Comprendre ce que sont les rayonnements ionisants

Radiation is a form of energy transmitted through the air. There are many types of radiation that we come across frequently in everyday life, such as heat, light, radio-waves, microwaves and X-rays. Some radiation types, associated with nuclear and atomic processes, have the ability to penetrate material and in doing so cause a process called ionization to happen. These radiation types are known as ionizing radiation; they are the ones commonly referred to just as "radiation" and are associated generally with nuclear and atomic facilities and activities. The source of such radiation is either from radiation generators (such as x-ray machines) or from radioactive material. Radioactive material occurs in nature, but can also be produced artificially - large amounts are produced by the operation of nuclear reactors. Suite sur UNSCEAR...
