§ 32.59 Same: Leak testing of each source.
Each person licensed under § 32.57
shall perform a dry wipe test upon each
source containing more than 3.7
kilobecquerels (0.1 microcurie) of
americium-241 or radium-226 before
transferring the source to a general
licensee under § 31.8 of this chapter.
This test shall be performed by wiping
the entire radioactive surface of the
source with a filter paper with the
application of moderate finger pressure.
The radioactivity on the paper shall be
measured by using radiation detection
instrumentation capable of detecting
0.185 kilobecquerel (0.005 microcurie)
of americium-241 or radium-226. If this
test discloses more than 0.185
kilobecquerel (0.005 microcurie) of
radioactive material, the source shall be
deemed to be leaking or losing americium-241 or radium-226 and shall
not be transferred to a general licensee
under § 31.8 of this chapter or
equivalent regulations of an Agreement
State.
