Journal ArticleDOI
Long-term measurements of radon progeny concentrations with solid-state nuclear track detectors
TL;DR: In this article, the track parameters were first calculated using a track development model with a published V function, and by assuming a removed active layer of 6.54m, the relationship between the removed layer and the track diameter ofnormally incident 3 MeV -particles was then derived for the V function specifically determined for the LR 115 detectors used for the experiments.
Journal ArticleDOI
Measuring depths of sub-micron tracks in a CR-39 detector from replicas using Atomic Force Microscopy
TL;DR: In this paper, a method is proposed to prepare replicas of tracks from α particles in the CR-39 SSNTDs and to measure their heights using atomic force microscopy (AFM).
Journal ArticleDOI
Non-destructive measurement of active-layer thickness of LR 115 SSNTD
TL;DR: In this article, an exponential decay relationship between the infrared transmittance at the wave number at 1598 cm −1 and the thickness of the active layer for LR 115 detector was found.
Journal ArticleDOI
Application of the ray tracing method in studying α tracks in SSNTDs
TL;DR: In this article, the ray tracing method was applied to study etched tracks from α-particles in CR-39 solid-state nuclear track detectors, where the brightness of all elements was calculated systematically through the entire track to create the final image.
Journal ArticleDOI
Surface effect of ultraviolet radiation on electrochemically etched alpha-particle tracks in PADC
TL;DR: In this paper, the size of alpha-particle tracks on electrochemically etched ultraviolet-irradiated polyally-ldiglycol carbonate (PADC) films were studied and the mean sizes of the tracks were measured and were found to increase for short UV exposures and decrease for prolonged UV exposures.
