Radon is obtained as a by-product of uraniferous ores processing after transferring into 1% solutions of hydrochloric or hydrobromic acids. The gas mixture extracted from the solutions contains H 2, O 2, He, Rn, CO 2, H 2 O and hydrocarbons. The mixture is purified by passing it over copper at 993 K (720 °C; … See more 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 … 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 … See more • Chemistry portal • International Radon Project • Lucas cell • Pleochroic halo (aka: Radiohalo) 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 monatomic gas with a density of 9.73 kg/m , about 8 … 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 being carcinogenic to humans, and as a gas that can be inhaled, lung cancer is a particular concern for people exposed … See more

WebRadon was discovered by Friedrich Ernst Dorn, a German chemist, in 1900 while studying radium's decay chain. Originally named niton after the Latin word for shining, nitens, radon … Webdifferent input images and compares this with the result obtained using the Radon transform found in MATLAB.

Radium and radon in the environment - Wikipedia

WebRadon is by far the largest contributor to the radiation exposure of populations, and most of that exposure takes place at home. For this reason, the great majority of radon measurements are ... at 7.7 MeV), a fast response time can be obtained. The response time of the instrument also WebRadon is a naturally occurring radioactive gas and comes from the natural breakdown (radioactive decay) of uranium. It is usually found in igneous rock and soil, but in some … WebJan 4, 2024 · You can start by testing radon levels in your home and installing a radon reduction system, if needed.
