The Effect of Grain Size on Radon Exhalation Rate in Natural-dust and Stone-dust Samples [PDF]

, 2015
Radiation dose to human population due to inhalation of radon and its progeny contributes more than 50% of the total dose from the natural sources which is the second leading cause of lung cancer after smoking. In the present work the dependence of radon

Measurement of the radon and thoron exhalation rates from the water surface of Yixin lake

Nuclear Engineering and Technology
The importance of determining the radon exhalation rate from water surface is emphasized by the increased use of radon and its daughter products as tracers in large-scale circulation studies of the atmosphere.

Radon exhalation rate in south-east Sicily building materials [PDF]

, 2015
One of the main contributions to indoor radon levels is given by the exhalation from building materials. For this reason we performed measurements of radon exhalation rate in materials commonly used in buildings of the eastern Sicily.

Return to an extreme environment exposure after pulmonary infection: SCUBA diving as a model?

Physiological Reports, Volume 14, Issue 7, April 2026.
Graphical overview of the experimental protocol used to investigate post‐COVID physiological responses during scuba diving at three different depths. Abstract The human body implements several adaptive mechanisms to perform in extreme environments. Increasingly, individuals return to such conditions after pulmonary infections, raising concerns about ...

QUANTIFICATION OF BACK DIFFUSION IN RADON AND THORON EXHALATION RATE MEASUREMENTS

Radiation Protection Dosimetry, 2020
Abstract The radon (222Rn) and thoron (220Rn) fluxes from the soil and building materials are the major contributors to their indoor levels. Hence, the measurement of radon and thoron exhalation rates from the source matrix becomes the foremost step in controlling the indoor radon and thoron exposure.

Measurement of Gas Fraction and Gas Permeability of Thawing Permafrost Caused by Climate Change

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Thawing of permafrost due to climate change is known to release gases such as the climate drivers carbon dioxide and methane, as well as the carcinogen radon. Gas permeability is extremely low in fully frozen permafrost and can be considered both to function as a seal preventing subsurface gases being released, and to prevent the creation of ...
