An island in the middle of the South Pacific that is inhabited by 208 civilians, all thinking they are in the Cold War Period, they believe communism is a threat to them, they are all armed with weapons from the 50's - 60's and will engage anything whether they are communist or not. With the exception of children.
Strangely they all emit highly lethal gamma radiation, it is unknown how it is possible due to all inhabitant’s bodies cannot be pierced with any means necessary during autopsy, due to radiation damaging equipment or rendering them useless. Close proximity without proper equipment will result in death in a matter of days, estimate around 1500 - 2000 rads are emitted from them.
I have been thinking of some context for them, but I'm not sure if I want context or not.
