Shielding material and shielding element for shielding gamma and neutron radiation

摘要

Shielding Material and Shielding Element for Shielding Gamma and Neutron Radiation;A material for shielding radiation is disclosed, the material comprising:- a neutron moderator (13) based on a hydrocarbon,- a neutron absorber (12) based on B,- a gamma absorber (11) based on Fe,wherein the neutron absorber (12), the neutron moderator (13), and the gamma absorber (11) form a mixture, which comprises unbound particles and in which Fe, B and H have the following partial densities:- Fe: 2 to 5.5 g/cm³,- B: 30 to 150 mg/cm³,- H: 15 to 70 mg/cm³.;The total density of the shielding material ranges from 3.5 to 5.5 g/cm3. The shielding material remains in a particulate form and can be reused several times without reprocessing and does not pose a health hazard while delivering maximum shielding performance for sources that generate a combination of particle and gamma radiation.
