Most U.S. gun owners use lead-based ammunition and primers, and nearly half don’t engage in any post-shooting hygiene behaviors such as changing their clothes or showering, a study found.
I’m not sure that’s as wide of an issue compared to lead being in the gas tank. Then again I don’t know if there were ever studies on fallout from such tests on USA soil.
Also radioactive fallout from nuclear testing (over 1000 nuclear devices in the US) during their early development
