Regulation 5

the maximum radiation level at a distance of 1 m from the external surfaces of the package, overpack, tank, freight container, or unpackaged LSA-I and SCO-I shall first be determined, and —

where the radiation level is determined in units of millisievert per hour, the value determined shall be multiplied by 100; and

for uranium and thorium ores and concentrates, the maximum radiation level at any point 1 m from the external surface of the load may be taken as —0.4 mSv/h for ores and physical concentrates of uranium and thorium; 0.3 mSv/h for chemical concentrates of thorium; and 0.02 mSv/hfor chemical concentrates of uranium, other than uranium hexafluoride;

for tanks, freight containers and unpackaged LSA-I and SCO-I of such size specified in the first column of Table 4 of the Third Schedule, the value determined in sub-paragraph (a) shall be multiplied by the appropriate multiplication factor specified in relation thereto in the second column of that Table; and

the figure obtained in sub-paragraphs (a) and (b) shall be rounded up to the first decimal place, except that a value of 0.05 or less may be considered as zero.
