3701:1-46-46               Prototype tests for calibration or reference sources containing americium-241 or radium.

 

 

An applicant for a license pursuant to rule 3701:1-46-37 of the Administrative Code shall, for any type of source which is designed to contain more than one hundred eighty-five becquerels (0.005 microcuriesmicrocurie) of americium-241 or radium, conduct prototype tests, in the order listed, on each of five prototypes of such source, which contains more than one hundred eighty-five becquerels (0.005 microcuriesmicrocurie) of americium-241 or radium, as follows:

Prototype tests

 

Initial measurement	The quantity of radioactive material deposited on the source shall be measured by direct counting of the source.
Dry wipe test	The entire radioactive surface of the source shall be wiped with filter paper with the application of moderate finger pressure. Removal of radioactive material from the source shall be determined by measuring the radioactivity on the filter paper or by direct measurement of the radioactivity on the source following the dry wipe.
Wet wipe test	The entire radioactive surface of the source shall be wiped with filter paper, moistened with water, with the application of moderate finger pressure. Removal of radioactive material from the source shall be determined by measuring the radioactivity on the filter paper after it has dried or by direct measurement of the radioactivity on the source following the wet wipe.
Water soak test	The source shall be immersed in water at room temperature for a period of twenty-four consecutive hours. The source shall then be removed from the water. Removal of radioactive material from the source shall be determined by direct measurement of the radioactivity on the source after it has dried or by measuring the radioactivity in the residue obtained by evaporation of the water in which the source was immersed.
Dry wipe test	On completion of the preceding tests in this rule, the dry wipe test described in this rule shall be repeated.
Observations	Removal of more than one hundred eighty-five becquerels (0.005 microcuriesmicrocurie) of radioactivity in any test prescribed by this rule shall be cause for rejection of the source design. Results of prototype tests submitted to the director shall be given in terms of radioactivity in becquerels (or metric multiple, thereof) and percentper cent of removal from the total amount of radioactive material deposited on the source.
