Solid State Nuclear Track Detectors (SSNTDs) are well known for the detection of ionizing radiation through track formation of heavy ionizing particles. The LR-115 detector is a commonly used SSNTD for the detection and measurement of Rn and its progeny. Several techniques of track revelation are known but, the chemical etching technique is the most frequently used in which tracks can be made v...

We have determined the detection sensitivity of the LR 115 detector placed on the bottom of hemispherical diffusion chambers through Monte Carlo simulations. For the cases where the LR 115 detectors completely cover the bottom of hemispherical diffusion chambers, we propose the optimum radius of the hemispherical chamber as 3 cm. In hemispherical chambers with radii smaller than 3 cm, the total...

Equations for calculating track parameters have been proposed, which invariably involve the track etch rate Vt and the bulk etch rate Vb. The present study measured Vb for the LR115 solid-state nuclear track detector using atomic force microscopy (AFM). The detectors were partially masked using rubber cement and then etched in 2:5 N NaOH solution at 60◦C for time periods ranging from 5 to 40 mi...

Introduction: Radioactive material is always present in the environment, and the largest contribution to the inhalation exposure comes from the short half-life decay products of radon. Accordingly, the concentrations of radon were measured in the milk and tea samples collected from Misanmarkets in Iraq. Material and Methods: A total of 2...
