Depleted uranium is actually the less radiative byproduct after using a centrifuge to skim the U-235 isotope. It’s 50% denser than lead and used on tanks. Dirt

Depleted uranium is actually the less radiative byproduct after using a centrifuge to skim the U-235 isotope. It’s 50% denser than lead and used on tanks. Dirty bombs are more likely the ultra radioactive by products of fission. They might not kill much but the radionucleotide spread can render a city center uninhabitable for centuries!
