EFFECT OF PBO PERCENT ON TRANSMISSION PROPERTIES FOR (X-RAY) OF RUBBER COMPOUND (SBR)
Journal Title: Academic Research International - Year 2012, Vol 3, Issue 3
Abstract
The best way to Protect from Radiation in keeping the " ALARA " principle , where always trying to reduce the amount of potential radiation exposure to " As Low As Reasonably Achievable " , To protect from Radiation are by applying the flowing three principle of radiation protection one of them is Shielding .There for in this research preparation composite materials to protect Radiation, 5 different rubber compound were prepared by using (SBR 1502) type of Styrene Butadiene rubber in level and each recipe reinforced with Lead Dioxide (PbO) at different ratio (20,40,60,80 and 100) pphr ( part per hundred )and using Chlorophyll material as Reinforcement at constant value (100 % pphr), Titanium Dioxide (TiO2 ) at constant ratio (60) pphr at all compound. All of compound measure the transmission of (X-Ray).
