Oregon Administrative Rules › Chapter 333 - OREGON HEALTH AUTHORITY, PUBLIC HEALTH DIVISION › Division 121 - LICENSING AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS › Section 333-121-0340 - Detection of Leaking Sources

Current through Register Vol. 63, No. 7, July 1, 2024
(1)
			 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
			 Authority, the Nuclear Regulatory Commission, an Agreement State, or a
			 Licensing 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
			 200 becquerels (0.005 _Ci) of radioactive material and must be performed by a
			 person approved by the Authority, the Nuclear Regulatory Commission, an
			 Agreement State, or a Licensing State to perform the test.
(2) 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 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 24
			 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 clear up
			 contamination in the pool if specifically provided for in written emergency
			 procedures.
(3) 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 Authority,
			 the Nuclear Regulatory Commission, an Agreement State, or a Licensing State
			 licensee that is authorized 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 Authority, the Nuclear Regulatory
			 Commission, an Agreement State, or a Licensing State licensee that is
			 authorized 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 Table 2, Column 2, Appendix B of  10 CFR 20 .
			 See
			 333-120-0700  for reporting requirements.
