For the purposes of this Guideline, in Canada, the federal AHJ is the CNSC

Examples of other exemption quantities or clearance levels include specific criteria set by the authority having jurisdiction (AHJ) and the criteria provided in IAEA No. GSR Part 3

1.2 Strategies and methodologies for the exemption or clearance process

This Guideline includes strategies and methodologies to optimize efforts and confidence levels of the exemption or clearance process, including

a) determining appropriate exemption quantities, conditional clearance levels, or unconditional clearance levels;

b) providing sampling and analysis techniques for assessing the radiological status of materials identified for exemption or clearance; and

b) non-effluent liquids.

Notes:

This Guideline addresses the radiological properties of materials intended for exemption or clearance.

This Guideline also covers radiological aspects of impacted materials with mixed contaminants; that is, materials that contain, or might contain, both nuclear substances and hazardous, chemical, or biological components

1.4 Exclusions

Notes:

In Canada, NORM and TENORM are addressed by Health Canada in Canadian Guidelines for the Management of Naturally Occurring Radioactive Materials (NORM) and are regulated by Provincial and Territorial governments.

While this Guideline is not applicable to the management NORM or TENORM, the principles in this Guideline can be useful for their management.

effluents directly resulting from patients who have received medically administered nuclear substances; and
