24 cze 2023 · This review study examines the relationship between radon and geology, including its origins, transmission, and accumulation, as well as its impact on human health and mitigation strategies. The decay of uranium and thorium produces radon, a radioactive gas.
From the highest mountains to the deepest wells, radon’s presence is as widespread as the uranium from which it originates. Understanding where radon comes from is the first step in comprehending its potential impact on indoor air quality and, consequently, on our health.
Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only 222 Rn has a sufficiently long half-life (3.825 days) for it to be released from the soil and rock where it is generated.
18 sie 2023 · Radon is a radioactive gas that has no colour, smell or taste. It is produced in the ground from uranium and diffuses into the atmosphere. High concentrations of radon may build up in enclosed spaces such as buildings and long-term exposure can increase the risk of lung cancer.
5 lip 2013 · A final analysis of 243 tumors determined a TP53 mutation rate of 23.9%, whereby a higher percentage of individuals with TP53 mutations were observed in the high residential radon exposure group (42.9%) compared to the lower exposure group (20.9%), particularly among non-smokers.
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.
Radon (Rn) is an inert noble gas that does not interact chemically with other elements. All of the isotopes of radon are radioactive and evaluation of the adverse health effects due to exposure to radon requires additional consideration of the effects of radiation.
