Ohio Administrative Code › Title 3701:1 - Radiation Control › Chapter 3701:1-52 - Licensing and Safety Requirements for Irradiators › Section 3701:1-52-22 - Detection of leaking sources

Current through all regulations passed and filed through July 1, 2024
(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 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."
