Continuous radioactivity monitoring systems. From the pre-history of radioprotection to the future of radioecology.
The first significant quantities of artificial radioactivity appeared in the environment around the end of the 1940s. They were gigantic and their metrology very quickly seemed to be essential for sanitary and military reasons. In the 1950s, the first continuous monitoring systems of "fall out" were created. They were neither automatic nor sensitive and radioprotection of the environment was not a concern only for simple public information. Since then, radioecology, technology and evolution of our mentality have completely modified our way of thinking. Thus, from the 1980s up to the dawn of the new millennium, the gap between the performances of metrology laboratories and certain aspects of direct measurement has almost disappeared. 1986 certainly contributed a lot to the concept of surveillance networks and alarm systems, emphasising that the major advantage of these is the fact that they are operational, the minute before the accident.
