quote:Originally posted by Hadriani came asross this waht do you think?A 360 J laser pulse transmutes an isotope with a half-life of 15.7 million years into a lighter isotope with a half-life of just 25 minutes.One of the biggest challenges facing the nuclear industry today is the storage and disposal of waste that will remain radioactive for millions of years. One approach to this problem involves bombarding the waste with neutrons to speed up the decay of long-lived isotopes into nuclei with much shorter half-lives. However, physicists in the UK and Germany have now demonstrated a new laser-driven approach to "transmutation" by converting iodine-129, which has a half-life of 15.7 million years, into iodine-128. The half-life of this lighter isotope is just 25 minutes (J. Phys. D to be published). http://optics.org/articles/news/9/8/12/1
