Lung cancer has high mortality and incidence rates. The leading causes of lung cancer are
smoking and radon exposure. Indeed, the World Health Organization (WHO) has …

Using data from a number of radon surveys, it was assessed that on average, radon progeny
concentrations in Canadian homes are about three times higher than in school buildings …

Exposure to indoor radon is identified as the main source of natural radiation exposure to
the population. Since radon in homes originates mainly from soil gas radon, it is of public …

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

Based on community and nationwide radon surveys with long-term radon measurements in

Radon has been identified as the second leading cause of lung cancer after tobacco
smoking. 222Rn (radon gas) and 220Rn (thoron gas) are the most common isotopes of …

Inhalation of radon (222 Rn) and its short-lived decay products and of products of the thoron
(220 Rn) series accounts for more than half of the effective dose from natural radiation …

Soil-gas 222 Rn concentrations were investigated on an active Simav Graben/Fault System
in Western Turkey. Measurements to understand the causes of variations in soil-gas 222 Rn …

Abstract From 2007 to 2013, simultaneous radon (222Rn) and thoron (220Rn)
measurements were conducted in a total of 3534 residential homes in 34 metropolitan areas …
