Dose monitoring
Individuals who are frequently exposed to radioactivity, either by working in the nuclear industry or elsewhere, regularly wear dosimeters to measure and control the doses absorbed. This worker from the Brennilis demolition plant wears an electronic dosimeter in addition to the legally required strip of dosimetric film. The advantage of the electronic device is that it allows him to check the instantaneous dose absorbed at any given time, as opposed to the average value indicated by the film.
