WebThe gas thoron, or thorium emanation, is an isotope of radon ( 86 Rn 220) which decays by α emission and has a half life of 55.6 seconds. 2 Using an emanation electroscope, we observe the radioactive decay of thoron (separated from all its parent substances) by the progressive decrease of ionization in the air around the thoron.

Facts About Radon Live Science
Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colourless, odourless, tasteless noble gas. It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into various short-lived … See more Physical properties 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 See more Concentration units All discussions of radon concentrations in the environment refer to Rn. While the average rate of … See more In mines Radon-222 decay products have been classified by the International Agency for Research on Cancer as … See more • Radon and radon publications at the United States Environmental Protection Agency • National Radon Program Services hosted by Kansas State University See more Radon was the fifth radioactive element to be discovered, in 1899 by Ernest Rutherford and Robert B. Owens at McGill University in Montreal, after uranium, thorium, radium, and polonium. In 1899, Pierre and Marie Curie observed that the gas emitted by … See more Medical An early-20th-century form of quackery was the treatment of maladies in a radiotorium. It was a small, sealed room for patients to be exposed to radon for its "medicinal effects". The carcinogenic nature of radon due to its ionizing … See more • Chemistry portal • International Radon Project • Lucas cell • Pleochroic halo (aka: Radiohalo) • Radiation Exposure Compensation Act See more WebWhen radon gas is allowed to build up in an enclosed space, such as a mine shaft or basement, the radioactive hazard increases enormously because of the build-up of radon progeny. Conversely, when radon gas migrates through the atmosphere, the solid radon progeny are deposited on the soil and water below, entering into the food chain and hence … WebRadon is the product of the radioactive decay of the element radium. Indeed, radon is midway in a chain of radioactive transformations originating with uranium (which has such a long “half-life” that one-half of the earth’s original compliment remains.)
