Welcome to /c/[email protected] , where fake history is made. Find a historically significant photo, come up with a fake history title, post it, laugh.

The name is a reference to the fact that the pictures should be worth marveling at. This is NOT a place for hardcore pornography. Tasteful nudity is fine as long as it fits within the context of the post (please mark it as NSFW).

Neutrons require similar shielding.

It's possible to block alpha emissions with skin/paper and beta with a sheet of foil, gamma and neutron are scary
