How long is nuclear waste high radioactive? Educator app for Radiation has always been present in the environment and in our bodies. This is why lead aprons and blankets are the most effective shielding material to fight off x-rays and gamma-ray. Although exposure to ionizing radiation carries a risk, it is impossible to completely avoid exposure. The amount of radiation an individual receives is dependant on how close they are to the source. The International Commission on Radiological Protection (ICRP) is responsible for the development of these principles. Mc Graw Hill. ?
