5.4: Ionizing Radiation and Non-ionizing Radiation

Lead is used for shielding in x-ray machines, nuclear power plants, labs, medical facilities, military equipment, and other places where radiation may be encountered. There is great variety in the types of shielding available both to protect people and to shield equipment and experiments. In gamma-spectroscopy for example, lead castles are constructed to shield the probe from environmental radiation. Personal shielding includes lead aprons (such as the familiar garment u… NettetLead is used commonly for two reasons. Being heavy metal it occupies less space; cheaper than other metals like Gold; and significantly absorbs low and medium energy gamma radiation. Materials like concrete can also be used but occupies much space because thick concrete is needed. green rockets try station
