OT Nuclear waste.

[harryagain]

You really are a shit-fer-brains. You never read the orginal post did you?

"Because some radioactive species have half-lives longer than one million years, even very low container leakage and radionuclide migration rates must be taken into account.[30] Moreover, it may require more than one half-life until some nuclear materials lose enough radioactivity to no longer be lethal to living organisms. A 1983 review of the Swedish radioactive waste disposal program by the National Academy of Sciences found that country?s estimate of several hundred thousand years?perhaps up to one million years?being necessary for waste isolation ?fully justified.?[31]"

Plus.

You really ARE brain dead. Nuclear waste contains many elements.

Thereby obviating the need for lighting and reducing CO2. Win- Win.

You have read that haven't you? Including the bit that says "Radionuclides such as 129I or 131I, may be highly radioactive, or very long-lived, but they cannot be both." So you now agree with what we have been telling you for years!

[dennis]

Name one material with a one million year half life that is more radioactive than carbon 14 which is found in you. It decays about 20,000 times more than a one million year half life element in case you don't know.

[Tim Streater]

In the case of I131, of all that which existed at the time of the tsunami, not a single atom exists today. It's all decayed.

[dennis]

It can't have, its highly radioactive and needs to be stored for a million years, just ask our expert harry.

[Fredxxx]

Half life of 8 days.

So 4 years would give you 10^-55 of the amount started out.

Even Harry would be comfortable with that.

[Chris Hogg]

It's also good for absorbing cations (pron. cat-ions) if there should be any leaks, as it has a high cation exchange capacity. Montmorillonite (bentonite), the clay much used for cat litter, is particularly good. See

[dennis]

But harry, you are more radioactive (shorter half life of ~6000 years for c14) than waste with a half life of a million years so that means we have to bury you in a hermetically sealed safe storage area for a million years. Its written by idiots like you that don't understand that long half lives *must* mean lower radioactivity. I bet you don't worry about sleeping next to your partner despite the fact you are irradiating them.

[dennis]

Because some of it has half lives of around 50 years so it will take about a thousand years to decay enough to be safe, not millions! Or you could burn it in a suitable reactor.

You think harry has a partner?

True, but not the reason. The reason is that there are a class of radionuclides whose half lives are medium - tens and hundreds of years - which makes them both long lived and somewhat dangerous. Not very, but somewhat.

Strontium 90 and Caesium 137 where the bugaboos of our youth, for example.

[harryagain]

Ah. Moving the goals posts. Still drivelling on.

[dennis]

So you can't give a sensible answer then.

[Tim Streater]

Of course he can't, because he knows f*ck-all about radioactivity or what it is. All he knows is that radioactive stuff is "lethal for millions of years" and trots this mantra out as a stock response to anything.

[harryagain]

And you have retard level comprehension. ability.
