Section He-P 4001.05 - Tests(a) Each licensee and registrant shall perform, pursuant to instructions from DHHS/RHS, or shall permit DHHS/RHS to perform, tests which will assist DHHS/RHS in determining the licensee's or registrant's compliance with these rules, including tests of: (1) Sources of radiation;(2) Facilities where sources of radiation are utilized or stored;(3) Radiation detection and monitoring instruments; and(4) Other equipment and devices used in connection with the utilization or storage of licensed or registered sources of radiation.(b) The licensee in possession of any sealed source shall ensure that: (1) Each sealed source, except as specified in He-P 4001.05(c), 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 6 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 12 months, except those as specified in He-P 4034.10 and He-P 4035.21;(3) Each sealed source that is designed to emit alpha particles is tested for leakage or contamination at intervals not to exceed 3 months;(4) Each sealed source that is required to be tested for leakage or contamination, that might have been damaged or might be leaking, is tested for leakage and contamination before further use;(5) Tests for leakage for all sealed sources, except brachytherapy sources manufactured to contain radium, are capable of detecting the presence of 185 Bq (0.005 mCi) of radioactive material on a test sample which is taken from the sealed source or taken from the surfaces of the container in which the sealed source is stored or mounted and at the nearest accessible point to the sealed source where contamination might accumulate, and for a sealed source contained in a device, test samples are obtained when the source is in the "off" position;(6) Tests for leakage of sealed sources and Brachytherapy sources and their associated requirements are specified in He-P 4035.21;(7) Tests for contamination from radium daughters are taken on the interior surface of brachytherapy source storage containers and are capable of detecting the presence of 185 Bq (0.005 ?Ci) of a radium daughter which has a half-life greater than 4 days; and(8) Tests for leakage or contamination are performed using a leak test kit or method approved by DHHS/RHS.(c) A licensee shall not be required to 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 30 days;(2) Sealed sources containing only radioactive material as a gas;(3) Sealed sources containing 3.7 MBq (100 mCi) or less of beta or photon-emitting material or 370 kBq (10 µCi) 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, except teletherapy and brachytherapy sources, which are stored, not being used and identified as in storage.(d) The licensee shall, however, test each such sealed source in He-P 4001.05(c)(6) for leakage or contamination and receive the test results: (1) At intervals no greater than 3 years; and(2) Before any use or transfer unless the source has been tested for leakage or contamination within 6 months before the date of use or transfer.(e) Tests for leakage or contamination from sealed sources shall be performed by persons specifically licensed by DHHS/RHS, an agreement state, a licensing state, or the U.S. Nuclear Regulatory Commission to perform such services.(f) Test results shall be kept in units of Becquerel or microcurie and maintained for inspection by DHHS/RHS for 5 years from date of test.(g) The following shall be considered evidence that a sealed source is leaking: (1) The presence of 185 Bq (0.005 µCi) or more of removable contamination on any test sample;(2) Leakage of 37 Bq (0.001 µCi) of radon-222 per 24 hours for brachytherapy sources manufactured to contain radium; or(3) The presence of removable contamination resulting from the decay of 185 Bq (0.005 µCi) or more of radium.(h) The licensee shall immediately withdraw a leaking sealed source from use and shall take action in accordance with He-P 4003.05(i) to prevent the spread of contamination.(i) If a sealed source is leaking, the licensee shall:(1) Decontaminate the facility and source in accordance with He-P 4021.20, and dispose of the leaking source in accordance with He-P 4023; or(2) Decontaminate the facility and source in accordance with He-P 4021.20, and have the source repaired by a person specifically licensed to perform this service.(j) Reports of test results for leaking or contaminated sealed sources shall be made pursuant to He-P 4021.19.N.H. Admin. Code § He-P 4001.05
