Ohio Admin. Code 3701:1-48-09 - Leak testing and replacement of sealed sources
(A) The replacement
of any sealed source fastened to or contained in a radiographic exposure device
and leak testing of any sealed source must be performed by persons authorized
by the director, the United States nuclear regulatory commission, or an
agreement state to do so.
(B) The
opening, repair, or modification of any sealed source must be performed by
persons specifically authorized by the director, the United States nuclear
regulatory commission, or an agreement state to do so.
(C)
(1)
Each licensee who uses a sealed source shall have the source tested for leakage
at intervals not to exceed six months. The leak testing of the source must be
performed using a method approved by the department
director ,
the United States nuclear regulatory commission or by an agreement state. The
wipe sample should be taken from the nearest accessible point to the sealed
source where contamination might accumulate. The wipe sample must be analyzed
for radioactive contamination. The analysis must be capable of detecting the
presence of one hundred eighty-five becquerels ( 0.005 microcurie) of
radioactive material on the test sample and must be performed by a person
specifically authorized by the director, the United States nuclear regulatory
commission, or an agreement state to perform the analysis.
(2) The licensee shall maintain records of
the leak tests in accordance with paragraph (D) of rule
3701:1-48-23
of the Administrative Code.
(3)
Unless a sealed source is accompanied by a certificate from the transferor that
shows that it has been leak tested within six months before the transfer, it
may not be used by the licensee until tested for leakage. Sealed sources that
are in storage and not in use do not require leak testing, but must be tested
before use or transfer to another person if the interval of storage exceeds six
months.
(D) Any test
conducted pursuant to paragraph (C) of this rule which reveals the presence of
one hundred eighty-five becquerels ( 0.005 microcurie) or more of removable
radioactive material must be considered evidence that the sealed source is
leaking. The licensee shall immediately withdraw the equipment involved from
use and shall have it decontaminated and repaired or disposed of in accordance
with department rules. A report must be filed with the
department
director , within five days of any test with results
that exceed the threshold in this paragraph, describing the equipment involved,
the test results, and the corrective action taken.
(E) Each exposure device using depleted
uranium shielding and an S-tube configuration must be tested for depleted
uranium contamination at intervals not to exceed twelve months. The analysis
must be capable of detecting the presence of one hundred eighty-five becquerels
( 0.005 microcurie) of radioactive material on the test sample and must be
performed by a person specifically authorized by the director, the United
States nuclear regulatory commission or an agreement state to perform the
analysis. Should such testing reveal the presence of one hundred eighty-five
becquerels ( 0.005 microcurie) or more of removable depleted uranium
contamination, the exposure device must 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 may not be used again. Depleted uranium
shielded devices do not have to be tested for depleted uranium contamination
while in storage and not in use. Before using or transferring such a device,
however, the device must be tested for depleted uranium contamination, if the
interval of storage has exceeded twelve months. A record of the depleted
uranium leak-test must be made in accordance with paragraph (D) of rule
3701:1-48-23
of the Administrative Code.
