I know there is background radiation everywhere, but what would be the safe exposure levels from a contact nuclear explosion on sand? All the Democrats make it sound like it would be tens of thousands of years. I would like to know the real number for a ground burst.

The half-life of Uranium is 93 years. Supposedly it is ‘safe’ after 93 years.
