Manufacture Shield from nano-rubber composite to protection from X-ray radiation

Abstract

The rubber was reinforced with nanoparticle powder (N Pb) to prepare shields in hospital X-ray units for the purpose of protecting women and workers in X-rays. The addition of chlorophyll extracted from tree leaves and plants as a plasticizer and anti-oxidant with different ratios of (20 – 100) pphr . (20 pphr) was chosen as a ratio that achieves the purpose, but prevented it from penetrating the X-ray radiation is very little even at a high ratio, as well as TiO2 was added with different ratio (20 – 100) pphr. 20 pphr was chosen as a ratio that achieves the purpose and obtaining good mechanical properties such as tensile strength, elasticity and hardness, but it prevents it from penetrating the X-ray was very few even at high ratios. Then adding nanoparticles lead(N Pb) with different ratio (40 – 350) pphr. Good results in cutting the radiation penetrate the X-ray and the best ratios (100, 200, 300, 350) pphr. As adding (100 pphr) of N Pb to the rubber with a thickness (2 mm) the X- ray were penetrated and cut at (60 KV). Whereas, adding (200 pphr) of N Pb to the rubber with a thickness of (2 mm) prevented the penetration of X-Ray rays and cut them at (80 KV). Whereas, adding (300 pphr) of N Pb to the rubber with a thickness of (3 mm) prevented the penetration of X-ray and cut them at (100KV). Whereas, adding (350 pphr) of N Pb to the rubber with a thickness of (3 mm) prevented the penetration of X-ray and cut them at (110KV). In this way, the purpose of protecting women and their workers from X-ray radiation when using a shield with a thickness of (3 mm) was achieved.
