Leak testing.



211.842-211.852, 211.990(4)


AUTHORITY: KRS 194.050, 211.090, 211.844


FUNCTION, AND CONFORMITY: The Cabinet for Human Resources is authorized by KRS

211.844 to provide by administrative regulation for the registration and

licensing of the possession or use of sources of ionizing or electronic product

radiation and to regulate the handling and disposal of radioactive waste. This

administrative regulation provides requirements and procedures for the testing

of sealed radioactive sources for leakage and contamination.


      Section 1.

Applicability. This administrative regulation establishes leak testing

procedures for sealed sources.


      Section 2. Tests

for Leakage and Contamination of Sealed Sources. (1) Requirements. Each

licensee possessing or using sealed sources of radioactive material, foil

sources, or plated alpha sources shall have the sources periodically tested for

leakage and contamination as prescribed in this section. Records of these tests

shall be maintained and made available for inspection by the cabinet.

      (2) Method of

testing. Tests for leakage and contamination shall be performed only by persons

specifically authorized to perform the tests by the cabinet, United States

Nuclear Regulatory Commission, or an Agreement State. The test sample shall be

taken from the surface of the source or from the surface of the device in which

the source is stored or mounted and on which one might expect contamination to

accumulate. The test sample shall be analyzed for radioactive contamination and

the test shall be capable of detecting the presence of 0.005 microcurie of

radioactivity on the test sample. The results of the test shall be kept in

units of microcuries and maintained for five (5) years unless otherwise

specified by these administrative regulations or license conditions.

      (3) Interval of

testing. Each sealed source of radioactive material or foil source shall be

tested for leakage and contamination at intervals not to exceed six (6) months.

Each source designed for the purpose of emitting alpha particles shall be

tested at intervals not to exceed three (3) months. In the absence of a

certificate from a transferor indicating that a test has been made prior to the

transfer, the sealed source shall not be put into use until tested. In addition

to the leak test intervals specified in this administrative regulation, the

cabinet may authorize extended leak test intervals for specific sources used in

certain specific applications.

      (4) Leaking or

contaminated sources. If the leak test reveals the presence of 0.005 microcurie

or more of removable contamination, the licensee shall immediately withdraw the

source from use and shall cause it to be decontaminated, repaired, or disposed

of in accordance with the cabinet's radiation administrative regulations. All

equipment which has been in contact with the leaking source shall be checked

for contamination and decontaminated as specified by the cabinet. A report

within five (5) days of the test describing the equipment involved, the test

results and the corrective actions taken shall be filed with: Manager,

Radiation Control, Kentucky Cabinet for Human Resources, 275 East Main Street,

Frankfort, Kentucky 40621.

      (5) Exemptions.

In addition to the requirements of this section, the following sources are

exempted from periodic leak testing:

      (a) Hydrogen-3


      (b) Sources of

radioactive material with a half-life of thirty (30) days or less;

      (c) Sealed

sources of radioactive material in gaseous form;

      (d) Sources of

beta or gamma emitting radioactive material with an activity of 100 microcuries

or less;

      (e) Sources of

alpha emitting radioactive material with an activity of ten (10) microcuries or


      (f) Nickel-63

foil sources of 100 microcuries or less; and

      (g) Plated alpha

sources, other than Californium-252 sources, with an activity of one-tenth

(0.1) microcurie or less. (1 Ky.R. 402; eff. 2-5-75; Am. 2 Ky.R. 479; eff.
