Nuclear binding energy is the energy required to split an atom’s nucleus into protons and neutrons. Mass defect is the difference between the predicted mass and the actual mass of an atom's nucleus. The binding energy of a system can appear as extra mass, which accounts for this difference. Created by Jay. fish curry recipe tamil nadu styleWebAn 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.
