1 sty 1984 · Major areas of environmental research include the identification of geological factors associated with high radon levels, the behavior of radon daughters in various aerosol distributions, and the effects of certain architectural factors on radon daughter equilibrium status.
In 1989, a survey of the collective dose received due to radon in geothermal fluids was measured at 2 man-sieverts per gigawatt-year of electricity produced, in comparison to the 2.5 man-sieverts per gigawatt-year produced from 14 C emissions in nuclear power plants.
14 mar 2024 · Introduction. In the three primordial radioactive chains, three radon isotopes are created by α-transformation of radium [1]: 222 Rn (half-life, t1/2 = 3.82 days) in the uranium chain starting with 238 U, 220 Rn (t1/2 = 55.6 s) in the thorium chain starting with 232 Th, and 219 Rn (t1/2 = 3.9 s) in the actinium chain starting with 235 U (Figure 1).
3 dni temu · Humans receive around 50% of natural radiation dose due to 222 Rn (radon), 220 Rn (thoron) and their decay products. Several field campaigns measuring these gases and the decay products in ...
24 cze 2023 · The decay of uranium and thorium produces radon, a radioactive gas. Its concentration in the environment fluctuates based on local geology, soil permeability, climate, and terrain, as well as regional, seasonal, and daily meteorological conditions.
26 cze 2024 · Compounds: Though rare, radon can form compounds with highly electronegative elements, such as fluorine. Examples include radon difluoride (RnF2). These compounds are generally unstable and of significant interest in research. Isotopes: Radon has several isotopes, with Radon-222 being the most stable and common.
27 wrz 2024 · Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. It is a colorless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen. Learn more about radon in this article.
