Radiation Protection

Radiation protection serves the purpose of protecting the staff, the population and the areas surrounding nuclear plants against ionising radiation. The key aspects here are radiation measurement technology and radioanalytical work.

Background Articles

Radiological protection always begins by avoiding unnecessary exposure. One of the guiding principles behind radiological protection is therefore that the radiation burden on people should be kept as low as is reasonably achievable.

Development and Research Work in the Field of Radiation Measurement Technology: this project deals with the verification and calibration of dosimetry systems and radiation measurement instruments. On the one hand, importance attaches to personal dosimetry, i.e. the measurement of the outer and inner radiation exposure for people. This field also covers measurements of the release […]

In this 9th Annual Report, ENSI focusses on radiological protection in Swiss nuclear facilities. The average individual dose has changed little compared with previous years. At 0.7 mSv, it is significantly below the limit both for persons exposed to radiation during their work (20 mSv) and the annual average rate of exposure for the population […]

This Annual Report of ENSI deals solely with radiological protection in nuclear facilities in Switzerland: Section A covers both exposure rates for staff and individual job rates whereas Section B deals with releases from nuclear facilities and the monitoring of radioactivity in their immediate vicinity. Compared with previous years, there was little change in either […]

Nine months after the disaster at the Fukushima nuclear power plant, Japan is working to contain radiation exposure in the region of the accident. The challenges confronting the country in this endeavour are shown by the new ENSI report on the radiological effects of the accident on 11 March 2011. A significant discharge of radioactivity […]

On January 1st 2009, HSK became ENSI, the Swiss Federal Nuclear Safety Inspectorate and at the same time the new body became independent of the Swiss Federal Office of Energy. However, the remit of the new regulatory body remains unchanged. ENSI continues to monitor ionising radiation and radioactivity in Swiss nuclear facilities and their immediate […]

2008 was a very special year for HSK – in fact it was its last. On 1 January 2009, HSK became ENSI, the Swiss Federal Nuclear Safety Inspectorate. Further information on the change can be found in the Surveillance Report of ENSI for 2008. To simplify matters for the reader, the new designation of ENSI […]

Dans ce rapport annuel 2005, la DSN donne une vue d’ensemble de la radioprotection dans son domaine de surveillance. Jusqu’à présent, les thèmes qui le constituent étaient abordés et traités dans le rapport de dosimétrie et dans celui sur la radioactivité de l’environnement, destinés tous deux à l’Office fédéral de la santé publique et élaborés […]
