About compliance monitoring

Routine compliance monitoring is scheduled by the Director for Radiation Safety (the Director) when a source licence is granted, renewed or varied. Compliance monitoring is conducted by enforcement officers appointed under the Radiation Safety Act 2016 (the Act). In most cases, compliance monitoring is conducted using announced compliance monitoring visits (on-site inspections).

The principal objective of routine compliance monitoring is to provide the Director with a high level of assurance that source licence holders are meeting the radiation safety requirements at the location or place from which the management, control and possession of radiation sources is authorised by the source licence. The radiation safety requirements are set out in section 5 (Interpretation) of the Act.

Schedule of routine compliance monitoring

Table 1 below indicates how the Director schedules routine compliance monitoring for source licence holders.  

The scheduling information provided in Table 1 does not prevent the Director from imposing higher or lower levels of compliance monitoring as a condition of a source licence as set out in sections 19(2) and (3) of the Act.

The scheduling information provided in Table 1 does not prevent the Director from conducting unannounced compliance monitoring for the purposes of monitoring compliance with the radiation safety requirements. 

The indication of compliance monitoring scheduling and the indication of practices or activities included in compliance monitoring categories Table 1 is provided for guidance purposes only. A monitoring year is 1 July to 30 June.
