Correlations of nighttime atmospheric methane (CH 4) and 222 radon (222 Rn) observations
in Heidelberg, Germany, were evaluated with the radon tracer method (RTM) to estimate the …

The Anninghe fault (ANHF) and the Zemuhe fault (ZMHF) with left-lateral strike-slip, located
along the eastern boundary of the Sichuan-Yunnan block (southwestern of China), are some …

222 Rn is commonly used as a natural tracer for validating climate models. To improve such
models a better source term for 222 Rn than currently used is necessary. The aim of this …

This study demonstrates how the radon-222 (222 Rn) concentration of soil gas at an active
fault is sensitive to cumulative recent seismicity by examining seven active faults in western …

The spatial variation of soil gas radon values were correlated with the seismogenic faults
and earthquakes in the Tangshan area (north China). Radon concentrations were measured …

For on-site inspections (OSI) under the Comprehensive Nuclear-Test-Ban Treaty (CTBT)
measurement of the noble gas 37Ar is considered an important technique. 37Ar is produced …

Investigating the emissions of soil gas including radon, mercury and carbon dioxide (222Rn,
Hg and CO2) from the solid earth to the atmosphere through active fault zones is of great …

Naturally occurring radioactive noble gas, radon (222 Rn) is a valuable tracer to study
atmospheric processes and to validate global chemical transport models. However, the use …

Although greenhouse gas emissions during winter contribute significantly to annual
balances, their quantification is still highly uncertain in snow-covered ecosystems. Here …

Searching for small periodic signals, such as the 12 hr (S2) barometric tide, and monitoring
their amplitude as a function of time, can provide important clues on the complex processes …
