GRAMLOCK X-ray shielding board is a rigid panel that can effectively block X-ray radiation without using lead (Lead Free). It is manufactured from gypsum (dihydrate gypsum, CaSO₄·2H₂O) and nonwoven glass fiber fabric. It has strength, fire insulation, and contains barium sulfate (BaSO₄) which provides X-ray shielding properties that are safe for living organisms and the environment (a green building material).
