From Radon and Thoron Measurements, Inhalation Dose Assessment to National Regulation and Radon Action Plan in Cameroon [PDF]
Journal of Radiation Protection and Research, 2022 Background The current study reports measurements of activity concentrations of radon (222Rn) and thoron (220Rn) in dwellings, followed by inhalation dose assessment of the public, and then by the development of regulation and the national radon action ...

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

Distribution of indoor thoron in dwellings under normal and turbulent flow conditions using CFD simulation technique [PDF]
Nuclear Technology and Radiation Protection, 2017 Extensive work has been carried out on measurement of radon and thoron levels in indoor environment in last three decades. These studies are important from radiation protection point of view, if one considered the contribution of radon, thoron ...

Comparative analysis of radon, thoron and thoron progeny concentration measurements [PDF]
Journal of Radiation Research, 2013 This study examined correlations between radon, thoron and thoron progeny concentrations based on surveys conducted in several different countries. For this purpose, passive detectors developed or modified by the National Institute of Radiological Sciences (NIRS) were used.
