Ohio Admin. Code 3701:1-52-22 - Detection of leaking sources
(A) Each dry-source-storage sealed source
must be tested for leakage at intervals not to exceed six months using a leak
test kit or method approved by the United States nuclear regulatory commission,
the director, or an agreement state. 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. The test must be capable of
detecting the presence of one hundred eighty-five becquerels ( 0.005
microcurie) of radioactive material and must be performed by a person approved
by the United States nuclear regulatory commission, the director, or an
agreement state to perform the test.
(B) For pool irradiators, sources may not be
put into the pool unless the licensee tests the sources for leaks or has a
certificate from a transferor that a leak test has been done within the six
months before the transfer. Water from the pool must be checked for
contamination each day the irradiator operates. The check may be done either by
using a radiation monitor on a pool water circulating system or by analysis of
a sample of pool water. If a check for contamination is done by analysis of a
sample of pool water, the results of the analysis must be available within
twenty-four hours. If the licensee uses a radiation monitor on a pool water
circulating system, the detection of above normal radiation levels must
activate an alarm. The alarm set-point must be set as low as practical, but
high enough to avoid false alarms. The licensee may reset the alarm set-point
to a higher level if necessary to operate the pool water purification system to
clean up contamination in the pool if specifically provided for in written
emergency procedures.
(C) If a
leaking source is detected, the licensee shall arrange to remove the leaking
source from service and have it decontaminated, repaired, or disposed of by an
organization licensed by the United States nuclear regulatory commission, the
director, or an agreement state to perform these functions. The licensee shall
promptly check its personnel, equipment, facilities, and irradiated product for
radioactive contamination. No product may be shipped until the product has been
checked and found free of contamination. If a product has been shipped that may
have been inadvertently contaminated, the licensee shall arrange to locate and
survey that product for contamination. If any personnel are found to be
contaminated, decontamination must be performed promptly. If contaminated
equipment, facilities, or products are found, the licensee shall arrange to
have them decontaminated or disposed of by an organization licensed by the
United States nuclear regulatory commission, the director, or an agreement
state to perform these functions. If a pool is contaminated, the licensee shall
arrange to clean the pool until the contamination levels do not exceed the
appropriate concentration in accordance with table
II, appendix C of
table II of appendix C
to rule
3701:1-38-12
of the Administrative Code, "Annual Limits on Intake
(ALI) and Derived Air Concentrations (DAC) of Radionuclides for Occupational
Exposure; Effluent Concentrations; Concentrations for Release to Sanitary
Sewerage."
