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.

Measurements of thoron exhalation rates from soil and building materials with scintillation cell

, 2004
In the past decades, international data base on radon (Rn-222) has been improved steadily. However, representative data on thoron (Rn-220) are still few.

Simulation of thoron and thoron progeny concentrations in the indoor environment

, 2011
Thoron (220Rn) exhalation from building materials has become increasingly recognized as a potential source for radiation exposure in domestic houses. However, contrary to radon (222Rn), little is known about the exposure to thoron and its short-lived ...

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).

Radon and thoron inhalation doses in dwellings with earthen architecture: Comparison of measurement methods.

, 2017
The radioactive noble gas radon (222Rn) and its decay products have been considered a health risk in the indoor environment for many years because of their contribution to the radiation dose of the lungs.
