Section 333-116-0200 - Requirements for Possession of Sealed Sources and Brachytherapy Sources(1) A licensee in possession of any sealed source or brachytherapy source must follow the radiation safety and handling instructions supplied by the manufacturer or equivalent instructions approved by the Authority, and must maintain the instructions for the duration of source use in a legible form convenient to users.(2) A licensee in possession of a sealed source must assure that: (a) 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 six months before transfer to the licensee; and(b) The source is tested for leakage at intervals not to exceed six months or at intervals approved by the Authority, another Agreement State, a Licensing State or the U.S. Nuclear Regulatory Commission in the Sealed Source and Device Registry (SS&D).(3) To satisfy the leak test requirements of this division, the licensee must assure that: (a) Leak tests are capable of detecting the presence of 185 Bq (0.005 uCi) of radioactive material on the test sample, or in the case of radium, the escape of radon at the rate of 37 Bq (0.001 uCi) per 24 hours;(b) Test samples are taken from the source or from the surfaces of the device in which the source is mounted or stored on which radioactive contamination might be expected to accumulate; and(c) For teletherapy units, test samples are taken when the source is in the "off" position.(4) A licensee must retain leak test records in accordance with OAR 333-100-0057. The records must contain the model number and serial number if assigned, of each source tested, the identity of each source radionuclide and its estimated activity, the measured activity of each test sample expressed in microcuries (Bq), a description of the method used to measure each test sample, the date of the test and the signature of the Radiation Safety Officer.(5) If the leak test reveals the presence of 185 Bq (0.005 uCi) or more of removable contamination, the licensee must: (a) Immediately withdraw the sealed source from use and store it in accordance with the requirements of these rules; and(b) File a report within five days of receiving the leakage test results with the Authority describing the equipment involved, the test results and the action taken.(6) A licensee need not perform a leak test on the following sources: (a) Sources containing only radioactive material with a half-life of less than 30 days;(b) Sources containing only radioactive material as a gas;(c) Sources containing 3.7 MBq (100 uCi) or less of beta or photon-emitting material or 370 kBq (10 uCi) or less of alpha-emitting material;(d) Seeds of iridium-192 encased in nylon ribbon; and(e) Sources stored and not being used. The licensee must, however, test each such source for leakage before any use or transfer unless it has been tested for leakage within six months before the date of use or transfer.(7) A licensee in possession of a sealed source or brachytherapy source must conduct a semi-annual physical inventory of all such sources in its possession. The licensee must retain each inventory record in accordance with OAR 333-100-0057. The inventory records must contain the model number of each source and serial number if one has been assigned, the identity of each source radionuclide and its estimated activity, the location of each source, date of the inventory and the signature of the Radiation Safety Officer.Or.
