The use of depleted uranium munitions has been fiercely debated, with opponents like the International Coalition to Ban Uranium Weapons saying there are dangerous health risks from ingesting or inhaling depleted uranium dust, including cancers and birth defects.
Depleted uranium is not really that radioactive. Everything is technically radioactive eventually though. Depleted uranium is what’s left behind when you seperate the radioactive stuff out. It’s a heavy metal still, so isn’t good for you, but heavy metals will always be involved. Trying to have a war using only healthy, organic, ethically sourced munitions isn’t going to happen.
