Ohio Admin. Code 3701:1-38-24 - Testing for leakage or contamination of sealed sources
(A) The licensee in
possession of any sealed source not subject to the testing requirements of rule
3701:1-46-05,
3701:1-48-09,
3701:1-49-07,
3701:1-52-22,
or
3701:1-58-27
of the Administrative Code, shall assure that:
(1) Each sealed source, except as specified
in paragraph (B) of this rule, 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 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 months or at alternative intervals as specified in the sealed
source and device registry sheet;
(3) Each sealed source that is designed to
emit alpha particles is tested for leakage or contamination at intervals not to
exceed three months or at alternative intervals as specified in the sealed
source and device registry sheet;
(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
shall be capable of detecting the presence of one hundred eighty-five
becquerels ( 0.005 microcurie) 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;
(B) A licensee need not perform
tests for leakage or contamination on the following sealed sources:
(1) Sealed sources containing only
radioactive material with a half-life of less than thirty days;
(2) Sealed sources containing only
radioactive material as a gas;
(3)
Sealed sources containing 3.7 megabecquerels (one hundred microcuries) or less
of beta or photon emitting material or three hundred seventy kilobecquerels
(ten microcuries) or less of alpha-emitting material;
(4) Sealed sources containing only
hydrogen-3;
(5) Seeds of
iridium-192 encased in nylon ribbon; and
(6) Sealed sources which are stored, not
being used and identified as in storage. The licensee shall, however, test each
such sealed source for leakage or contamination and receive the test results
before any use or transfer unless it has been tested for leakage or
contamination within six months before the date of use or transfer.
(C) Tests for leakage or
contamination from sealed sources shall be performed by persons specifically
authorized by the director, an agreement state, or the United States nuclear
regulatory commission to perform such services.
(D) Test results shall be kept in units of
becquerel or microcurie and maintained for inspection by the director. Records
of test results for sealed sources shall be made pursuant to paragraph (E) of
rule
3701:1-38-20 of the
Administrative Code.
(E) A sealed
source shall be considered to be leaking if the presence of one hundred
eighty-five becquerels ( 0.005 microcurie) or more of removable contamination
on any test sample is identified.
(F) The licensee shall immediately withdraw a
leaking sealed source from use and shall take action to prevent the spread of
contamination. The leaking sealed source shall be repaired or disposed of in
accordance with this chapter.
(G)
Reports of test results for leaking or contaminated sealed sources shall be
made pursuant to paragraph (F) of rule
3701:1-38-21 of the
Administrative Code.
