Answer 1

The greatest significant of nuclear decay is that it proves quantum mechanics, specifically the idea of quantum tunneling. The energy barriers that keep an atomic nucleus together are very high. Ordinarily, it would be essentially impossible for a charged particle in the nucleus to ever get over these walls at room temperature. However, quantum mechanics tells us sometimes particles can "tunnel" through walls over which they cannot climb, and it happens unpredictably, at random intervals, with some average probability in a given time.

That's what happens in nuclear decay. A particle -- for example an alpha particle -- tunnels out of the nucleus. Once it's out, it flies away because of the strong electrostatic repulsion. So the fact that nuclear decay even exists is strong proof of one of the two most significant and strange theories of physics ever devised.

The social implications of using this process are the same as the social implications of using any natural phenomenon. You can use it wisely (to cure cancer) or stupidly (to kill people), or not at all.
