Arizona Administrative Code › Title 9 - HEALTH SERVICES › Chapter 7 - DEPARTMENT OF HEALTH SERVICES - RADIATION CONTROL › Article 5 - SEALED SOURCE INDUSTRIAL RADIOGRAPHY › Section R9-7-505 - Leak Testing and Replacement of Sealed Sources

Current through Register Vol. 30, No. 28, July 12, 2024
A. A licensee shall ensure that replacement
				of any sealed source fastened to or contained in a radiographic exposure device
				and leak testing of any sealed source is performed by a person authorized to do
				so by the Department, the NRC, or another Agreement State.
B. A licensee shall ensure that opening,
				repairing, or modifying any sealed source is performed by a person specifically
				authorized to do so by the Department, the NRC, or another Agreement
				State.
C. A licensee that uses a
				sealed source shall have the source tested for leakage by a qualified person at
				intervals that do not exceed six months. The person who performs leak testing
				of the source shall use a method approved by the Department, the NRC, or by
				another Agreement State. A wipe sample shall be taken from the nearest
				accessible point to the sealed source where contamination might accumulate. The
				wipe sample shall be analyzed for radioactive contamination. The licensee shall
				ensure that the analysis is capable of detecting the presence of 185 Bq (0.005
				microcurie) of radioactive material on the test sample and a person
				specifically authorized by the Department, the NRC, or another Agreement State
				performs the analysis. The licensee shall maintain records of the leak tests in
				accordance with this Section.
D.
				Unless a sealed source is accompanied by a certificate from the transferor that
				shows that the sealed source has been leak tested within six months before the
				transfer, a licensee shall not use the sealed source until it is tested for
				leakage. A licensee is not required to test a sealed source that is in storage,
				but shall test each sealed source before use or transfer to another person if
				the interval of storage exceeds six months.
E. A licensee shall immediately withdraw
				equipment containing a leaking source from use and have it decontaminated and
				repaired or dispose of the source in accordance with this Chapter. The licensee
				shall file a report with the Director of the Department within five days of any
				test with results that exceed the threshold in this subsection, and describe
				the equipment involved, the test results, and corrective action taken. If a
				leak test conducted under this Section reveals the presence of 185 Bq (0.005
				microcurie) or more of removable radioactive material the Department classifies
				the sealed source as leaking.
F. A
				licensee shall test for DU contamination at intervals that do not to exceed 12
				months a radiographic exposure device that uses depleted uranium (DU) shielding
				and an "S" tube configuration. The licensee shall ensure that the analysis is
				capable of detecting the presence of 185 Bq (0.005 microcuries) of radioactive
				material on the test sample and a person specifically authorized by the
				Department, the NRC, or another Agreement State performs the analysis. If the
				testing reveals the presence of 185 Bq (0.005 microcuries) or more of removable
				DU contamination, the licensee shall remove the exposure device from use until
				an evaluation of the wear on the S-tube is completed. If the evaluation reveals
				that the S-tube is worn through, the licensee shall ensure that the device is
				not used again. The licensee is not required to test for DU contamination if
				the radiographic exposure device is in storage. Before using or transferring
				the radiographic exposure device, the licensee shall test the device for DU
				contamination if the interval of storage exceeds 12 months. The licensee shall
				maintain records of the DU leak test in accordance with subsection
				(G).
G. A licensee shall maintain
				records of leak test results for each sealed source and for each device that
				contains DU. The licensee shall ensure results are in Becquerels (microcuries),
				and retain each record for three years after it is made or until the source is
				removed from storage and tested, whichever is longer.
