屏蔽箱室内窥视窗玻璃选材研究

Abstract

Abstract: Traditional endoscopic windows of shielding enclosures are often made of radiation resistant optical glass. However, this type of glass is brittle and the breakage risk of large glass is high. Therefore, it is necessary to select glass that is more suitable for large endoscopic windows from commonly used glass. This article focuses on PC galss, PMMA and K509. γ irradiation and neutron irradiation tests were conducted to compare the changes in color and transmittance of various materials. The tensile, bending, and impact resistance of glass before and after γ irradiation were analyzed. It was found that PC glass possessed high transparency, good toughness, and excellent impact resistance, which was a more suitable material for large endoscopic windows. This study could provide reference for similar shielding enclosure designs in the future.

Key words: PC glass, PMMA, K509, neutron irradiation
