Shielding of Neutron Radiation | Types & Uses | nuclear …
An absorption of neutron (shielding) causes the initiation of certain nuclear reactions (e.g.,, radiative capture or even fission ), accompanied by many other types of radiation. In short, neutrons make matter radioactive, and therefore, we have to shield the other types of radiation with neutrons. See also: Interaction of Neutrons with Matter.
