125. The carrier shall ensure that the non-fixed contamination of a conveyance or equipment or part thereof does not exceed 4 Bq/cm2 for beta emitter, gamma emitter and low toxicity alpha emitters, and 0.4 Bq/cm2 for all other alpha emitters, and the dose rate on any surface resulting from fixed contamination does not exceed 5 µSv/h.
126. Any conveyance or equipment or part thereof which has become contaminated above the limits specified in Article 125 or whose dose rate exceeds 5 µSv/h shall not be reused unless it is decontaminated by a qualified person and the residual dose rate on any surface resulting from fixed contamination after decontamination does not exceed 5 µSv/h.
127. A conveyance or equipment used regularly for the transport of radioactive material or nuclear material shall be periodically checked to determine the level of contamination and the frequency of such checks shall be related to the likelihood of contamination.
128. The dose rate under conditions likely to be encountered in the normal conditions of transport shall not exceed 2 mSv/h at any point on, and 0.1 mSv/h at 2 m from the external surface of the conveyance.
129. Article 125 shall not apply to a freight container, tank, intermediate bulk container or conveyance dedicated to the transport of unpackaged radioactive material under exclusive use.
