How to shield from gamma rays

WebShields are also used in some reactors to reduce the intensity of gamma rays or neutrons incident on the reactor vessel. This radiation shielding protects the reactor vessel and its internals (e.g.,, the core support barrel) from excessive heating due to gamma-ray absorption fast neutron moderation. WebThe values for the fraction of energy transferred for a given initial gamma ray energy depends on the scattering angle and can range from a minimum value of 0 to a maximum value of nearly 1 for gamma ray energies greater than 10 MeV. In pair production, the gamma ray photon’s energy is used to form an electron-positron pair.
