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.) THE NATURAL RADIOACTIVE DECAY CHAIN R = radiation (alpha, beta, and gamma emissions) WebRadon (radon 222) is the sixth element in the radioactive decay chain of 238 U, one of the major natural isotopes on earth. Radon gas poses an environmental risk because of its …

WebAll RadonAway fans are known throughout the international radon industry for their unsurpassed quality, durability, and reliability. A few years ago, RadonAway introduced Pro Series radon fans for radon professionals, meeting the aesthetic needs of the radon community and their customers. 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.

WebRadon gas, 222Rn, is a problem in many buildings. The radon gas is not harmful in itself, but the decay chain contains charged elements such as 218Po, and 214Po ions which have a tendency to stick ... WebThe radioactive noble gas radon-222, characterised by a halflife of approximately 3.8 days, is produced by the alpha disintegration of radium-226 in the uranium-238 decay chain. WebAlpha decays of two radioisotopes in the decay chain, polonium-218 and polonium-214, deliver the energy to target cells in the respiratory epithelium that is considered to cause radon-associated lung cancer (NRC et al. 1999).
