Re: Normal Uranium or Natural Uranium?

All



I can't find a reference, but I think Bob Brown wrote an AECL report at

Chalk River in the 1980's. As I recall, the decay of U-238 dislodges the

atom from the rock crystal latice and hence U-234 is more available.



There is some information in Annex B of UNSCEAR 2000, but I didn't see a

useful reference.
