RE: Radioactive Fossils

[Mike Dupray <dupray@gat.com>]

I may be mistaken, but I believe radioactive fossils are caused by or the
result of uranium salts soaking into the bones over thousands of years.
There are some areas where these deposits can accumulate enough to produce
a 30 mr/hr dose rate. And it is friable. So, it also presents a
contamination problem. I wonder how many diggers and researchers have been
contaminated and how much was ingested?
