Testing for Leakage or Contamination, Repair, Tagging, Opening, Modification and Replacement of Sealed Sources
Section 350
Section 350.1050 Testing
for Leakage or Contamination
,
Repair, Tagging, Opening, Modification and
Replacement of Sealed Sources
a) The licensee shall permit only persons specifically authorized
by the Agency, the U.S. Nuclear Regulatory Commission, an Agreement State or a
Licensing State to:
1) Replace any sealed source fastened to or contained in a
radiographic device;
2) Test a sealed source for leakage or contamination; or
3) Repair, tag, open or modify any sealed source.
b) An applicant that desires to conduct its own tests for leakage
or contamination shall establish procedures to be followed when testing sealed
sources for leakage or contamination and shall submit a description of such
procedures to the Agency for approval. The description shall include the:
1) Instrumentation to be used;
2) Method of performing the tests; and
3) Pertinent experience of the individual(s) who will perform the
test.
c) Each sealed source shall be tested for leakage or
contamination in accordance with 32 Ill. Adm. Code 340.410. In the absence of
a certificate from a transferor indicating that a test has been made within the
6-month period prior to the transfer, the sealed source shall not be put into
use until tested and the test results confirm that the sealed source is not
leaking or contaminated.
d) An acceptable leak test for sealed sources in the possession
of a radiography licensee would be to test at the nearest accessible point to
the sealed source storage position, or other appropriate measuring point, by a
procedure approved pursuant to subsection (b) of this Section. Records of
tests for leakage or contamination shall be kept in accordance with 32 Ill.
Adm. Code 340.1135.
e) If in accordance with 32 Ill. Adm. Code 340.410 a sealed
source is determined to be leaking or contaminated, the licensee shall
immediately withdraw the equipment involved from use and shall cause it to be
decontaminated and repaired or to be disposed of in accordance with 32 Ill.
Adm. Code 340. Within 5 days after obtaining results of a test showing a
sealed source to be leaking or contaminated, the licensee shall file a report
with the Agency in accordance with 32 Ill. Adm. Code 340.1260.
f) A sealed source that is not fastened to or contained in a
radiographic exposure device shall have permanently attached to it a durable
tag at least 2.54 centimeters (1 inch) square bearing the prescribed radiation
caution symbol in conventional colors, magenta or purple on a yellow
background, and at least the instructions:
DANGER
RADIOACTIVE MATERIAL
DO NOT HANDLE
NOTIFY CIVIL AUTHORITIES IF FOUND
g) Each
exposure device using depleted uranium (DU) shielding and an “S” tube
configuration shall be tested for DU contamination at intervals not to exceed
12 months. The analysis shall be capable of detecting the presence of 185 Bq (0.005
μCi) of radioactive material on the test sample, and shall be performed by
a person specifically authorized by the Agency, the U.S. Nuclear Regulatory
Commission or another Agreement State to perform the analysis. Should the
testing reveal the presence of DU contamination, the exposure device shall be
removed from use until an evaluation of the wear of the S-tube has been made.
Should the evaluation reveal that the S-tube is worn through, the device shall
not be used again. DU shielded devices do not have to be tested for DU
contamination while not in use and in storage. Before using or transferring
the device, however, the device shall be tested for DU contamination, if the
interval of storage exceeds 12 months. A record of the DU leak test shall be
made and kept in units of becquerel (Bq) or microcurie (μCi) and
maintained for inspection by the Agency for 5 years after the records are made
or until the source in storage is removed, whichever time interval is longer.
Licensees shall be in compliance with the DU leak testing requirement of this
subsection beginning October 1, 2004.
