Radon is a member of the 238 U decay chain whereas thoron is a member of the 232 Th decay chain.Because radon and thoron are members of different decay chains, their concentrations depend in part on the uranium and thorium levels in local soils and building materials. WebAsked By : Julie Martin. Radon is a member of the 238U decay chain whereas thoron is a member of the 232Th decay chain. Because radon and thoron are members of different decay chains, their concentrations depend in part on the uranium and thorium levels in local soils and building materials.
WebA simplified version of the 232Th + 208Pb decay chain is shown in Fig. 1. The alpha decay of 224Ra (radium) leads to the formation of 220Rn (radon) with a half- ... gas was called thorium emanation, or thoron, but it is in fact an isotope of the element radon (220Rn). The decay of 238U also leads through a series of alpha and beta decays to a radon WebFeb 14, 2014 · In general, the short-lived radon decay products present the dominant radiation risk. Radon is a member of the decay chain of uranium which makes up about 3 ppm of the earth’s crust. Consequently, radon is not limited to mines; it occurs everywhere, outdoors in usually low concentrations and indoors in higher concentrations.
WebBased on the decay kinetics of serial nuclear transformations, the progeny weighting factors, with values between 0 and 1, are derived by analysis of the time-integrated activity of each nuclide in the (branched) decay chain headed by a parent nuclide. Using the electronic, nuclear-decay database of Publication 107 of the International ... Radon is a colorless, odorless, and tasteless gas and therefore is not detectable by human senses alone. At standard temperature and pressure, it forms a monatomic gas with a density of 9.73 kg/m , about 8 times the density of the Earth's atmosphere at sea level, 1.217 kg/m . It is one of the densest gases at room temperature and is the densest of the noble gases. Although colorless a…
WebRadon is a colourless, odourless, tasteless noble gas that comes from the disintegration of uranium contained in rocks forming part of the Earth’s crust. 6 Exposure to radon is ubiquitous, and although the gas is swiftly diluted in the atmosphere, it can nevertheless accumulate in large quantities in closed spaces such as dwellings and workplaces. 7,8 …
