In many countries, assessment programmes are carried out to identify areas where people
may be exposed to high radon levels. These programmes often involve detailed mapping …

Most of the natural radiation originates from radon, approximately 55%. This radiation occurs
because of the radioactive decay of natural uranium found in rocks, soil and water. Because …

A detailed geogenic radon potential (GRP) mapping based on field soil gas radon and soil
gas permeability measurements was carried out in this study. A conventional continuous …

A new theoretical framework for diurnal and seasonal oscillations of the concentration of
radon in soil and open air is proposed. The theory is based on the existing temperature …

Radon (222 Rn) is a radioactive gas that occurs naturally in the soil and is harmful to the
environment and health. However, the measuring the amount of radon flowing is …

This paper studies the temporal variation of soil gas radon activity concentration in a highly
permeable (k= 2.0 E-11 m 2) sandy-gravelly soil in order to understand if temporal variation …

We simultaneously measured radon and thoron exhalation rates in areas of weathered acid
rocks in Japan to investigate the relationship between them and between measured and …

The occurrence of radon (222 Rn) in environment (groundwater and indoor air) from
geogenic sources is receiving an growing attention due to its adverse impact on human …

Radon and its progeny have been recognized as one of the major contributors to the natural
radiation and health hazards in the human dwellings. Even lung cancer is expected if it is …

Radon concentration has been monitored from 1995 to 1999 in the soil of the Sur-Frêtes
ridge (French Alps), covered with snow from November to April. Measurements were …
