prepared The compound rubber material by reinforcing it with nanoparticle powder (N Pb) for protective shields in hospital X-ray units for the purpose of protecting fetuses from congenital deformity in pregnant women and workers in X-ray rays.
The addition of chlorophyll extracted from tree leaves and plants as a plasticizer and anti-oxidant with different ratios of (20 - 100 pphr) and (20 pphr) was chosen as a percentage that achieves the purpose, but prevented it from penetrating the X-ray radiation is very little even at high ratios, as well as TiO_2 of (20 - 100 pphr) was added. 20 as a micro-filler for the purpose of obtaining good mechanical properties such as tensile strength, elasticity and hardness with different ratios (20 -100 pphr). 20 pphr was chosen as a ratio that achieves the purpose, but it prevents it from penetrating the X-ray rays. Very few even at high ratios. And by adding nanoparticles lead (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 rays 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 (mm3) prevented the penetration of X-ray rays 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 rays and cut them at (110KV). In this way, the purpose of protecting the fetuses of pregnant women when they are exposed to radiation in the X-Ray units and their workers when using this material as a cover or shield with a thickness of (3 mm) was achieved.
