The Act operates through a few interlocking concepts and statutory actors that determine risk allocation, decision authority and compliance obligations.
Person responsible for regulated material (s 6(1)): The Act defines, for the purposes of the regulatory regime, a person responsible as the owner of regulated material; a person storing, selling or giving away regulated material; and a person who has possession of regulated material. Two narrow exceptions exclude persons who possess material solely for the purpose of using it under a radiation user licence, and persons who have possession solely for the purposes of transporting the material. That definition is the primary gate to the management-licence duty in s 6(2).
Radiation management licence (s 6(2)): A person responsible for regulated material must hold a radiation management licence in respect of that material and comply with licence conditions. The licence is the primary legal authorisation to own, store, supply, lease or possess regulated material, subject to the exceptions and any Ministerial exemptions (s 6(3)-(5)).
Radiation user licence (s 7): Natural persons who use regulated material must hold a radiation user licence and comply with conditions. The Act treats user licences as personal authorisations tied to knowledge and competence requirements (s 9(6)(d)).
Accreditation (s 8): The Act requires accreditation for persons carrying out activities prescribed by regulations as consulting radiation experts or radiation security assessors. The accreditation is activity-specific and subject to regulation-prescribed scope and conditions.
Authority, Minister and Council: The regime distributes decision roles. The Authority functions as the licensing and accreditation decision-maker, regulator of conditions, record-keeper (public register, s 13C), and enforcer via suspension and cancellation powers (ss 9, 10, 12, 13). The Minister may grant exemptions from management-licence requirements (s 6(3)-(5)). The Council (a body created elsewhere in the principal Act) is a statutory adviser whose views the Minister or Authority may seek and take into account in licensing, exemptions and applications (s 6(5), s 9(8)).
Conditions and regulatory detail: The Act contemplates a wide range of conditions (s 13B(2)), including technical controls, place-specific conditions, equipment standards, works and remediation programs, and financial assurance requirements (s 13B(2)(a)-(e)). Conditions may require adherence to materials adopted into a National Directory, guidelines issued by the Authority, Australian Standards, or publications of the Australian Radiation Protection and Nuclear Safety Agency (s 13B(2)(f)). Many operational definitions and thresholds are left to the regulations: the activities requiring accreditation (s 8), the form and content of security plans and checks (s 14(3), s 14B(6)), the identity and security check particulars (s 14B(1)-(2)), the definition of a security enhanced source (s 14 note), and the particulars of security protection measures (s 14A(1)).
Security enhanced source and security plans (s 14): A security enhanced source is a sealed radioactive source prescribed by the regulations. Persons responsible for such sources must have source security plans and, where applicable, source transport security plans. Security plans must nominate a responsible natural person, set out protection measures, and be endorsed by a radiation security assessor before being made or amended (s 14(2), (4)-(6)). Persons given copies of plans are bound to comply with them in their dealings with the source (s 14(7)).
Screening and identity verification (s 14B): The Act mandates identity checks (to ascertain identity and residential address and any other prescribed information) and security checks for specific categories of persons dealing with security enhanced sources. There is a limited supervisory carve-out, but nominated persons and transporters must always undergo checks (s 14B(3)-(4)). The regulations set the content and process for checks (s 14B(6)).
Public register and privacy carve-out (s 13C): The Authority must maintain a publicly accessible register containing licence-holder names, licence types and numbers, expiry dates, status and other prescribed information, available free of charge at the principal office and on the website (s 13C(1)-(4)). The Act expressly provides that s 57 of the Privacy and Personal Information Protection Act 1998 does not apply to this register (s 13C(6)), which affects information handling obligations and public access.
Penalty structure and enforcement tools: The Act uses a mix of monetary penalties expressed in penalty units and criminal penalties including imprisonment for some offences. Penalty maxima are differentiated between corporations and natural persons in several provisions (notably ss 6, 13A, 14, 14A, 14B). Enforcement tools include licence suspension, cancellation, surrender controls, conditional approvals, and criminal penalties for non-compliance with licence duties and security obligations (ss 12-13A, 13B, 14-14B).
Delegation to regulations and external standards: Recurrent references to matters "prescribed by the regulations" and to documents adopted into the National Directory, Australian Standards and publications of the Australian Radiation Protection and Nuclear Safety Agency show that the Act establishes a framework while delegating technical detail and operational thresholds to subordinate instruments and external technical documents.
