Radiation shielding fiber is provided to increase width of selection by adjusting the thickness of a neutron shielding layer in accordance with the intensity of radiation neutron energy. Radiation shielding fiber includes a first and a second radiation shielding layers(1) and a neutron shielding layer(2). A coating layer is formed on surfaces of the first and the second radiation shielding layers. The coating layer is made of polyurethane resin. The neutron shielding layer is formed through mixing/extruding/cooling of thermoplastic polyolefin with 10 to 50 weight % and remaining molten paraffin. The thermoplastic polyolefin contains UHMWPE(Ultra-High Molecular Weight Polyethylene) with 1 to 5 weight %. The neutron shielding layer is a sheet having minute air holes. |
