Abstract
Among the revised points in the 1985 edition of the IAEA Regulations, the acceptance criteria for shielding integrity after testing at normal conditions of transport is one of the most important points in designing and testing package. The sentence • It would prevent any increase of the maximum radiation level\" that appears in the 1973 edition has been changed to •It would prevent more than a 20% increase in the radiation level at any external surface\" . With respect to the new requirements in the 1985 edition, the necessity of considering any external surface and the meaning of a 20% increase are being discussed worldwide. In this paper we discuss the radi6logical meaning of this requirement through a radiological approach and propose an alternative concept.
