A radiation shielding arrangement for shielding high-energy neutron radiation
and
gamma radiation from high-energy particle accelerators or storage rings includes
a shielding element made of water-containing material, for example with chemically
bound water or water of crystallization, in particular gypsum. The water component
of the material preferably makes up at least 5, 10 or 20 percent by weight. The
hydrogen nuclei or protons contained therein moderate neutrons in a virtually ideal
manner because of the almost identical mass and the maximum pulse transformation
associated with this.
