Abstract
Disclosed is a radiation shielding zinc-barium-borosilicate glass material produced from easily accessible, low-cost and abundantly available starting raw materials, particularly for X-rays and/or gamma rays and/or fast neutrons and/or the like, having unique glass compositions. In particular, disclosed is the use of sodium oxide (Na2O), silicon dioxide (SiO2), boron oxide (B2O3), calcium oxide (CaO), barium oxide (BaO), zinc oxide (ZnO), bismuth oxide (Bi2O3), gadolinium oxide (Gd2O3) and cerium oxide (CeO2), which when mixed provides a satisfactory and effective shielding effect against X-rays and/or gamma rays and/or fast neutrons and/or the like.
Claims25
A radiation shielding zinc-barium-borosilicate glass which allows a transparent appearance to be provided in different areas where radiation-induced ionizing rays will occur, particularly in medical diagnostic centres and research institutes, and which can also be used to prevent harmful radiation from X-rays and/or gamma rays and/or fast neutrons and/or the like, wherein the glass comprises an addition of gadolinium oxide (Gd2O3) and/or bismuth oxide (Bi2O3) and/or cerium oxide (CeO2) to zinc-barium-borosilicate (ZnO—BaO—B2O3—SiO2) glass powder.
