Halving Half Lives

An anonymous reader writes "PhysicsWeb is reporting that German scientists may have found a way to significantly reduce the radioactive decay time of nuclear waste. This could render the waste harmless in just tens of years and make disposal much less difficult as opposed to current standards. From the article: 'Their proposed technique - which involves slashing the half-life of an alpha emitter by embedding it in a metal and cooling the metal to a few degrees kelvin - could therefore avoid the need to bury nuclear waste in deep repositories, a hugely expensive and politically difficult process. But other researchers are skeptical and believe that the technique contradicts well-established theory as well as experiment.'"

    The Marianas Trench? Are you insane, man? Don't you remember what happened last time we dumped nukes in the Pacific?

    In order to get the radiation down to safe levels, you have to out-radiate everything up to that level. Same radiation, doesn't matter if it takes the normal amount of time or less.

    Actually it matters quite a bit. There are plenty of places where all that radiation would be hardly noticed, and if the timescale is lessened to something managable by today's governments, we will be able to avoid the monumental task of warning future generations.

    I'd say that's quite a big win, if this pans out.

    Not a problem anymore. Just store the spent fuel near the Jewish Anti-Defamation League and give Mel Gibson a few drinks and have a news reporter standing by. The chill from the ADL will zap that spent fuel down to absolute zero in no time.

    nuclear scientists say this works and can happen, and have done experiments.

    but Slashdot user swchrad (312009) disagrees! Well shit, guess we can abandon that idea then.

    Getting even small amounts of matter within a few degrees of absolute zero takes a lot of energy.

    Even worse, what if the nuclear waste explodes and triggers a fusion reaction on the surface of the sun. How much trouble would we be then?
