“…The gamma radiation dose response at wavenumber 2962 cm −1 was appear as a result of alkyl asymmetry C-H bond stretch out of skelated plane [14] after change in chemical structure of PM-355 by gamma or neutron radiation. But the gamma radiation response of wavenumber 1265 cm −1 was appear as a result to deformation of a weak absorption for C-Cbond for structure of PM-355.…”

“…In 2013 Emad Hassan Aly [12] obtained the microstructural investigation of PM-355 from the response of low dose gamma irradiationby by using a positron annihilation lifetime study. On other side, the studies which include both the effects of gamma and neutron radiation are taken into account [13] [14].…”

“…And calculating the linear relationship observed between the decrease in activation energy and the gamma-neutron dose being received by the detectors suggests the possibility of the use of these detectors as gamma and neutron dosimeters [15]. Abdel Raouf et al 2013 [14] studied the effects of irradiated gamma rays, X-rays and alpha particles on CR-39 by FTIR-spectroscopy, which show the optical density of the detector was calculated and then it was used to determine alpha range [14]. In this study, the relation between the radiation dose of gamma radiation and thermal neutron on PM-355 detector and some values of transmission percent which measured by FTIR-spectroscopy will be determined.…”

The effect of gamma on nuclear track detector type PM-355 (at the dose range 200 to 1600 kGy) and thermal neutron (flux 10 5 n•cm −2 •s −1) was calculated by using of two irradiation methods. First method (G + N) was an irradiation PM-355 detector by gamma radiation and then irradiation by thermal neutrons, and another method (N + G) was irradiated by thermal neutrons and then gamma radiation. FTIR-spectroscopy was used to measure the change in deferent of transmission percent ΔT% at the wavenumber 1260 cm −1 with wavenumber 2962 cm −1 [ΔT%] 1260-2962 and wavenumber 1138 cm −1 [ΔT%] 1260-1138. The values of [ΔT%] 1260-2962 and [ΔT%] 1260-1138 were increasing with the increase of gamma irradiation with maximum response at 820 kGy and then drop after this dose until to 1600 kGy. This study determined the linear equations relation between the effect of gamma radiation on PM-355 detector and the change of [ΔT%] 1260-2962 and [ΔT%] 1260-1138, and this change appeared in (N + G) irradiation method better than in (G + N) irradiation method. The appearance of wavenumber 2964 cm −1 in (G + N) irradiation method referred to alkyl asymmetry C-H bond stretched out of skelated plane after changes in chemical structure of PM-355 detector by gamma or neutrons radiation.

The effect of gamma radiation on CR-39 detector was determinate through the image processing for the photoelasticity images by using of MATLAB software. The maximum change different in CR-39 detector colors at photoelasticity technique was appear at the value 2 kN as a mechanical compression effect. It was adopted this value of mechanical compression on CR-39 detector to calculation the change in color percentage -C% for four colors red, green, magenta and yellow. It was found the increase of gamma irradiation dose -D(Gy) on CR-39 detector at the range (100 to 600 Gy) lead to change in color percentage - C% for four colors. The polynomial equation for red color was a good smooth relation compared with polynomial equations for green, magenta, where the yellow color behavior as a logarithmic relation. The red color relation used to determination the effect of gamma radiation on CR-39 detector due to the clear behavior between D(Gy) with C%. In this study, we can consider that the image processing for the photoelasticity images of CR-39 detector by using of MATLAB software was a good method to calculate the effect of gamma radiation on CR-39 detector compared with other methods in this field.
