Introduction: Natural radioactivity in the soil is considered a major indicator of radiological contamination. Primordial radionuclides are the main source of natural radioactivity. Natural radioactivity transfers radionuclides into the environment and poses radiation hazards to people's health. Therefore, the present study aimed to determine the radon concentration an...

In this study, the bulk etch rate (VB) was measured by three different methods forCR-39 with a thickness of 200µm and an area (1 × 1 cm2), where CR_39 irradiated through from Am241source energy alpha particles is 2.6MeV at angle fall perpendicular to surface CR-39 detector, detector etching (NaOH) concentration 6.25N (70 ± 1°C) showing effects formed on time periods ranging (0.25h) were photogr...

Presently, CR-39 Solid State Nuclear Track Detectors (SSNTD) is being used for Fast Neutron Personnel Monitoring in India. Individual detectors are cut manually from CR-39 sheets. Laser-cutting of the sheets will ensure precision and also save on the laborious efforts involved in sheet cutting. It was observed that there is a slight increase in background tracks due to laser-cutting. Studies we...

Computer programs have been developed to calculate track parameters and to plot track openings and wall pro$les. The programs are based on equations derived for three-dimensional consideration of track development. All possible cases of track openings and wall pro$les are obtainable from these equations. Results are given for lengths of major and minor axes, track depths and surface areas of tr...
