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. #

“…Such a neutron dosimeter has the advantage that it is relatively insensitive to ~3, X and 3, radiation, and that a large range of doses can be studied on one recording film [119]. SSNDTs are also used in radon dosimetry [120].…”

The materials science aspects of the use of both polymeric and inorganic solids as detectors for energetic particles are reviewed. The various models proposed to explain the formation of an etchable track by a penetrating particle are discussed, as is the nature and the geometric consequences of the etching process itself. An account is given of the wide-ranging applications of solid state detectors in science and technology.

-Radon (222 Rn) is a radioactive gas that occurs naturally when uranium in soil and rock breaks down. Longterm exposure to 222 Rn increases the risk of lung cancer. The principal objective of this work was to determine the 222 Rn activity concentration in an indoor air environment at the El-Dabaa site proposed for a nuclear power plant project in Egypt using the track etch technique with LR115 detectors. The annual average indoor 222 Rn activity concentration in apartment buildings varies from 24 to 77 Bq.m −3 , with a mean value of 54 Bq.m −3 . The annual effective dose received by residents of the studied area was estimated to be 0.41 mSv. The annual estimated effective dose is less than the recommended action level by ICRP (3−10 mSv.y −1 ). The results from this work provide a radiological assessment program and update the background of the natural radioactivity map at the El-Dabaa site.
