The "time" can be thousands of years, though - maybe you forgot to mention that? Anyway, I don't claim there is a danger to the US.

- DarkShikari 16y agoLonger-lived isotopes produce proportionally less radiation. There are no fission isotopes with half-lives between ~1e2 and ~1e4 years.
- Tichy 16y agoYeah well, they can still be dangerous. Otherwise, why don't they just wait it out in Fukushima? Atoms are very small, so even tiny amounts of matter contain a lot of them. So even if any single atom only emits radiation every couple of years, a tiny lump of matter can emit radiation more often than every couple of years, because there are so many atoms in it.
