Illinois Administrative Code › Title 32 - ENERGY › Part 340 - STANDARDS FOR PROTECTION AGAINST RADIATION › Subpart E - TESTING FOR LEAKAGE OR CONTAMINATION OF SEALED SOURCES › Section 340.410 - Testing for Leakage or Contamination of Sealed Sources

Current through Register Vol. 48, No. 28, July 12, 2024
a) The licensee in possession of any sealed
				source shall assure that:
1) Each sealed
				source, except as specified in subsection (b) of this Section, is tested for
				leakage or contamination and the test results that confirm that the sealed
				source is not leaking or contaminated 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 6 months for beta and gamma
				emitting sources, or within 3 months for sources designed to emit alpha
				particles, 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 6 months or at alternative intervals approved by the Agency, pursuant to
				32 Ill. Adm. Code
				330.280(m),
				the U.S. Nuclear Regulatory Commission, an Agreement State or a Licensing
				State.
3) Each sealed source that
				is designed to emit alpha particles is tested for leakage or contamination at
				intervals not to exceed 3 months or at alternative intervals approved by the
				Agency, pursuant to 32 Ill. Adm. Code
				330.280(m),
				the U.S. Nuclear Regulatory Commission, an Agreement State or a Licensing
				State.
4) Each sealed source that
				is required to be tested for leakage or contamination shall be removed from
				service if there is reason to suspect that the sealed source may have been
				damaged or may be leaking or contaminated. The source shall be kept out of
				service until test results that confirm there is no leakage or contamination
				are received.
5) Tests for leakage
				for all sealed sources, except brachytherapy sources manufactured to contain
				radium, shall be capable of detecting the presence of 185 Bq (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 shall be obtained when the
				source is in the "off" position. If setting the source to the "off" position
				would disrupt the licensee's activities, test samples may be obtained while the
				source is in the "on" position, provided that the dose likely to be received by
				the individual while obtaining the samples will not be so great as to require
				monitoring pursuant to Section
				340.520(a)
				of this Part.
6) The test for
				leakage for brachytherapy sources manufactured to contain radium shall be
				capable of detecting an absolute leakage rate of 37 Bq (0.001 µCi) of
				radon-222 in a 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 185
				Bq (0.005 µCi) of a radium daughter which has a half-life greater than 4
				days.
