WHS-PRO-GUI-014 Appendix 2

Appendix 2: Exempt Radiation Sources

The following radiation sources have been listed as exempt from being required to be used by a user licensee:

1. a sealed source apparatus, incorporating a sealed radioactive substance, used for chemical analysis or industrial gauging;
2. a radiation apparatus used for industrial gauging;
3. a cabinet radiation apparatus used for its intended use;
4. an enclosed radiation apparatus used for its intended use;
5. an ionising radiation source designed only for irradiating things, but not including use of the source by a person who is carrying out commissioning, maintenance or repair of the source;  Note: This does not apply to an ionising radiation source designed for irradiating individuals
6. a sealed radioactive substance, having an activity of not more than 370MBq, used for:
   1. calibration checks of measuring instruments; or
   2. quality control procedures undertaken for-
      1. another radiation source or a sealed source apparatus; or
      2. if another radiation source is used to carry out a radiation practice involving the production of images - any ancillary imaging equipment used in connection with the use of the other source to carry out the practice
7. a sealed radioactive substance, having an activity of not more than 4MBq, used for transferring anatomical landmarks to images produced using a gamma camera;
8. a radioactive substance, having an activity of not more than 500kBq, used for an in vitro test;
9. a sealed radioactive substance used for static elimination;
10. a fully enclosed analytical radiation apparatus used for its intended use;
11. a laser apparatus designed only for puncturing a person’s skin to obtain capillary blood samples but not including use of the apparatus by a person who is carrying out maintenance or repair of the apparatus;
12. a radioactive substance incorporated in an ionisation chamber smoke detector, but not including while the detector is being manufactured or repaired;
13. a radioactive substance containing the radionuclide promethium-147, hydrogen-3, or radium-226 incorporated in an item to produce light, but not including while the item is being manufactured or repaired;
14. a radioactive substance containing the radionuclide hydrogen-3 with an activity of less than 74GBq, incorporated in a gaseous tritium light device, if the device is being used as a safety, or warning sign, and complies with sections 2, 4 and 5 of the NHMRC ‘Appendix XXXIX - Recommendations for exemptions from licensing of gaseous tritium light devices’;
15. the following sealed radioactive substances with no more than the stated activity if used for teaching the characteristics and properties of radiation or radiation sources;

• Americium-241 20
• Caesium-137 200
• Cobalt-60 - 200 kBg
• Radium-226 20
• Strontium-90 80

16. the radionuclide krypton-85, incorporated in a cold cathode gas discharge tube, but not including while the tube is being manufactured or repaired.
