[ RadSafe ] Long lived isotope/particle specific activity

[Jerry Cohen]

Doug.
 Perhaps I am dense, or maybe just arithmatically handicapped, so please 
clarify: [1] what is the specific activity of a stable isotope, [2] how do you 
quantitatively express "risk magnitude", and [3] what is RDD ???

A bit of arithmetic calculating the mass specific activity for the whole
range of isotopes, stable and unstable, might lead to some understanding
of risk magnitudes - as from RDD.

Who fails to do arithmetic is doomed, not least to nonsense.
