Measurements of Indoor Radon Levels in India using Solid~State Nuclear Track Detectors: Need for Standardisation
Solid-state nuclear track detectors are being used to obtain the time integrated concentration levels of indoor radon/thoron and their daughters. This technique is preferred for taking such measurements in dwellings Such measurements are important as the radiation dose to human beings due to indoor radon constitutes more than 50 per cent of the total dose including that received from the natura...
متن کاملSolid State Nuclear Track Detectors and Their Applications
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...
متن کاملDigital System to Characterize Solid State Nuclear Track Detectors
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...
متن کاملResidential Radon Concentrations in Kathmandu Valley Using Solid State Nuclear Track Detectors
Measurement of radon is very important in dwellings because of its radiological impact on public health. Radon contributes more than half of the total ionizing radiation dose. It is known from the recent surveys in many countries that radon is the second cause of lungs cancer after smoking. In this context, we have measured radon ( 222 Rn) concentration in different dwellings of Kathmandu valle...
متن کاملLong-term determination of airborne radon progeny concentrations using LR 115 solid-state nuclear track detectors
This paper described the establishment of lognormal distributions for the Jacobi room model parameters with a view to improve an existing method for long-term passive measurements of the equilibrium factor using LR 115 solid-state nuclear track detectors, namely, through the proxy equilibrium factor (Fp) method. Fp is defined as (C1 þ C3)/C0 where C0, C1 and C3 are the concentrations of 222Rn, ...
