By CEA
The CEA’s radiobiology and toxicology research is multidisciplinary and concerns the characterisation of the effects on humans and on the environment of ionising radiation (radiobiology) and radionuclides (nuclear toxicology), and also of nanoparticles (nano-toxicology), in response to their increasing use in energy processes. The radiobiology work being carried out focuses in particular on the consequences for somatic stem cells and germ cells of exposure to low doses of ionising radiation, on individual radiosensitivity, and on new developments in radiotherapy. It contributes to the updating of standards on the radiation protection of workers in the nuclear industry and on the judicious use of medical radiotherapy. In toxicology, the aim is to study what happens to radionuclides, together with their health and environmental impacts, and those of the nanomaterials and chemical compounds used in the technologies developed by the CEA. These studies help to develop well thought-out standards of protection and to devise new methods for remedial action and decorporation.
