Re[2]: French probe nuclear rail shipments

[Ruth Weiner <rfweine@sandia.gov>]

     In the U. S., transportation is regulated by 10 CFR Part 71.  There is 
     external radiation, and in the U. S. these shipments would probably be 
     limited by an external dose rate of 50 mrem/hr one meter from the 
     surface, or perhaps a surface dose rate of 200 mrem/hr.  I don't know 
     how this compares in France.  We did some measurements in the near 
     field, and the dose decreases as 1/r until you are about 4 meters from 
     the container, and as the square of that at longer distances.  "r" is 
     the perpendicular distance of the receptor from the center of the long 
     edge of an essentially cylindrical cask; the dose is smaller at other 
     points.

In a message dated 98-05-09 14:04:09 EDT, S. Perle reports:
     
<< PARIS, May 8 (UPI) _ The French government today launched a full
 inquiry into reports that trains carrying nuclear waste from across 
 Europe to Normandy were contaminated at up to 500 times the normal 
 level.  >>
     
Does anyone have any data as to what  is the"normal level" of contamination of 
these transport cars? It is hard to judge just what is being discussed here 
without some data as to whether they are are talking about contamination level 
or perhaps exposure rate.
