Purpose Soil is the prime source of radon and thoron concentrations in the household
dwellings. The presence of radioactive gases in the environment is mainly due to the …

Studies on radon have become the focus of indoor radiation. In this study, we chose
greenhouse to be the study field, the research aims to:(1) explore the diurnal variation of …

Concentration of radon (222 Rn) in the near-ground atmosphere has been measured quasi-
continuously from January 2005 to December 2009 at two continental sites in Europe …

The radon (222Rn) in the outdoor atmosphere has been investigated in many studies. It was
found out that daily and seasonal variations of the 222Rn concentration occur near the …

Atmospheric concentrations of radon (222 Rn) gas and its short-lived progenies 218 Po, 214
Pb, and 214 Po were continuously monitored every four hours at the ground level in Jeddah …

Continuous measurements of the concentration of Radon (222 Rn) and its progenies were
made with a Radon detector, RTM 2200, at a tropical site, Pune (18° 31′ N, 73° 55′ E …

Radium-226 is a significant source of radon-222 which enters buildings through soil,
construction materials or water supply. When cigarette smoke is present, the radon …

Radon (222Rn) and thoron (220Rn) from soil gas are very significant factors that can affect
the indoor radon level in the first floor or in the basement. China is one of the countries with …

This thesis provides the measurements of 222Rn exhalation rates, 210Pb deposition rates
and excess 210Pb inventories for locations in and around Ranger Uranium Mine and Jabiru …

Two years of in situ radon concentration measurements in the atmospheric surface layer
have been collected in a central Italy town (L'Aquila), located in the Aterno river valley …
