This is a good question. Perhaps the answer depends on the country. I would
ask the Canadian trucking associations at

Jade Transportation (http://www.jadetrans.com/aboutus.html)
British Columbia Trucking Association (http://www.bctrucking.com)
Alberta Motor Transport Association (http://www.amta.ca)
Saskatchewan Trucking Association (http://www.sasktrucking.com)
Ontario Trucking Association (http://www.ontruck.org/memberlinks)
Transport Quebec: Trucking
(http://www.mtq.gouv.qc.ca/en/camionnage/index.asp)
Transport Canada 2000 (http://www.transport2000.ca/atlantic/about.html)
Canadian Trucking Alliance (http://www.cantruck.com)
Canadian Trucking Association( http://www.cta.ca/contacts.php)

Regards

John

Subject: [ RadSafe ] Transport Shielding Requirements for Uranium ?



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.
