In addition to knowing that nuclear energy could be used for a source for ALL our power needs it might be useful for people not familiar to nuclear power technology to know of something called radiation hormesis.
The theory can be a little complicated but it is basically the idea IN LOW DOSAGES RADIATION MAY ACTUALLY BE GOOD FOR YOU. I know that it sounds really crazy but data collected by people that are exposed to low dosages suggests instead of it being always being harmful statistically speaking it seems to make people less vulnerable to other things.
Again I don't have the medical background to make any determination as to whether it is real or just some crackpot theory (although it is partially believed by the people in nuclear power industry itself) there is some evidence that very small dosages have a completely negligible effect or at times might even help certain people.
If it all sounds crazy stop and consider all the various other potentially life threatening toxins you are exposed to day in and day out (such as caffeine, germs,etc) and realize how much more dangerous it would be to live in a bubble never exposed to ANY of them. Without anything to fight our immune systems weaken and if (or I should say when) they are exposed to toxins and germs again there is a good chance they won't have enough resistance to deal with them.
Here is a small passage from the wiki page
"Radiation hormesis (also called radiation homeostasis) is the hypothesis that low doses of ionizing radiation (within the region of and just above natural background levels) are beneficial, stimulating the activation of repair mechanisms that protect against disease, that are not activated in absence of ionizing radiation. The reserve repair mechanisms are hypothesized to be sufficiently effective when stimulated as to not only cancel the detrimental effects of ionizing radiation but also inhibit disease not related to radiation exposure (see hormesis).This counter-intuitive hypothesis has captured the attention of scientists and public alike in recent years"
..and some other links:
Also a small problem radiation hormesis could create if it did exist is that it could screw up statistical data when considering what level of radiation is bad for you. If radiation helped some people and hurt (at certain dosages ) it might create the perception that there is an overall 'zero' or 'near zero' threat for people at the smaller dosage: such as 1 RAD/REM to 20 RAD/REM. At any rate it creates (if it exist) a problem for the people that think there is a linear relationship between radiation and the health hazards from it.
