459.2923. Specific licenses: Manufacture or initial transfer of calibration or reference sources

1. An application for a specific license to manufacture or initially transfer calibration or reference sources which contain americium-241 or radium-226 for distribution to a person who holds a general license issued pursuant to NAC 459.224 will be approved:

(a) If the applicant satisfies the general requirements of NAC 459.238;

(b) If the applicant submits sufficient information regarding each type of calibration or reference source relating to the evaluation of the potential radiation exposure, including, without limitation:

(1) The chemical and physical form of the source and maximum quantity of americium-241 or radium-226 in the source;

(2) The details of construction and design of the source;

(3) The details of the method of incorporation and binding of the americium-241 or radium-226 in the source;

(4) The procedure for and results of a prototype testing of a source designed to contain more than 0.005 microcurie (185 becquerels) of americium-241 or radium-226 in order to demonstrate that the americium-241 or radium-226 contained in each source will not be released or removed from the source under normal conditions of use;

(5) The details of quality control procedures which will be followed in the manufacture of the source;

(6) A description of the labeling to be affixed to the source or the storage container for the source; and

(7) Any additional information, including experimental studies and tests, required by the Division to facilitate a determination of the safety of the source;

(c) If each source contains not more than 5 microcuries (185 kilobecquerels) of americium-241 or radium-226; and

(d) If the Division determines, for any source which contains more than 0.005 microcurie (185 becquerels) of americium-241 or radium-226 that:

(1) The method of incorporation and binding of the americium-241 or radium-226 in the source is such that the americium-241 or radium-226 will not be released or removed from the source under normal conditions of use and handling of the source; and

(2) The source has been subjected to, and has passed in a satisfactory manner, the appropriate tests required by subsection 2.

2. The applicant shall subject at least five prototypes of each source that is designed to contain more than 0.185 kilobecquerel (0.005 microcurie) of americium-241 or radium-226 to the following tests:

(a) The initial quantity of radioactive material deposited on each source is measured by direct counting of the source.

(b) The sources are subjected to tests that adequately take into account the individual, aggregate and cumulative effects of environmental conditions expected in service that could adversely affect the effective containment or binding of americium-241 or radium-226, such as physical handling, moisture and water immersion.

(c) The sources are inspected for evidence of physical damage and for loss of americium-241 or radium-226, after each stage of testing, using methods of inspection adequate for determining compliance with the criteria in paragraph (d).

(d) Source designs are rejected for which the following has been detected for any unit: Removal of more than 0.185 kilobecquerel (0.005 microcurie) of americium-241 or radium-226 from the source or any other evidence of physical damage.
