This paper describes importance of 220 Rn (hereafter thoron) progeny measurement for the
dose estimation. Although the spatial distribution of thoron activity concentration strongly …

Radon (222Rn) and thoron (220Rn), sources of natural background radiation, have been
the subjects of long-standing studies, including research into radon and thoron as major …

The annual exposure to indoor radon, thoron and their progeny imparts a major contribution
to inhalation doses received by the public. In this study, we report results of time integrated …

Radon, 222 Rn, is the major contributor to natural radiation in human environment. The
exposure of high radon is known as one of the causative factors of lung cancer. Though …

Exposure to radon, 222Rn, is assumed to be the most significant source of natural radiation
to human beings in most cases. It is thought that radon and its progeny are major factors that …

Although indoor radon was initially measured in the uranium regions of Poli and Lolodorf
using Electret Ionization Chambers, discriminative RADUET detectors were deployed in 70 …

The Chhatrapur placer deposit is found in a high background radiation area which has been
recently identified on the southeastern coast of India. Previously, some geochemical studies …

This study examined correlations between radon, thoron and thoron progeny concentrations
based on surveys conducted in several different countries. For this purpose, passive …

Indoor air and soil gas radon measurements are simultaneously performed in Hamirpur
district of Himachal Pradesh using RAD7, a solid state alpha detector. The study is …

Measurements of radon and thoron concentrations were taken at 70 locations in and around
Gandhinagar Gujarat, India. The radon concentration varied between 175 and 14,807 …
