This paper reviews some aspects of solid-state nuclear track detectors (SSNTDs) and their applications in the radon and other research fields. Several geometrical models for the track growth given in the literature are described and compared. It is found that different models give close results for the dimensions of track openings.One of the main parameters that govern track formation is the bulk etch rate V b . Dependences of V b on different parameters such as the preparation procedures, etching conditions, irradiation before etching, etc. are examined. A review of existing methods for determination of the bulk etch rate and track etch rate V t is also given. Examples of V t functions for some detectors are presented. Some unsolved questions related to V t and some contradictory experimental results published in the literature are also summarized in the paper.Applications of SSNTDs for radon and progeny measurements are discussed. New designs of diffusion chambers that have appeared in the last few years are portrayed. A review of analytical and Monte Carlo methods for the calculation of the calibration factors in radon measurements is presented.Particular attention has been given to methods of long-term passive measurements of radon progeny with SSNTDs. These measurements are rather difficult and there is not yet a widely accepted solution. One possible solution based on the LR 115 SSNTD is outlined here.Methods for retrospective radon measurements are also described. Various applications of SSNTDs in other fields of physics and other sciences are briefly reviewed at the end of the paper. #

“…It is found that under electron irradiation PET and PI undergo both main chain scission and cross linking, but the presence of oxygen inhibits cross linking and the formation of oxygenated compounds increases. Yamauchi et al have performed a series of work in studying of bulk-etching behavior of a CR-39 detector irradiated with -rays (Yamauchi et al, 2001;Yamauchi et al, 2003). They noticed a signiÿcant enhancement in bulk-etching limited in the near-surface area.…”

“…The effect of gamma rays on the etching velocities in alkaline solution has been intensively investigated in order to understand the latent track formation in these detectors (Akber et al, 1980;Green et al, 1982;Zamani and Charalambous, 1985;Sharma et al, 1991;Shinha et al, 1997;Yamauchi et al, 1999Yamauchi et al, , 2001Yamauchi et al, , 2003a. In most of these works, the examined ranges of absorbed dose have been selected to be comparable to the local energy deposition in the centre of ion tracks.…”
