[ RadSafe ] "Toxic strontium" --- let's all panic (again).

[Steven Dapra]

June 15

         Point well made, and well taken.

         How likely is it that anyone will drink 10 Sv worth of 
ground water?  How did this Sr-90 get into the ground water so 
quickly?  Is it from the reactor, or is it from bomb testing 
fallout?  Had any of this water undergone routine testing before the 
tsunami hit?  What is the rad history of the aquifers?
