[ RadSafe ] Transport Shielding Requirements for Uranium ?

[Leo M. Lowe]

Uranium ore and physical concentrates of such ores are classified as LSA-I 
in the IAEA transport regulations (TS-R-1), which means that they can be 
shipped in regular  IP-1 packages, or unpackaged if shipped under exclusive 
use.  However, high grade ores and physical concentrates can exhibit 
elevated radiation levels, in the order of 0.5 mSv/h or higher at 1 meter 
distance [TS-R-1, para. 526(c) suggests using 0.4 mSv/h at 1 m].

Since the maximum radiation levels for road or rail vehicles for 
consignments under exclusive use  is 0.1 mSv/h at 2 m from the sides of the 
vehicle [TS-R-1 para.572{c)], does this mean that such ores and 
concentrates must be shielded when transported?  I wasn't aware that this 
was a requirement for such materials.
