Obama giving go ahead for Georgia nuke

Ummmm...most fission fragments are Beta emitters, Gamma emitters, or Neutron emitters. There are very few Alpha emitters below Lead (Pb). Cesium and Strontium both emit high energy betas, but, so long as they don't get internalized, are relatively harmless external to the body.

Yeah, I was thinking all the particles, and writing alpha...

And the reason for the cooling off period is two fold, to allow the short lived isotopes to decay away while getting read of excess residual heat (nuclear waste makes a great space heater... :whistling:).

So, in the right environment we would be able to capture the excess heat during the cooling period as well.

And as to most active, it doesn't even exist before the "waste" is removed from the reactor as it takes several weeks for the fuel removal/addition to take place. Typically the reactor is shutdown for a 3 month period (usually when electricty is least needed for three months) and for the first month and half, the fuel is cooling in the reactor itself, this means that any waste with a 7 day or lower half life is gone by the time the waste is removed.

:nod: I figured as much.
