Abstract |
|
|
| The linear attenuation coefficients (μL), and half value layer (HVL) thickness for high density polyethylene (HDPE) polymer with thickness 1 and 2 mm have been experimentally investigated at different energies of gamma-rays. In addition, theoretical calculations of μL and HVL have been done using In Situ Object Calibration Software (ISOCS). Three different gamma-ray energies were used; 661.7 keV from 137Cs, 1173 and 1332 keV from 60Co for both the experimental and theoretical methods. The measurements were carried out using falcon 5000 which is a portable electrically-cooled high pure germanium (HPGe) detector and g-spectrometer which provides radiation monitoring and nuclide identification and quantification. It is found that both experimentally and theoretically methods give nearly same results. Therefore, this task can be performed by any available method. In many situations, ISOCS calculations are preferred because of its cost in which includes money, effort, and time is lower than the experimental method. Also, it is found that ISOCS calculations are a very good method for the calculation of the linear attenuation coefficient and half value layer of the shielding materials at different photon energies. |
