This unit describes the skills required to work safely with unsealed radioactive source and radioactive substance that emit ionising radiation. This involves assessing risks before conducting the assigned work tasks, using recommended controls, applying safe working rules and emergency response procedures, monitoring radiation levels and completing required documentation.This unit applies to authorised personnel who work at university, hospital, medical, veterinary, mining, analytical and research sites and are required to undertake tasks using an unsealed radioactive source and/or radioactive substance.The tasks may take place:at a mine or plant that processes radioactive ore and mineralswith instruments that emit ionising radiation at geotechnical , construction, mining and manufacturing sitesin a laboratory, analytical or research facility or licensed facility that handles radioactive materials or has radiation-emitting apparatusin a nuclear facilityThis unit applies to those undertaking radiation-related work activities, including:extracting, milling, processing and packing radioactive oresdecontaminating and servicing equipment that has been in contact with radioactive materialscollecting, preparing and testing samples containing radioactive materialsusing radionuclides in a laboratoryThe skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.Those undertaking this unit would work under the authorisation of a responsible person and with the advice of a radiation safety professional, such as a radiation safety officer.No licensing, legislative or certification requirements apply to unit at the time of publication.
