It is important to measure the bulk-etching rate for any solid state nuclear track detectors, because they have an application in different fields of sciences. The effect of gamma rays emitted from 60 Co source with different doses on LR-115 detector was studied. The bulk etching rate of the detectors was measured before and after irradiation using gamma source. From the results the values of t...

The heavy ion interaction of 11.67 MeV/u 197Au+ 197Au has been investigated using mica as a passive detector. By employing Solid State Nuclear Track Detection Technique the data of elastic scattering as well as inelastic reaction channel was collected. The off-line data analysis of multi-pronged events was performed by measuring the three-dimensional geometrical coordinates of correlated tracks...

I am happy to announce today that the Department’s proposal to set up a Dr Homi Bhabha National Institute has been approved. This will bring together ten premier institutions all over the country under a single research-driven framework. This will help ensure that our scientists and our scientific establishments remain at the forefront of the pursuit of excellence, comparable with the best glob...

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...

In the traditional dwellings, source of Rn is the bare soil floor, either soil in cave dwellings or unburned adobe bricks and uncovered stone, wall in above ground dwellings. Because of the short half life of Rn, the indoor concentration is not homogeneous but increases towards the walls, floorings and ceilings. In view of this an extensive study is made by using the solid state nuclear track 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 ...
