Effect on Radon Exhalation Rate Due to Cracks in Concrete
Nordic Concrete Research, 2019 The second largest cause of lung cancer in the World is related to radon (222Rn) and its progenies in our environment. Building materials, such as concrete, contribute to the production of radon gas through the natural decay of 238U from its constituents.
