Modeling of radon exhalation from soil influenced by environmental parameters

Science of the Total Environment, 2019
Atmospheric radioactive noble gas radon (Rn-222) originates from soil gas exhaled in the atmospheric surface layer. Radon exhalation rates from soil as well as corresponding meteorological and soil parameters were recorded for two subsequent years. Based

Unraveling the complex interplay between soil characteristics and radon surface exhalation rates through machine learning models and multivariate analysis.

Environmental Pollution, 2023
This research seeks to elucidate the intricate interplay between soil characteristics and the rates of radon surface exhalation rate. To achieve this aim, Light Gradient Boosting Machine (LightGBM) and eXtreme Gradient Boosting (XGBoost) machine learning

Soil and air radon/thoron exhalation rates and radon activity concentrations in the vicinity of Lake Monoun, West region of Cameroon

International Journal of Environmental Analytical Chemistry, 2023
One crucial element to determine the radon amount in the environment is the rate at which radon is exhaled from the subsurface. To assess the radon and thoron potential exhalation in the vicinity of Monoun Lake in the West Region of Cameroon, 28 soil ...

Study on the characteristics of radon exhalation from rocks in coal fire area based on the evolution of pore structure.

Science of the Total Environment, 2022
Radon is of great significance as a tracer for the detection of coal fires due to its distinct variations in radon exhalation properties while heating. The research on radon exhalation performance through pore structure is still in its early stages.
