Nebraska Administrative Code › Topic - HEALTH AND HUMAN SERVICES SYSTEM › Title 180 - CONTROL OF RADIATION › Chapter 19 - LICENSES AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS › Section 180-19-022 - DETECTION OF LEAKING SOURCES

Current through June 17, 2024
022.01
DRY-SOURCE STORAGE.
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 Department, NRC 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 200
  becquerels (0.005 microcurie) of radioactive material and must be performed by
  a person approved by the Department, NRC or an Agreement State to perform the
  test.
022.02
POOL
  IRRADIATORS.
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 contamination check 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 clean up contamination in the pool if specifically
  provided for in written emergency procedures.
022.03
LEAKING
  SOURCE.
If a leaking source is detected, the licensee must arrange
  to remove the leaking source from service and have it decontaminated, repaired,
  or disposed of by the Department, NRC or an Agreement State licensee authorized
  to perform these functions. The licensee must 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 must 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 product
  are found, the licensee must arrange to have them decontaminated or disposed of
  by the Department, NRC or an Agreement State licensee authorized to perform
  these functions. If a pool is contaminated, the licensee must arrange to clean
  the pool until the contamination levels do not exceed the appropriate
  concentration in 180 NAC 4, Table 2, Column 2. Appendix 4-B. See 180 NAC 3-026
  for reporting requirements.
