Optimization of chemical etching parameters of strippable and non-strippable solid state nuclear track detectors (SSNTD) LR 115 type II

In this study, optimal experimental parameters, especially the optimum time and the residual thickness for the revelation of latent tracks left behind by alpha particles emitted by radon gas and its progeny on strippable and non-strippable Solid State Nuclear Track Detectors (SSNTD) LR 115 type II have been first determined. Then, the track density of the strippable films has been normalized. For a residual thickness of 6 µm, the values of the optimum time and the normalization coefficient of track density obtained are respectively 120 minutes and 0.26 ± 0.03. These values are in close agreement with those reported by different authors. The results of this study allowed us to select the optimal conditions for the chemical etching of the SSNTD used for radon gas monitoring in Côte d’Ivoire.
