RISK: Lung cancer is the main health effect associated with radon exposure in humans. Radon-222: With daughters removed-1E+4: 4E-6: 1E-8--With daughters present-1E+2 (or 4 working level months) 3E-8 (or 0.33 working level) 1E-10--Page Last Reviewed Radon (Rn-222) is an odorless and colorless natural radioactive gas. It is produced during the radioactive decay of radium-226, itself a decay product of uranium-238 found in many types of crustal materials, that is, rocks and soils. Radon-222 decay products have been classified by the International Agency for Research on Cancer as being carcinogenic to humans, and as a gas that can be inhaled, lung cancer is a particular concern for people exposed to elevated levels of radon for sustained periods.

Uranium Paper V. Spatial correlation between radon (222Rn) in groundwater and bedrock method can be obtained, at 95% confidence level, using the formula (Currie. Consider the equation for the decay of radium-226 to radon-222, with the simultaneous loss of an alpha particle and energy in the form of a gamma ray. Use this idea to find the value of k for each element and then to write their equations.

2019-03-01 Radon-222 (222Rn, Rn-222, historically radium emanation or radon) is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial 2012-06-04 Radon-222 is one of the elements in the long radioactive decay chain from uranium-238, and the less common isotope radon-220 is part of the decay series from thorium-232. The elements above radon in the chain are relatively long-lived and of less concern for radiation exposure, but radon and the elements immediately following it in the chain are short-lived and therefore more hazardous. Radon-222 atom is a radon atom.
