Abstract:

As the use of radiation increased from last few decades, the need for the study of radiation effects on materials, a phantom etc is most important. We know nowadays the radioisotopes or radioactive substances used in many fields like in medical field, nuclear power plants, and radiation research etc. Many researchers did a lot of experiments in this field and found different conclusions.  In the present study we used the polymeric materials which can be available easily, having low cost, can be used at large scale. The results investigated and calculated were most useful in the fields of gamma radiation shielding, dosimetry, material science etc. Also radiation is widely used in biomaterial science for the surface modification, sterilization and to improve bulk properties of materials.

In the present work we investigated the gamma radiation parameters as mass attenuation coefficient, the total atomic scattering cross-sections, the electronic scattering cross-sections, the effective atomic numbers, and the effective electron densities for some polymers such as polyoxymethylene (CH2O), poly acrylonitrile (C3H3N), natural rubber (C5H8), poly ethyl acrylate (C5H8O2 ), polyphenyl methacrylate (C10H10O), and polyethylene tetraphthalate (C10H8O4 ). The gamma ray photons were detected by NaI(Tl) detector with resolution of 8.2 % at 662 keV, using radioactive gamma ray sources 57Co, 133Ba, 137Cs, 54Mn, 60Co, and 22Na at energies 122, 356, 511, 662, 840, 1170, 1275, and 1330 keV. Values of m/e for the chosen polymers decrease with increasing energy. The results of investigated data are useful in plastic industry, building materials, agriculture fields radiation shielding, accelerator centers, polymer industry, medical field, etc.
