Current through all regulations passed and filed through March 18, 2024
(A) Each licensee who uses a sealed source
shall have the source tested for leakage
. The licensee
shall keep a record of leak test results in units of microcuries and retain the
record for inspection by the
director for three years after the leak test is
performed.
(B) The wipe of
a sealed source must be performed using a leak test kit or method approved by
the
director, the United States nuclear regulatory
commission or an agreement state. The wipe sample must be taken from the
nearest accessible point to the sealed source where contamination might
accumulate. The wipe sample must be analyzed for radioactive contamination. The
analysis must be capable of detecting the presence of one hundred eighty-five
becquerels ( 0.005 microcurie) of radioactive material on the test sample and
must be performed by a person approved by the
director,
the United States nuclear regulatory commission or an agreement state to
perform the analysis.
(C) Sealed
sources must be tested at the following frequencies:
(1) Each sealed source (except an energy
compensation source (ECS)) must be tested at intervals not to exceed six
months. In the absence of a certificate from a transferor that a test has been
made within the six months before the transfer, the sealed source may not be
used until tested.
(2) Each ECS
that is not exempt from testing in accordance with paragraph (E) of this rule
must be tested at intervals not to exceed three years. In the absence of a
certificate from a transferor that a test has been made within the three years
before the transfer, the ECS may not be used until tested.
(D) If a sealed source is found to
be leaking the licensee shall:
(1) If the
test conducted pursuant to paragraphs (A) and (B) of this rule reveals the
presence of one hundred eighty-five becquerels ( 0.005 microcurie) or more of
removable radioactive material, the licensee shall remove the sealed source
from service immediately and have it decontaminated, repaired, or disposed of
by a United States nuclear regulatory commission or agreement state licensee
that is authorized to perform these functions. The licensee shall check the
equipment associated with the leaking source for radioactive contamination and,
if contaminated, have it decontaminated or disposed of by a United States
nuclear regulatory commission or agreement state licensee that is authorized to
perform these functions.
(2) The
licensee shall submit a report to the
directorwithin five days of receiving the test
results. The report must describe the equipment involved in the leak, the test
results, any contamination which resulted from the leaking source, and the
corrective actions taken up to the time the report is made.
(E) The following sealed sources
are exempt from the periodic leak test requirements set out in paragraphs (A)
to (D) of this rule:
(1) Hydrogen-3 (tritium)
sources;
(2) Sources containing
licensed material with a half-life of thirty days or less;
(3) Sealed sources containing licensed
material in gaseous form;
(4)
Sources of beta- or gamma-emitting radioactive material with an activity of 3.7
megabecquerels (one hundred microcuries) or less; and
(5) Sources of alpha- or neutron-emitting
radioactive material with an activity of three hundred seventy kilobecquerels
(ten microcuries) or less.
