A digital system to characterize solid state nuclear track detectors(SSNTD) has been developed. It was used in the study of two detectors and its performance evaluated by comparing the obtained results with those determined by using an analog system, already in use for such purpose. The comparison of the results together with the feasibility and rapidness in data acquisition have demonstrated t...

Measurements using the LR 115 solid-state nuclear track detector (SSNTD) depend critically on the removed thickness of the active layer during etching, which cannot be controlled by the etching period alone. For example, the bulk etch rate depends significantly on the strength of stirring during etching. We propose here a fast, inexpensive and nondestructive method based on a color commercial d...

Among numerous applications of Solid-State Nuclear Track Detector (SSNTD), one important application is estimating radon and thoron concentration in an indoor environment. The primarily used SSNTD for this LR-115. Studying the behaviour these SSNTDs different etching solutions essential. In report, Lithium hydroxide solution was to etch LR-115 SSNTD. study thickness film removed carried out at ...

Solid-state nuclear track detectors (SSNTDs) have been widely applied for measurements of environmental concentrations of 222Rn and its progeny. The V function for an SSNTD is important for understanding the track development in the SSNTD as well as for real life applications. The partial sensitivity rhoi of the LR 115 detector applied in the bare mode to 222Rn and its short-lived progeny is re...

The feasibility of using the active layer of the colorless LR 115 SSNTD for alpha-particle radiobiological experiments was studied. The track revelation time on the bottom side (the side attached to the polyester base) was much longer than that on the top side (the side not attached to the polyester base) of the active layer so track formation on the top side was more desirable. In relation to ...

Energy-dispersive X-ray fluorescence (EDXRF) spectrometry was previously proposed to measure the thickness of the cellulose nitrate layer of he commonly used LR 115 solid-state nuclear track detector (SSNTD). The present work is devoted to the investigation whether the X-ray radiation nvolved in EDXRF spectrometry will induce degradation of the cellulose nitrate. For this purpose, Fourier trans...

In view of the fact that the radon progeny contribute the highest to the natural radiation dose to general populations, large scale and long-term measurements of radon and its progeny in the houses have been receiving considerable attention. Solid State Nuclear Track Detector (SSNTD) based systems, being the best suited for large scale passive monitoring, have been widely used for the radon gas...

The colorless LR 115 solid-state nuclear track detector (SSNTD) (from DOSIRAD) is based on cellulose nitrate and was first studied in view of its applicability in radiobiological experiments with alpha particles. In this paper, the bulk etch characteristics were studied. We first showed that the shape of the alpha-particle tracks are irregular with blurred contours under the optical microscope....
