Regulation 27 Carriage in bulk
Subject to paragraphs (2) and (3), no person shall cause or permit to be carried any radioactive material in bulk.
LSA-I may be carried in bulk provided—
in the case of natural ores it is carried under exclusive use; or
in any other case, it is carried in such a way as to ensure that there can be no escape of contents from the freight container or wagon in which it is being carried and no loss of shielding.
SCO-I may be carried in bulk provided—
it is carried in a freight container or wagon in such a way as to ensure that there can be no escape of contents and no loss of shielding;
where the contamination on the accessible and inaccessible surfaces of the radioactive material is greater than 4 Bq/cm2 for beta and gamma emitters and low toxicity alpha emitters or 0·4 Bq/cm2 for all other alpha emitters, the material is carried under exclusive use; and
where it is suspected that non-fixed contamination on inaccessible surfaces of the radioactive material is greater than 4 Bq/cm2 for beta and gamma emitters and low toxicity alpha emitters or 0·4 Bq/cm2 for all other alpha emitters, measures are taken to ensure that the material is not released into the freight container or wagon.
