The Effect of Lead Doped with Sodium Chloride and Iron on the Attenuation of Gamma Ray Radiation Source

In this work a weak radioactive source was used, and different thickness of ordinary concrete clad with lead and concrete containing sodium chloride salts covered with lead in order to study how radiation is attenuated by different materials of different thicknesses. This is important knowledge for those who design radiation shields, to protect the human organism, it should be in controlled situations; where radiation is employed to perform desired tasks, such as medicine, or nuclear power plants, so unwanted exposure must be avoided. It may also be the necessary knowledge to protect human life from nuclear explosions in a situation of warfare
