Abstract
In the present work we investigated the gamma radiation parameters as mass
attenuation coefficients ?/?, the total atomic scattering cross-sections ??,
the electronic scattering cross-sections se, the effective atomic numbers
Zeff, and the effective electron densities Neff for some polymers such as
polyoxymethylene (CH2O), poly acrylonitrile (C3H3N), natural rubber (C5H8),
poly ethyl acrylate (C5H8O2), polyphenyl methacrylate (C10H10O2), 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 ?/? 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.
