Study on influence of soil and atmospheric parameters on radon/thoron exhalation rate in the Bangalore University campus, Bengaluru [PDF]

Radiation Protection and Environment, 2018
In the present study, Radon (222Rn) and Thoron (220Rn) concentration have been measured in the Bangalore University Campus using RAD7 during the postmonsoon season. The results reveal that 222Rn concentration ranged from 360 ± 146 to 643 ± 196 Bq/m3 with

Inhalation Dose and Source Term Studies in a Tribal Area of Wayanad, Kerala, India. [PDF]

J Environ Public Health, 2017
Among radiation exposure pathways to human beings, inhalation dose is the most prominent one. Radon, thoron, and their progeny contribute more than 50 per cent to the annual effective dose due to natural radioactivity. South west coast of India is classified as a High Natural Background Radioactivity Area and large scale data on natural radioactivity ...

Seasonal Variations in Radon and Thoron Exhalation Rates from Solid Concrete Interior Walls Observed Using In Situ Measurements

Atmosphere
Building materials, such as brick and concrete, are known indoor radon (222Rn) and thoron (220Rn) sources. Most radon and thoron exhalation studies are based on the laboratory testing of pieces and blocks of such materials.

The Radon Exhalation Rate and Dose Assessment of Granite Used as a Building Material in Serbia

Atmosphere
The application of energy-saving policies in buildings could lead to a decrease in the air exchange rate in dwellings, which could consequently lead to an increase in indoor radon concentration and, therefore, to an increase in resident exposure to ...

A Study of Natural Radioactivity Levels and Radon/Thoron Release Potential of Bedrock and Soil in Southeastern Ireland. [PDF]

Int J Environ Res Public Health, 2021
Radon (222Rn) and thoron (220Rn) account for almost two-thirds of the annual average radiation dose received by the Irish population. A detailed study of natural radioactivity levels and radon and thoron exhalation rates was carried out in a ...

Foraminifera assemblages from Fantangisña serpentinite mud seamount in the NW Pacific Ocean during the Pleistocene (IODP Expedition 366)

Journal of Quaternary Science, Volume 38, Issue 7, Page 1103-1127, October 2023., 2023
ABSTRACT The Mariana forearc system, in the northwestern Pacific, is known as the only convergent margin setting with currently active serpentine mud volcanism. The Fantangisña serpentinite mud volcano lies 62 km west of the Mariana trench, within the influence of the North Equatorial Current (NEC).
