These days, the Federal Office of Public Health distributes iodine tablets to the population living close to the Swiss nuclear power plants (NPP). The dispensing of iodine tablets within a radius of, now, fifty kilometres around NPP sites is aimed at protecting the residents from contamination with carcinogenic, radioactive iodine in the event of a severe nuclear accident.To make sure that as little radioactive iodine as possible gets into the environment as a result of a nuclear accident, researchers from the Paul Scherrer Institute PSI have for many years been developing a method that can be used in containment venting filters.

Researchers at the Paul Scherrer Institute (PSI) are currently involved in an international project aimed at reconstructing what happened to the reactor units during the nuclear accident at the Japanese nuclear power station, Fukushima Daiichi in March 2011. In particular, the estimate of the core end-state will help the owner of the damaged plant, the Tokyo Electricity Power Company (TEPCO) to plan the removal of components from the reactor containment and the final decontamination. Besides, the exercise is intended to contribute to further refinement of the computer programs used to perform nuclear accident simulations

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.
