background: in this study, measurement of indoor radon and its progeny levels was carried out in gas turbine power station in haryana ( india ), where natural gas is used as fuel. for comparison, the results of a study carried out in thermal power plant in haryana are also presented. radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

It is an established fact that radon progeny can induce lung cancers. However, there is a well-known discrepancy between the epidemiologically derived dose conversion factor for radon progeny (4 mSv/WLM) and the dosimetrically derived value (15 mSv/WLM) (mSv is a unit of the dose while WLM is a unit of exposure to radon progeny). Up to now there is no satisfactory explanation to this. In the pr...

This paper presents the exact method for radon equilibrium determination by gamma spectrometry measuring of radon progeny concentrations in the air. The method is based on simultaneous sampling of air through the filter paper and alpha spectrometry measurement of radon activity concentration in the air. This paper derived a mathematical formula to calculate the initial concentrations of radon p...

The present paper deals with the study of the multiple linear regression model for the estimation and prediction of the time series of radon and thoron progeny concentrations in atmosphere. The general purpose of multiple linear regression model is to find the linear relationship between a dependent (or explained) variable and several independent (or predictor) variables. Radon and thoron proge...

Eyeglass lenses are commonly composed of allyl-diglycol carbonate (CR-39), an alpha-particle detecting plastic, thus making such lenses personal radon dosimeters. Samples of such lenses have been etched to reveal that radon and radon progeny alpha tracks can be seen in abundance, and sensitivities have been calibrated in radon chambers as a primary calibration and with a uranium-based source of...

Abstract 222 Rn emanating from environmental dust constitutes an important background component for many low-energy, low-rate experiments. Radon emanation rates and rock, thus, are experiment planning. In this paper, we report measured radon fractions five types of dry differing in grain size composition. These data were obtained by a novel technique γ -spectroscopy, measuring emanated non-eman...

Although radon dose to lungs comes mainly from shortlived radon daughters, most of its estimations for general population is based on the measurements of radon gas concentration instead of radon progeny and acceptance of a constant equilibrium factor between radon and its short-lived decay products. It is so because integrating passive measurements of radon gas concentration are simpler and che...

A simple method employing a pair of pancake-style Geiger-Mueller (GM) counters for quantitative measurement of radon activity concentration (activity per unit volume) is described and demonstrated. The use of two GM counters, together with the basic theory derived in this paper, permit the detection of alpha particles from decay of 222 Rn and progeny ( 218 Po , 214 Po ) and the conversion of th...

A modern human receives most of the radioactive annual dose in buildings from radon and its progeny, which can cause lung cancer. In such conditions, design radon-safe is an urgent task context preserving population collective health. The paper shows inefficiency using flux density soil surface as a criterion for potential hazard construction site due to significant temporal spatial variability...
