[ RadSafe ] evacuation: where and how long?

[Dan W McCarn]

Hi Karen:

I am hardly an expert, but there is a significant distribution of 'hot
particles' in the exclusion zone. 

But onto other issues: For the wet-deposition material, Cs & Sr have a very
high selectivity for adsorption sites onto clays and especially decaying
organic matter with a high cation-exchange capacity (CEC).  The soils in the
forest form a thick organic humus zone, which traps the Cs-137 & Sr-90.
