19. Council to exempt certain practices or any source within a practice from obtaining a licence

the radiation risk that may be caused to any member of the public by the conduct of the practice or the source concerned, is sufficiently low as to be of no regulatory concern of the Council;

the collective radiological impact of the practice or the source within the practice concerned is sufficiently low, as not to warrant the regulatory control of the Council under the prevailing circumstances;

the practice and the source within the practice concerned are inherently safe, with no applicable likelihood of a situation that could lead to a failure to meet the factors specified in paragraphs (a) or (b)

the practice is one that can be justified on the basis set out in section 22(1)(b).

specify the level of the effective dose expected to be incurred by a member of the public in one year from the conduct of the practice;

where the exemption relates to a source within a practice, specify the minimum levels of total activity of a given nuclide present on the premises at any one time and of the activity concentration in the nuclide used in the practice;

where it relates to an apparatus used in the practice, specify the levels of the ambient dose equivalent rate and the directional dose equivalent rate caused by such apparatus in normal operating conditions and the level of energy of the radiation produced by such apparatus.
