Radium occurs as a natural decay product of uranium present in various types of rocks. By the late s, naturally occurring radon gas had come to be recognized as a potentially serious health hazard.

Radioactive decay of uranium in minerals, especially granite , generates radon gas that can diffuse through soil and rock and enter buildings through basements radon has a higher density than air and through water supplies derived from wells radon has a significant solubility in water.

The gas can accumulate in the air of poorly ventilated houses. Exposure to high concentrations of this radon and its daughters over the course of many years can greatly increase the risk of developing lung cancer.

Indeed, radon is now thought to be the greatest cause of lung cancer among nonsmokers in the United States. Radon levels are highest in homes built over geological formations that contain uranium mineral deposits.

Concentrated samples of radon are prepared synthetically for medical and research purposes. Typically, a supply of radium is kept in a glass vessel in an aqueous solution or in the form of a porous solid from which the radon can readily flow.

Every few days, the accumulated radon is pumped off, purified, and compressed into a small tube, which is then sealed and removed.

Such tubes of radon have been used for radiation therapy and radiography. Natural radon consists of three isotopes, one from each of the three natural radioactive-disintegration series the uranium , thorium , and actinium series.

Discovered in by German chemist Friedrich E. Dorn, radon 3. The name radon is sometimes reserved for this isotope to distinguish it from the other two natural isotopes, called thoron and actinon, because they originate in the thorium and the actinium series, respectively.

Radon thoron; Owens and Ernest Rutherford , who noticed that some of the radioactivity of thorium compounds could be blown away by breezes in the laboratory.

Radon actinon; 3. Show more products in this category. Hide suggestions. Please select. Calculate frame size. Suspension Setup.

Radon is a colourless, odourless radioactive gas. The main danger from high radon exposure is the increased risk of lung cancer.

For most people, radon is the single largest source of radiation exposure whether they are at home or at work.

PHE provides resources and advice about radon for the public, including individual householders, industry, education and research.

Radon atoms possess a particularly stable electronic configuration of eight electrons in the outer shell, which accounts for the characteristic chemical inactivity of the element.

Radon, however, is not chemically inert. For example, the existence of the compound radon difluoride, which is apparently more stable chemically than compounds of the other reactive noble gases, krypton and xenon , was established in The products of these fluorination reactions have not been analyzed in detail because of their small masses and intense radioactivity.

Nevertheless, by comparing reactions of radon with those of krypton and xenon it has been possible to deduce that radon forms a difluoride, RnF 2 , and derivatives of the difluoride.

The chemical behaviour of radon is similar to that of a metal fluoride and is consistent with its position in the periodic table as a metalloid element.

The presence of radon gas as a member of the uranium-decay scheme provides a unique method for creating disequilibrium. The gas radon Rn escapes from the ground and decays rapidly in the atmosphere to lead Pb , which falls quickly to the surface where it is incorporated in glacial….
