The safety factor is the most important point to consider when using read more medical radiology, as the walls of X-ray rooms must be immune to the radiation at a safe level.The insulations that are currently used in large rooms in the radiation is a lead substance and because of this substance of toxic effects on the human was only touch or inhalation of its evaporation.So Our research is aimed at reducing the amount of lead used by increasing the susceptibility of the concrete wall to insulate the radiation by addition of two types of polymers Rheobuild 833 and Rheomac uw450 to the standard M15Mix IS-10262 concrete mixture for the construction of insulating walls using molds metals with dimensions (20,20,10) cm, and in quantities of ( 100, 200, 300) mg and evaluated to here determine their susceptibility to radiation capture.

The best isolating was found at the addition of 200 mg, with an improvement rate of 29% for the Rheobuild 833 polymer and 23% for the Rheomac uw450 polymer.
