# The Radioactive Material (Road Transport) (Great Britain) Regulations 1996, Regulation 21: Contamination levels


(1) The non-fixed contamination on the external surfaces of package shall be kept as low as reasonably practicable and, under conditions likely to be encountered in routine transport, shall not exceed the levels spedified in Table III of Schedule 36.
(2) Except as provided in paragraph (5), the level of non-fixed contamination on the external and the internal surfaces of overpacks, freight containers and tanks shall not exceed the limits specified in Table III of Schedule 36.
(3) A conveyance and equipment used routinely for the transport of radioactive material shall be periodically checked to determine the level of contamination. The frequency of such checks shall be related to the likelihood of contamination and the extent to which radioactive material is transported.
(4) Except as provided in paragraph (5), any conveyance, or equipment, or part thereof which has become contaminated above the limits specified in Table III of Schedule 36 or which shows a radiation level in excess of 5 μ Sv/h, in the course of the transport of radioactive material shall be decontaminated as soon as possible and shall not be re-used unless the non-fixed radioactive contamination does not exceed the levels specified in Table III of Schedule 36, and the radiation level resulting from the fixed contamination on surfaces after decontamination is less than 5 μ Sv/h.
(5) An overpack, freight container or conveyance dedicated to the transport of LSA material or SCO under exclusive use shall be excepted from the requirements of paragraphs (2) and (4) solely with regard to its internal surfaces and only for as long as it remains under that specific exclusive use.
