The US military sprayed a toxic radioactive chemical over a part of St Louis

The US military sprayed a toxic radioactive chemical over a part of St Louis with 10,000 low income people, 70% of them being children under the age of 12.

Why? They just wanted to do an experiment to test "dispersal patterns and the geographic range of chemical or biological weapons", nothing more.

Instead of using something that is harmless to the test the range and dispersal, they used an actual radioactive bioweapon called Cadmium sulfide, and allowed a bunch of low income children and other people to breath in tons of cadmium sulfide all day every day without warning. They also put additional sprayers on top of buildings and pumped it into populated low income areas.
