I've never understood this. If the waste product is radioactive for millions of years then doesn't that mean it's not very radioactive? Wikipedia has this to say: Since radioactive decay follows the half-life rule, the rate of decay is inversely proportional to the duration of decay. In other words, the radiation from a long-lived isotope like iodine-129 will be much less intense than that of a short-lived isotope like iodine-131.¹ So my understanding is radioactive products are dangerous because body takes up the elements and they're either chemically toxic, dangerous because of radioactive decay, or both. So isn't this solved by vitrifying the waste and burying it? Glasses tend to be extremely chemically inert. I'm not convinced the spectre of nuclear waste warrants the paranoia it receives. 1. https://en.wikipedia.org/wiki/Radioactive_waste#Physics https://en.wikipedia.org/wiki/Radioactive_waste#Physics
