1. (a) Each user shall make or cause to be made such surveys as are necessary for compliance with all provisions of this regulation.

2. (b) Upon instruction from the Department or other official agency specifically designated by the Department, each user shall perform or cause to have performed, and shall permit the Department or said agency to perform, such reasonable tests as the Department or said agency deems necessary for the protection of life, health, or property, including, but not limited to, tests of:

   1. (1) Sources of radiation.
   2. (2) Facilities wherein sources of radiation are used or stored.
   3. (3) Radiation detection and monitoring instruments.
   4. (4) Other equipment and devices used in connection with utilization or storage of sources of radiation.

3. (c) Each sealed source other than sources listed below, shall be tested for contamination prior to initial use and for leakage at least every six months:

   1. (1) Hydrogen-3 or krypton-85 sources.
   2. (2) Sealed sources containing licensed radioactive material in gaseous form.
   3. (3) Source material.
   4. (4) Sources containing radioactive material with a half life of 30 days or less.
   5. (5) Sources of beta- and/or gamma-emitting radioactive material with an activity of 100 microcuries or less.

   6. (6) Sources of alpha and/or neutron-emitting radioactive material with an activity of 10 microcuries or less.

      In the absence of a certificate from a transferor indicating that a test has been made prior to the transfer, the sealed source shall not be put into use until tested. If there is reason to suspect that a source might have been damaged, it shall be tested for leakage before further use. Contamination and leak tests shall be capable of determining the presence of 0.005 microcuries of removable contamination. When any contamination or leak test reveals the presence of 0.005 microcuries or more of removable contamination the user shall immediately withdraw the source from use and shall cause it to be decontaminated and repaired or to be disposed of in accordance with applicable provisions of Group 2 of this subchapter. Two copies of a report shall be filed, within 5 days of the test, with the Department or other official agency specifically designated by the Department, describing the source involved, the test results, and the corrective action taken.

4. (d) The test sample shall be taken from the surface of the source, or source holder, or from the surface of the device in which the source is stored or mounted and on which one might expect contamination to accumulate. Where sealed sources are permanently mounted in devices or equipment, alternate tests for contamination and leakage may be approved by the Department.
5. (e) Tests for contamination and leakage, decontamination, and repair of sealed sources shall be performed only by persons specifically authorized by the Department to do so in accordance with provisions of Group 2 of this subchapter.
6. (f) Records of leak tests shall be maintained as specified in United States, title 10, Code of Federal Regulations, part 20, subpart L as incorporated by reference in section 30253..
