Retention of radioactive iodine in serious NPP accidents
Researchers at the Paul Scherrer Institute [PSI] have developed a highly efficient technique for filtering radioactive iodine. It removes virtually all of the iodine from radioactively contaminated exhaust air before its release into the environment after a meltdown at a damaged nuclear power plant. The process has recently become ready for worldwide use at nuclear power installations, after PSI and the industrial company CCI AG (Balterswil/TG) have signed a licensing agreement for the PSI patented process.
Physicists observe the splitting of an electron inside a solid
An electron has been observed to decay into two separate parts, each carrying a particular property of the electron: a spinon carrying its spin à the property making the electron behave as a tiny compass needle à and an orbiton carrying its orbital moment à which arises from the electron’s motion around the nucleus. These newly created particles, however, cannot leave the material in which they have been produced.
