Abstract
The basic concern of the safe transport of radioactive material is the protection of persons against ionizing radiation. Radioactive material is the only class of dangerous goods, that gives rise to interaction with the environment during regular transportation without occurrence of any incident. Since the first appearance of the recommendations for the safe transport of radioactive material in 1961, the underlying principle was to exclude high exposures by limiting the dose rate levels at packages and conveyances. These corresponded to the ' permissible doses' ofiCRP at that time. The ALARA (As Low as Reasonably Achievable) or optimization principle was not required in the way it is postulated in present regulations.
