has some worthwhile reading on these topics.

The amount of actual radioactivity in the environment from the nuclear
industry seems extraordinarily low.

Most of it is short duration stuff, and what gets into us is trivial
compared with the natural background levels.

Personnally I would like to see more research and understanding on
what causes cancer "hot-spots" before we risk raising the level of
background or other radiation.
