Media blackout over “unimaginable” radiation levels detected at Fukushima… MOX fuel melts through reactor floor… half life of 24,000 years
Just something to consider when reading stuff about nuclear fuel, radiation and what not, if something has a very long half life (such as hydrogen which is believed to have a half-life of at least around 10,000,000,000,000,000,000,000,000,000,000 years) it is relatively stable and gives off considerably LESS radiation then something that has a much shorter half life. This basically means that if your dealing with radioactive waste your either dealing with something very hot but decays so rapidly that it will be gone before you have to worry about having to store it somewhere for any length of time or something that doesn't decay so fast you have store it someplace but doesn't give of as much REMs as some of the hotter isotopes.
If you ever heard of salted and/or dirty bombs (which involves knowing the trade off between long half-life and radiation dosages) you might have come across some of the information below:
"Salted versions of both fission and fusion weapons can be made by surrounding the core of the explosive device with a material containing an element that can be converted to a highly radioactive isotope by neutron bombardment. When the bomb explodes, the element absorbs neutrons released by the nuclear reaction, converting it to its radioactive form. The explosion scatters the resulting radioactive material over a wide area, leaving it uninhabitable far longer than an area affected by typical nuclear weapons. In a salted hydrogen bomb, the radiation case around the fusion fuel, which normally is made of some fissionable element, is replaced with a metallic salting element. Salted fission bombs can be made by replacing the neutron reflector between the fissionable core and the explosive layer with a metallic element. The energy yield from a salted weapon is usually lower than from an ordinary weapon of similar size as a consequence of these changes.
The radioactive isotope used for the fallout material would be a high intensity gamma ray emitter, with a half-life long enough that it remains lethal for an extended period. It would also have to have a chemistry that causes it to return to earth as fallout, rather than stay in the atmosphere after being vaporized in the explosion. Another consideration is biological: radioactive isotopes of elements normally taken up by animals as nutrition would pose a special threat to organisms that absorbed them, as their radiation would be delivered from within the body of the organism.
One example of a possible salted bomb would be a cobalt bomb, which would produce the radioactive isotope cobalt-60 (60Co). Other radioactive isotopes that have been suggested for salted bombs include gold-198 (198Au), tantalum-182 (182Ta) and zinc-65 (65Zn). Sodium-24 has also been proposed as a salting agent."
I don't know exactly what is happening at Fukushima but I'm pretty sure that it is no where near as the effects if someone set off a salted nuclear weapon or even a dirty bomb ; although since there has been much testing of such weapons it is hard to know for sure what there effects might be.
