Discover and understand radiation protection*

Radiation protection refers to all measures taken to ensure the protection of humans and their environment from the harmful effects of exposure to ionizing radiation: alpha, beta, gamma and X.

  • Radiations exposure

Some radiations (alpha, beta, gamma and X) are called "ionizing" because they carry enough energy to cause a change in the electrical charge of the atoms they pass through (ionization phenomenon). Exposure corresponds to the interaction of ionizing radiation with matter. Exposure is usually low, but in the event of an accident, for example, people may be exposed to high doses of radiation.

  • Irradiation

External exposure causes external irradiation. It can be controlled according to the duration of exposure, the distance with the source of radiation and the use of protective screens.
A person exposed to an external source of radiation (such as an x-ray) will never carry the slightest trace of radioactivity.

  • Radioactive contamination

Radioactive contamination is often defined as "the undesirable presence of radioactive substances on the surface or inside any medium, including the human body".
Contamination is necessarily the result of the dispersion of a radioactive substance, for example following a careless handling. Radioactive substances are of very diverse origin and may be in solid, liquid or gaseous form.
