The Regulation governs the management, use, and security of radioactive substances and radiation apparatus in New South Wales. It defines key terms such as “radioactive substance,” “security enhanced source,” and “radiation accident,” and establishes licensing and accreditation requirements. It provides exemptions for certain substances, apparatus, and professionals, including medical trainees and dental practitioners under supervision. Security provisions require detailed plans for handling and transporting radioactive sources, with specific measures based on source categories. Identity checks and reporting obligations apply for breaches and accidents. Radiation safety measures include dose limits for workers and the public, mandatory monitoring devices, and record-keeping. Employers must inform workers of hazards and maintain radiation management plans. Voluntary exposure for research is strictly regulated. The regulation addresses disposal and transport of radioactive materials, defines radiation accidents, and imposes duties to report and investigate such incidents. Public health protections include a ban on commercial cosmetic tanning services and requirements for warning signs. Miscellaneous provisions cover the appointment of safety officers, record destruction protocols, and fee structures for licences and approvals. Penalty notice offences are specified for breaches, with fines varying by offence and entity type.
