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).

Isn't there a suit that can protect from radioactivity? Whats the point of the suit if the user gets fucked either way?

No, there's nothing human+portable that will provide enough protection for it to be worthwhile:

Unlike charged particles, a certain percentage of gammas will always make it through the absorber, and it is useful to consider the half-value thickness of a given absorbing material for the gamma ray energies of interest.

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
