[ RadSafe ] NRC Press Release and suggested PAGs

[John Ahlquist]

As others have stated it would be nice to know the assumptions behind these 
calculations.  I'm surprised that the NRC did not include them or at least have 
a reference to them.  We know nothing about the source term, the plume height, 
the age of the fuel, the type of fuel [MOX?], time of release post shut down, 
etc.  Otherwise, I don't know what to make of these numbers.   Should I use them 
for decision making or not?  We need to understand the numbers to make good 
decisions.  The Japanese people have been traumatized a lot. We don't need to 
throw more confusion into this serious situation.

I would encourage anyone from NRC who reads this list to provide some more 
information.

numerical 
values postulated are sobering...
