Assessment of Radionuclide Concentration and Exhalation Rates in some NORMs and TENORMs of Shivalik Region

, 2023
520-525226Ra, 232Th, their decay products 222Rn, 220Rn and 40K significantly contribute to the mean dose from natural background radiation. This study reports the concentration of radionuclides in Naturally Occurring Radioactive Materials (NORMS) and ...

In situ Measurements of Radon and Thoron Exhalation Rates and Their Geological Interpretation

Japanese Journal of Health Physics, 2004
Radon and thoron exhalation rates from the ground were measured at 23 sites in Tokyo and nine prefectures of Japan that were selected in consideration of geological features and soil distribution. The in situ measurements were carried out with a ZnS (Ag) scintillation detector equipped with a photomultiplier and a container measuring 30×40cm and 11cm ...

Radon exhalation rate of some building materials common in Serbia [PDF]

, 2018
It is well-known that radon is the second important human carcinogen for lung cancer, after smoking. The major sources of indoor radon concentrations are soil and building material.

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.

Comparison of one- and two-filter detectors for atmospheric 222Rn measurements under various meteorological conditions [PDF]

, 2010
Parallel monitoring of 222Rn and its short-lived progeny (218Po and 214Pb) were carried out from November 2007 to April 2008 close to the top of the Schauinsland mountain, partly covered with forest, in South-West Germany.

Influence of thoron on measurement results of radon exhalation rate

, 2002
Because of thoron exhalation, the measurement results of radon exhalation rate using a local still method is usually larger than the true value of radon flux rate of the monitored material surface.

Thoron exhalation from building material and related indoor concentrations.

, 2008
Increased concentrations of thoron (220Rn) were recently measured in residential traditional dwellings in China (Tschiersch and Müsch, 2005, Shang et al., 2005) and India (Sreenath Reddy et al., 2004).
