RADON EXHALATION FROM GRANITIC ROCKS
Brazilian 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 ...

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.
