[ RadSafe ] sr90 from noble gases

[John R Johnson]

Norm et al

Sr-90 (halflife ~= 27 years) is the progeny of Rb-90 (halflife ~= 3 minutes)
which is the progeny of Kr-90 (halflife ~= 35 seconds). All 3 are fission
products so the amount of Sr-90 produced from decay will depend on the time
and filtering of that fission gases have.

Guys and gals,

Somewhere I read that sr90 could be produced from the decay of noble gases
emitted from nuke plants. What can you all tell me about this?
