Abstract
The effects of gamma and electron beam irradiation on the color changes of PM-355 nuclear track detector have been investigated. Samples from PM-355 were classified into two main groups. The first group was irradiated with gamma in the dose range of 10-250 kGy, while the second group was irradiated with an electron beam at the same dose range. The transmission of these samples in the wavelength range of 370-770 nm, as well as any color changes, was studied. The Commission International de E'Claire (CIE units x, y and z) methodology was used in this work for the description of colored samples. In addition, the color differences between the non-irradiated sample and those irradiated with different gamma or electron beam doses were calculated. The results indicate that PM-355 detector acquires color changes under gamma and electron beam irradiation, but it has a more response to color changes by electron beam than that by gamma.
