Radon exhalation rate prediction and early warning model based on VMD-GRU and similar day analysis.
Journal of Environmental RadioactivityTo improve the safety and reliability of radon exhalation rate monitoring systems, this study introduces an early warning method that integrates a VMD-GRU prediction model with a similar day analysis.

In this paper the authors present a collection of radon emanation and exhalation rate data of about 2000 samples of building materials used in Europe. The data analysis highlighted some critical issues, such as the use of different units to express radon

Relation Between Limiting Exhalation Flow Rate and Lung Volume
IEEE Transactions on Biomedical Engineering, 1987A previous communication presented a procedure to convert perturbational airways resistance to plethysmographic resistance. While working with this procedure, we discovered that one of the unknown exhalation parameters must be, set to a value of 1.0, and another represents the inverse of the respiratory system time constant.

Radon and Thoron exhalation rate map in Japan
AIP Conference Proceedings, 2008Measurements of radon and thoron exhalation rates have been done using the radon and thoron exhalation rate measuring instrument adopting the accumulation method. We obtained the 111 data in the 40 sites of the 14 prefectures in Japan. The arithmetic average value of the radon and thoron exhalation rates by all 111 data were obtained to be 8.6 mBq⋅m−2 ...
