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).

Estimation of radon exhalation rate from a brick wall during various stages of construction by measuring exhalation rates from various building materials

open access: yesRadiation Protection and Environment, 2020
Radon concentration in a room can be predicted from accurate knowledge of exhalation rates from six surfaces of the room. Walls of a room occupy the maximum surface area of the room.

Measurement of Radon Exhalation Rate from Pottery Meal Dishes in Erbil City by using Passive and Active Techniques [PDF]

open access: yesKirkuk Journal of Science, 2012
Solid State Nuclear Track Detectors (SSNTDs) of type CR-39 has been used in this study as a passive method to measure the radon activity concentration, radon exhalation rate (in terms of area and mass), and effective radon content in the pottery meal ...

Radon and thoron exhalation rate, emanation factor and radioactivity risks of building materials of the Iberian Peninsula [PDF]

open access: yesPeerJ, 2020
Radon (222Rn) and thoron (220Rn) are radioactive gases emanating from geological materials. Inhalation of these gases is closely related to an increase in the probability of lung cancer if the levels are high.

Natural Fracture Ventilation Altering the Ground Thermal Regime in Unstable Rock Slopes—A Case Study From Western Norway

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 11, November 2026.
Abstract Open bedrock fractures are common features in unstable rock slopes and alter subsurface thermal conditions of fractured rock masses through convective air ventilation and atmospheric exchange. These processes are particularly relevant in cold mountain environments, where variations in ground temperature affect rock mass stability and may allow

RADON EXHALATION FROM GRANITIC ROCKS

open access: yesBrazilian Journal of Radiation Sciences, 2019
Naturally occurring radionuclides such as radon (222Rn), its decay products and other elements from the radioactive series of uranium (238U and 235U) and thorium (232Th) are an important source of human exposure to natural radioactivity. The worldwide evaluation of health radiobiological effects and risks from population exposure to natural ...

Greater Mouse‐Tailed Bats Glide During Approximately 50% of Their Flight

open access: yesAnnals of the New York Academy of Sciences, Volume 1564, Issue 1, October 2026.
ABSTRACT Flapping flight is widely regarded as a mechanically complex and energetically demanding mode of locomotion. In bats, the evolution of flapping flight is hypothesized to have arisen from gliding, an unpowered form of aerial movement. Although intermittent flap‐gliding flight is considered advantageous in many bird species, this flight strategy
