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.
