Are everyone who think so complete dumbs or idiots or what?It's NOT increases radioactivity on planet surface or anywhere.Like saying that golfstream produces radioactivity because there's lots of uranium and other isotopes in water moved by it. Nuclear plant also not increases radioactivity for infinite time,it increases radioactivity for "short" time of several throusands of years. Assume we have isotope with halflife of 50 years.Uranium half-life is 5*10^9 years.That waste is 10^8 times more radioactive.To fall to uranium level,more than 24 half-life periods must pass(2^3=8 ,bit lesser than 10).It's 1200 years. Other isotope of 500 years are 1^7 times more radioactive and need 21 half-lifes,10_000 years to rearch uranium level. > > Some gases from things like radon gas > > otherwise trapped in the coal beds, and other solid radiation sources > > like potassium-40 that is in the fly ash, concentrated by plants in > > areas where the fly ash eventually settles and then found in the food > > supply.

Only idiots think so.Many peoples died after Chernobil,and that was relatively small plant,only one reactor have been melted,and only sevral precents of isotopes was spreaded in the gaseous form,wind moved in opposite direction to town(forest was die at direction of wind,even that plants are quite resistant,many times more resistant than humans).Strange,but peoples that like += also like radioactivity.Should be correlation...mutation.... > It's just more > concentrated in the nuclear waste -- but that's an advantage, because > that makes it much easier to manage.

The sheer ignorance of > people who parrot this one has always amazed me. First of all, > chemical waste isn't dangerous for just "hundreds of thousands of > years," it is dangerous *forever*. It has an *infinite* halflife. Not.It have relatively small halflife.Biologically dangerous _molecular_ waste should react with biopolymers,that's happen and bacteries could clean that waste relatively fast,there's no exponential halflife.When dangerous elements(like lead) are spreaded,it again does not increases concentration on surface. > A > long halflife means weak radioactive emissions.

Please reply to _that_: Nuclear bomb are equivalent to several kg's of waste. Do you want nuclear war? Or for you there's no difference between nuclear war and non-radioactive weapons because they works like coal-fired power? Many peoples die due to several microgramms of waste they got after Chirosima,or what,not?!?!?!? Are we again need small nuclear war to become more-or-less careful?
