neutron beam shielding gypsum-based construction board, and method for producing neutron beam shielding gypsum-based construction board
The present invention provides a neutron beam shielding gypsum-based construction board which contains gypsum, a boron-containing material that contains from 1.0 part by mass to 120 parts by mass of boron relative to 100 parts by mass of the gypsum, and from 0.05 part by mass to 2.0 parts by mass of a water reducing agent relative to 100 parts by mass of the gypsum. The boron-containing material contains one or more substances that are selected from among calcium borate, boron carbide, boric acid, boron oxide, sodium borate and calcium boride; and the dry specific gravity thereof is from 0.65 to 1.6.
