Current through Register No. 45, November 7, 2024

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:

(1) The model number;

(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; and

e. 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.
