Radiation Protection

Radiation measuring device that measures the pulses generated in a counter tube and displays the number of pulses per second.

Radiation protection serves to protect personnel, the population and the surroundings of nuclear installations against ionising radiation.

ENSI deals with occupational radiological protection, dosimetry, radiation measurement systems, radioactive emissions and environmental monitoring, as well as with the radiological impact of accidents.

    Radiation Biology (5/5): Current research in radiation biology

    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.

    Radiation Biology (4/5): How ionising radiation is measured

    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.

    Radiation Biology (3/5): Low doses and their damage potential

    There is no question in radiation biology that the severity of sickness increases at high doses. Nevertheless, it is important when considering everyday radiation protection to be able to estimate the risk of a mutation of the genetic material, and thus the risk of cancer, even in the low dose range.
