Section He-P 4034.10 - Leak Testing and Replacement of Sealed Sources

(a) The replacement of any sealed source fastened to or contained in a radiographic exposure device and leak testing of any sealed source shall be performed by persons authorized to do so by DHHS/RHS, another agreement state, or the Nuclear Regulatory Commission.

(b) The opening, repair, or modification of any sealed source shall be performed by persons specifically authorized to do so by DHHS/RHS, another agreement state, or the Nuclear Regulatory Commission.

(c) Each licensee who uses a sealed source shall have the source tested for leakage at intervals not to exceed 6 months.

(d) The leak testing of a sealed source shall include:

(e) The licensee shall maintain records of the leak tests in accordance with He-P 4034.27.

(f) Unless a sealed source is accompanied by a certificate from the transferor that shows that it has been leak tested within 6 months before the transfer, it shall not be used by the licensee until tested for leakage.

(g) Sealed sources that are in storage and not in use shall not require leak testing.

(h) Sealed sources that are in storage and not in use shall be tested before use or transfer to another person if the interval of storage exceeds 6 months.

(i) Any test conducted pursuant to He-P 4034.10 that reveals the presence of 185 becquerel (0.005 mCi) or more of removable radioactive material shall be considered evidence that the sealed source is leaking.

(j) If a sealed source is found to be leaking, the licensee shall immediately withdraw the equipment involved from use and shall have it decontaminated and repaired or disposed of in accordance with He-P 4000.

(k) If a sealed source is found to be leaking, a report must be filed with DHHS/RHS within 5 days of the test, describing the equipment involved, the test results, and the corrective action taken. A copy of the report shall be sent to DHHS/RHS in accordance with He-P 4001.08.

(l) Each exposure device using depleted uranium (DU) shielding and an S-tube configuration shall:

(m) Should the testing required in He-P 4034.10(l) reveal the presence of 185 becquerel (0.005 mCi) or more of removable DU contamination, the exposure device shall be removed from use until an evaluation of the wear of the S-tube has been made.

(n) Should the evaluation in He-P 4034.10(m) reveal that the S-tube is worn through, the device shall not be used again.

(o) DU shielded devices shall not have to be tested for DU contamination while in storage and not in use.

(p) Before using or transferring a DU device, the device shall be tested for DU contamination if the interval of storage exceeds 12 months.

(q) A record of the DU leak-test shall be made in accordance with He-P 4034.27.
