“…(4). The change in absorbance-A at 300-305 nm was also happen when determine comparison between solar UV-simulator and overhead sun for CR-39 [14]. And this change in absorbance-A at 305 nm was happen as result of attributed to the formation of conjugated system of bonds due to bond cleavage and reconstruction supporting the structural and chemical modification in PC (Lexan) after irradiation [13].…”

In the present work, studies the effect UV-radiation dose(1 J/cm²-360 J/cm²) with power 15 W to Lexan track detector thickness175 µm. Absorbance-A was measured at wavelength 300 nm and 305 nm by using UV-visiblespectroscopy and measure the transmission percent-T% and deviation at the wave number-w 940cm-1 by using Fourier infrared-FTIR spectroscopy. The relationship between the radiation dose of the UV-radiation (J/cm²) and the absorbance-Aat wavelength 300 nm and 305 nm and the wave number-w 940 cm-1 was calculate as a polynomial relation .The present study show that there is a possibility to use the detector Lexan to assessment doses of exposure to UV-radiation in the medical and environmental fields .

“…It plays an important role in commercial applications involving both the radiation processing of polymeric materials and the use of polymers in certain optical devices in radiation environments (4). Numerous publications have dealt with the investigation of the color changes in irradiated polymers and the use of NTDs in radiation dosimetry (5)(6)(7)(8)(9)(10)(11)(12)(13)(14). Some of these publications have reported that, in some NTDs, noticeable changes in color are *Corresponding author.…”

Effects of electron beam irradiation on the color changes of the Bayfol CR 6-2 nuclear track detector have been investigated. Samples from CR 6-2 were irradiated with an electron beam at the dose range 50-400 kGy. The transmission of these samples in the wavelength range 400-800 nm, as well as any color changes, was studied. The Commission International de E'Claire (units x, y and z) methodology was used in this work for the description of colored samples. The color differences between the non-irradiated sample and those irradiated with different electron beam doses were calculated. The results indicate that the CR 6-2 detector acquires color changes under electron beam irradiation. This result is compared with those obtained from our previous work, for different polymers due to electron beam irradiation. In addition, as a review, our previous results on color changes in some irradiated polymers were collected and compared together.

This paper discusses the results of investigations of beta and gamma radiation induced thermoluminescence (TL) of CR-39 polymer. As the material is cheap and easily available, the feasibility of CR-39 being used for personal dosimetry is worth investigating. Samples from CR-39 of dimensions 3mm × 3mm were classified into two main groups. The first group was irradiated with gamma rays from 137 Cs source, while the second group was exposed to beta particles from 90 Sr source and read for TL emission on a TLD reader, Harshaw 4500. The chips were annealed at different temperatures to find out optimum annealing temperature to get rid of the background to a maximum. Different annealing times were also studied for optimization. The heating temperatures in the TL reader were studied in a wide range so as to assess the best possible heating temperature. The possible enhancement of TL response of CR-39 exposed to gamma rays in the presence of oxygen and carbon dioxide was also studied. Dose response of CR-39 exposed to gamma rays in the presence of oxygen is better than that in the presence of carbon dioxide. The response of the exposed polymer in the presence of carbon dioxide is found to be better than that in the presence of air.
