Radiation protection monitoring technology is used to ensure that the dose limit values for nuclear installation employees and the surrounding population are complied with. Employees of nuclear installations must wear personal dosimeters, which are evaluated monthly by accredited bodies such as Suva or the Federal Office of Public Health (FOPH). Alongside the personal dose, the…
Radioactivity is the property exhibited by an unstable atomic nucleus, according to which it spontaneously emits ionising radiation. ENSI is responsible for the protection of the personnel of nuclear installations, the population and the environment against ionising radiation. Further Information News Background articles Documents
Corrigendum to the scientific article “Valid versus invalid radiation cancer risk assessment methods illustrated using Swiss population data”, published on 24 November 2021 in the Journal of Radiological Protection.
ENSI has upgraded its MADUK web application. The MADUK monitoring network is used to monitor the radioactivity around nuclear power plants and the Paul Scherrer Institute (PSI).
Luana Hafner, a specialist in radiological safety at ENSI, has been awarded the “Cousins Award for Young Scientists and Professionals” at the Sixth International Symposium on the System of Radiological Protection, in Vancouver.
Liquid radioactive substances from Swiss nuclear facilities that reach the Aare and Rhine rivers are well below the officially defined emission limits. This is the conclusion reached by ENSI in the Eighth Swiss Report on the Implementation of the OSPAR Recommendation on Radioactive Discharges.
Using data derived from Japanese atomic bomb survivors, previous calculations of the risks of radiation-induced solid tumours overestimate the risk. This is the conclusion of a scientific paper by ENSI employee Luana Hafner. In cooperation with epidemiologists Linda Walsh and Werner Rühm, she presents a model with which these tumour risks can be calculated using…
Although many insights have been gained through radiation biology research, many ambiguities still remain. Nevertheless, ENSI, in cooperation with other international organisations, is working towards closing these knowledge gaps.
Ionising radiation can cause sicknesses. In order to protect the population and personnel working in nuclear installations from these harmful effects, it must be possible to measure radiation doses at any time and as accurately as possible.
