Re: CS-137 in animals

John, 
 
Strontium-90 and cesium-137 are routinely detected in environmental samples in 
the environs of nuclear power plants.  However, if you plot historical data 
you will see that the inventory of strontium and cesium is decreasing with 
time.  The fact that the concentrations are decreasing, supports the rationale 
that these isotopes are due to fallout from past atmospheric nuclear weapons 
testing.  If you send me your FAX number I will send you graphs illustrating 
this trend in milk and sediment samples.

     Group: Is CS-137 left over from the above ground weapons 
     testing?

     "ENVIRONMENTAL GROUP ASKS HUNTERS TO SEND DEER PARTS"
     BOSTON GLOBE ONLINE, 11/4/96, Associated Press
     
     The Wiscasset, ME-based Friends of the Coast on Monday told 
     hunters that it would pay them $5 apiece for parts of deer 
     caught near the Maine Yankee nuclear power plant so the 
     remains can be tested for "man-made radioactive pollution."
     
     In a similar effort last year, the group received one deer. 
     Ken Gray, spokesperson for the group, said that deer, taken 
     4.7 miles downwind from the plant, was found to contain 
     Cesium 137, a radioactive isotope found in nuclear plants 
     and weapons.
     
     But Philip Haines of the state Bureau of Health denied a 
     link between the Cesium 137 in the deer and the power plant. 
     Haines:  "There is certainly no indication to us that it had 
     anything to do with the plant."  Haines said the state, 
     which paid for last year's deer testing,  is interested in 
     the latest research effort, but he added that comparable 
     studies need to be done on deer from other parts of the 
     state.
