Areal dosimetry at research centres.

Radiation protection regulations apply to research centres and nuclear facilities alike. Radiological dose resulting from their activities is strictly limited by law; therefore, it has to be monitored. As a supplement to the personal dosimetry systems (mainly for the work force classified as occupationally exposed), areal dosimetry is an efficient surveillance tool. Serving as an example, the concept of areal dosimetry applied at the Paul Scherrer Institut is presented.
