    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/cm 3 ,
    - B: 30 to 150 mg/cm 3 ,
    - H: 15 to 70 mg/cm 3 .
    The total density of the shielding material ranges from 3.5 to 5.5 g/cm 3 . 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.
