Section He-P 4035.21 - Requirements for Possession of Sealed Sources and Brachytherapy Sources(a) A licensee in possession of any sealed source or brachytherapy source shall follow the radiation safety and handling instructions supplied by the manufacturer or equivalent instructions.(b) A licensee in possession of a sealed source shall ensure that:(1) The source is tested for leakage before its first use unless the licensee has a certificate from the supplier indicating that the source was tested within 6 months before transfer to the licensee; and(2) The source is tested for leakage at intervals not to exceed 6 months or at intervals approved by DHHS/RHS, or another agreement state or the Nuclear Regulatory Commission in the Sealed Source and Device Registry.(c) To satisfy the leak test requirements of He-P 4035.21(b), the licensee shall ensure that leak tests are capable of detecting the presence of 185 becquerels (0.005 microcurie) of radioactive material on the test sample.(d) A licensee shall retain leak test records for 3 years.(e) The leak test records shall contain:(2) Serial number, if assigned, of each source tested;(3) The identity of each source radionuclide;(4) The estimated activity of each source radionuclide;(5) The measured activity of each test sample expressed in becquerels (microcuries);(6) The date of the test; and(7) The name of the individual who performed the test.(f) If the leak test reveals the presence of 185 becquerels (0.005 microcurie) or more of removable contamination, the licensee shall: (1) Immediately withdraw the sealed source from use and store, repair or dispose of it in accordance with the requirements of He-P 4023; and(2) File a report as described in He-P 4035.21(e) with DHHS/RHS within 5 days of receiving the leak test results describing the equipment involved, the test results, and the action taken.(g) A licensee: (1) Shall not be required to perform a leak test on the following sources:a. Sources containing only byproduct material with a half-life of less than 30 days;b. Sources containing only byproduct material as a gas;c. Sources containing 3.7 megabecquerels (100 microcuries) or less of beta or gamma-emitting material or 370 kilobecquerels (10 microcuries) or less of alpha-emitting material;d. Seeds of iridium-192 encased in nylon ribbon; ande. Sources stored and not being used; but(2) Shall test each such source in (g)(1) above for leakage before any use or transfer unless it has been tested for leakage within 6 months before the date of use or transfer.(h) A licensee in possession of a sealed source or brachytherapy source, except for gamma stereotactic radiosurgery sources, shall conduct a physical inventory of all such sources in its possession at intervals not to exceed 6 months.(i) The licensee shall retain each sealed source inventory record for 3 years.(j) The sealed source inventory records shall contain:(1) The model number of each source;(2) The serial number, if one has been assigned;(3) The identity of each source radionuclide;(4) The estimated activity of each source radionuclide;(5) The location of each source;(6) The date of the inventory; and(7) The name of the individual who performed the inventory.N.H.
