Abstract
Radiation-shielding transparent material comprising an aqueous solution of thallium formate with or without thallium malonate, the solution having a density of 2.5 to 4.3 g/cm.sup.3, a radiation length of 3.8 to 1.9 cm, and a transmission of not less than 93% for light of 400 nm wavelength. The material is produced by deoxidizing thallium formate and dissolving the deoxidized thallium formate in deoxidized distilled water.
