초록
At present, the most common substance used in radiation protection is lead. However,lead is a heavy metal that is harmful to the human body and causes environmental pollution. BaSO4 is an excellent material for X-Ray shielding because it has good X-Ray shielding abilityand it is cheap. In this study, we fabricated Gypsum-BaSO4 (G-B) shields with gypsum and BaSO4and Cement-BaSO4 (C-B) shields with cement and BaSO4 and conduct two tests (X-Ray shieldingtest, Strength test) to evaluate the performance of the shields. First of all, G-B, C-B Shields at 15mm thickness were fabricated to evaluate X-Ray shielding performance, including 1.0, 1.5 mmthickness lead and IKEN Board. To achieve X-Ray shielding capability of 1.5 mm lead at 100 kVX-Ray tube voltage, BaSO4 content 66% G-B shield and 68% C-B shield were required. Secondly,flexural strength test was conducted for G-B and C-B shields. Test results show that at the sameBaSO4 content, C-B shields were stronger than G-B shields. BaSO4 content 68% C-B shield was 3.5times stronger than 66% G-B shield.
