Radioecology — Site surveys

In situ studies make it possible to observe levels of radioactivity in the environment, and to track them in space and time as a function of changes in the various source terms: fallout from atmospheric tests, discharges, etc. The results help to raise questions about how pollutants are transferred. The results help to raise questions about how pollutants are transferred, which we will attempt to resolve through laboratory experiments. Field work is used to validate the models developed.

Taken together, these studies make it possible to quantify the radioecological impact of radionuclides in the environment. This is the case, for example, in the immediate vicinity of nuclear facilities; but it is also necessary to explore more distant zones which, because of their ecological characteristics, may be places where radioelements accumulate.
