to the Australian national standard for radioactivity for a specific radionuclide and measurement geometry.
The ANMTP has been developed in response to the Australian and New Zealand Society of Nuclear Medicine (ANZSNM) expressed need for radionuclide metrology within nuclear medicine practices. The ANMTP can assist practices with regulatory compliance through technical and legal traceability to the Australian standard for important nuclear medicine based radionuclides. One of the main objectives of the program is to improve the health outcomes of Australians receiving nuclear medicine treatments through the more precise administration of nuclear medicine.
- Australian Industry Becquerel Traceability Program (AIBTP)
The AIBTP is offered to radiopharmaceutical producers and provides traceability to the national standard to assist in fulfilling regulatory requirements and facilitate trade of radiopharmaceutical products.
