1.10.1
Testing
				  for Leakage or Contamination of Sealed Sources
A. The licensee in possession of any sealed
				  source shall assure that:
1. Each sealed
				  source, except as specified in §1.10.1(B) of this Part, is tested for
				  leakage or contamination and the test results are received before the sealed
				  source is put into use unless the licensee has a certificate from the
				  transferor indicating that the sealed source was tested within six (6) months
				  before transfer to the licensee.
2.
				  Each sealed source that is not designed to emit alpha particles is tested for
				  leakage or contamination at intervals not to exceed six (6) months or at
				  alternative intervals approved by the Agency, after evaluation of information
				  specified by §7.6.17 of this Subchapter, another Agreement State or the
				  U.S. Nuclear Regulatory Commission.
3. Each sealed source that is designed to
				  emit alpha particles is tested for leakage or contamination at intervals not to
				  exceed three (3) months or at alternative intervals approved by the Agency,
				  after evaluation of information specified by §7.6.17 of this Subchapter,
				  another Agreement State or the U.S. Nuclear Regulatory Commission.
4. For each sealed source that is required to
				  be tested for leakage or contamination, at any other time there is reason to
				  suspect that the sealed source might have been damaged or might be leaking, the
				  licensee shall assure that the sealed source is tested for leakage or
				  contamination before further use.
5. Tests for leakage for all sealed sources,
				  except brachytherapy sources manufactured to contain radium, shall be capable
				  of detecting the presence of one hundred eighty-five (185) Bq (five one
				  thousandths (0.005) µCi) of radioactive material on a test sample. Test
				  samples shall be taken from the sealed source or from the surfaces of the
				  container in which the sealed source is stored or mounted on which one might
				  expect contamination to accumulate. For a sealed source contained in a device,
				  test samples are obtained when the source is in the "off" position.
6. The test for leakage for brachytherapy
				  sources manufactured to contain radium shall be capable of detecting an
				  absolute leakage rate of thirtyseven (37) Bq (one one thousandth (0.001)
				  µCi) of radon-222 in a twenty-four (24) hour period when the collection
				  efficiency for radon-222 and its daughters has been determined with respect to
				  collection method, volume and time.
7. Tests for contamination from radium
				  daughters shall be taken on the interior surface of brachytherapy source
				  storage containers and shall be capable of detecting the presence of one
				  hundred eighty-five (185) Bq (five one thousandths (0.005) µCi) of a
				  radium daughter which has a halflife greater than four (4) days.
