Yeah. Most of the radiological materials used in the USA during
the nuclear boom of the 40s and 50s were dug out of the ground
within a 200 mile radius of Moab. The rock buttes around there
are dotted with old uranium mines, also rich in Cs 137 and Sr 90.
The Bureau of Land Management (aka the Bureau of Livestock and
Mining) has slowly been cementing over the entrances of the mines
for years. People go in there and wander around, not realizing
they're getting a lifetime of radiation in a 2-hour visit and
inhaling concentrations of Radon that make doctors shudder in
horror.
