Abstract

In the present trackology work, CR-39 and CN-85, solid state nuclear track detectors (SSNTDs) were irradiated with alpha particles and gamma rays for different irradiation times. These detector foils were chemically etched by NaOH solution with specified normality. The intensity of transmitted laser light (λ=650nm) through irradiated and etched detectors was measured using a photodiode. The method appeared as a good technique for dose measuring but it is extremely dependent on the etching time, the type of incident particles and the type of the detector. It is found that the response of CN-85 detector looks faster and better than CR-39 detector.
