摘要： Provided is a neutron shielding material having good light transparency and excellent shielding performance against thermal neutron rays, and a method for producing the same. A neutron shielding material according to the present invention includes a light transmitting material and a boron compound enriched in a boron isotope having a mass number of 10, the neutron shielding material being formed of a molded product having light transparency. Shielding performance against thermal neutron rays is improved by containing a boron compound enriched in a boron isotope having a mass number of 10. As a result, the neutron shielding material can be widely applied to members requiring visibility and neutron blocking properties.
