One cannot assume that because the short term stuff is in the majority that somehow the long term stuff can be 'absorbed' in the decay calculations.JimC wrote:Sure, there is the 20,000 year half life of Plutonium, but the majority of the radioisotopes have much shorter half lives. The combined activity graph approximates a negative exponential curve, with steep initial declines.
The long term stuff must be isolated and treated separately according to it's properties.We are not talking theory or statistics here, but practical treatment of highly dangerous substances.
