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

open access: yesNuclear 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 ...

Comparison Of Different Exhalation Filters In Protection Against Fugitive Aerosol During Nebulizer Treatments: An In-vitro Study [PDF]

open access: yes, 2021
Background: Aerosol escaping to the environment during nebulization treatments is called fugitive aerosol. Placing a filter at the exhalation outlet is one way to prevent unintended inhalation of fugitive aerosol by healthcare providers.

Estimation of global radon exhalation rate distribution [PDF]

open access: yes, 2008
A radon exhalation rate distribution model was developed, which considers dependency on soil water saturation, soil temperature and soil texture. The global averages of the radon exhalation rates were calculated to be 17.5 and 18.0 mBq·m^{-2}·s^{-1} by ...

EXPERIMENTAL TECHNIQUE TO MEASURE THORON GENERATION RATE OF BUILDING MATERIAL SAMPLES USING RAD7 DETECTOR [PDF]

open access: yes, 2013
Thoron (220Rn) is the second most abundant radon isotope in our living environment. In some dwellings it is present in significant amount which calls for its identification and remediation. Indoor thoron originates mainly from building materials. In this

Estimation of natural radionuclide and exhalation rates of environmental radioactive pollutants from the soil of northern India

open access: yesNuclear Engineering and Technology, 2020
The estimation of radioactivity level is vital for population health risk assessment and geological point of view and can be evaluated as rate of exhalation and source concentration (226Ra, 232Th and 40K).
