Radon is a colorless, odorless, and tasteless [15] 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 3, about 8 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3. [16]

In this latter table, where a decay has been predicted theoretically but never observed experimentally (either directly or through finding an excess of the daughter), the theoretical decay mode is given in parentheses and have "> number" in the half-life column to show the lower limit for the half-life based on experimental observation. Such ...
Alternatively, radon may enter the body through contaminated drinking water or through the decay of ingested radium [3] – making radon diffusion one of the greatest dangers of radium. [10] Thus, 222 Rn is a carcinogen ; in fact, it is the second leading cause of lung cancer in the United States after cigarette smoking , [ 3 ] with over 20,000 ...
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
Lung cancer is the only observed consequence of high concentration radon exposures; both human and animal studies indicate that the lung and respiratory system are the primary targets of radon daughter-induced toxicity. [1] Radon has a short half-life (3.8 days) and decays into other solid particulate radium-series radioactive
Radon in air forms a part of the background radiation, which can be observed in a cloud chamber. Most of the dose is due to the decay of the polonium (218 Po) and lead (214 Pb) daughters of 222 Rn. By controlling exposure to the daughters the radioactive dose to the skin and lungs can be reduced by at least 90%. This can be done by wearing a ...
