Correction of the radon exhalation rate using the Kalman filtering to reduce measurement errors

Nuclear Engineering and Technology
The RAD7 detector is widely used for measuring the radon exhalation rate from the surfaces of media such as soil, rocks, and building materials. However, during the measurement process, the accuracy of the results is prone to interference due to the ...

Measurement of Radon Concentration Using SSNTD in Bartella Region

Al-Mustansiriyah Journal of Science, 2019
The alpha-radioactive inert gas Radon exhalation is associated with presence of Radium and its ultimate precursor uranium in the earth crust. Uranium decay deposits radon in soil, which is harmful on human and environment.

Artificial Neural Network Optimization to Estimate Radon in Soil

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 18, Issue 5, October 2025.
ABSTRACT Modeling and estimating radon concentration are of crucial interest to support health protection campaigns. In the literature, many studies concentrated on indoor radon, while few of them investigated the outdoor radon spatial distribution and the factors that influence its formation.

The closed-can exhalation method for measuring radon

Journal of Research of the National Institute of Standards and Technology, 1990
Results from closed-can radon exhalation experiments must be interpreted bearing the time-dependent radon diffusion theory in mind. A rapid change from the free to final steady-state exhalation rate will take place for all samples that are thin compared with the radon diffusion length.
