A finely collimated x-ray beam incident upon part of a person's body may result in a high local exposure without necessarily affecting a film badge or other personnel dosimeter worn on another part of the body not in the exposed area. Any person may be issued a licence provided that the Council is satisfied that the necessary requirements have been met. It is here emphasised that in NSW only licensees or persons working under the direct supervision of a licensee may possess and store, transport, use of dispose of any radioactive substance or may possess and use any irradiating apparatus. Any one licensee may hold one, or both types of licence, and any one licence may include any number of items within the scope of that particular licence. A licensee may not vary the terms or conditions under which a licence is held, without first obtaining the Council's authority to do so.
Licences are renewable annually.
Appointed representatives of the Council are entitled to visit at any reasonable time, premises on which radioactive substances or irradiating apparatus are held. If the Council finds that the conditions in the licence are not being maintained, that licence may be entirely revoked. 8.2 Radiation Workers Students and technical staff undertaking radioactive work on behalf of a licensee are required to be supervised for the duration of such work. Persons below the age of 16 years may not be employed on work involving exposure to ionising radiations arising from radioactive substances or irradiating apparatus.
