Investigation of proton and alpha radiation effects on polymer concrete by using GEANT4

In this study, the effects of proton and alpha radiation on polymer concrete material have been investigated by using GEANT4 which is a freely distributed code with a very wide range of use. The polymer's selection is due to its preferable regarding its physical and chemical properties such as low cost of production, ease of synthesizing and light weight etc. The radiation effects of different induced particles and also stopping power and penetrating distance investigations have been done to examine the possibility of using the polymer concrete as shielding material. To reach our aim as simulating the different situations, GEANT4's PhysListEmStandard and G4EmStandardPhysics libraries have been employed for two types of polymer concrete samples where one has 0 % natural standard CEN sand while other has 75 % of natural standard CEN sand. The rest of the studied materials consists of polyester resin. Obtained results such as the penetrating distance and the stopping power have been discussed for both studied materials. (authors)
