This film tells the story of the Radiation Protection since the discovery of X-rays and radioactivity until today. Radiation protection was built gradually. First, on a principle of limitation until 1950: prevent deterministic effects, which appear above a certain threshold of exposure. Later, during the second part of the 20th century, on a precautionary approach: use radiation only if they are useful and provide a real benefit, and maintain exposures as low as reasonably possible.
