Shielding

Abstract

Adequate shielding of neutrons and associated gamma-rays is of importance from viewpoints of the radiation safety of researchers and good experimental data taking by reducing the background. This article introduces basics of neutron shielding, physics and suitable materials for neutron and gamma-ray shielding, and an example of conceptual shielding design for the 1-MW spallation neutron source of J-PARC MLF.
