So what? There is a radioactive beach in south Devon UK. It’s not closed off to the public because it is ‘naturally’ occurring  uranium ore.  Yet, if one had a piece of it in a lab, its counts per minute would require it to be kept in a ‘suitable container’. Makes ones’  Geiger counter sound like an angry box of hornets. Madam Curie got her pitchblende from near by because it was the richest source known at the time and still is the most naturally radioactive place in the whole of Europe. As Michael Cain might say: <i>Not a lot of people know that.</i>  Save perhaps for the people living there.
