Properties of Radon-222 Rn-222 is a by product of the decay chain of Uranium-238 that could be contained in the rock or soil where your house or building is built. Uranium-238 decays to Radium-226 which furthers decay to Rn-222.

As early as the 1500s, Agricola chronicled unusually high mortality from respiratory disease among underground metal miners in the Erz Mountains of eastern Europe ( Hoover and Hoover 1950 ).

Radon-222 is part of the uranium-238 radioactive decay chain. It is the immediate decay product of radium-226 which in turn is the radioactive decay product of primordial uranium-238 (half-life 4.5 billion years). Radon-222 has a half-life of 3.8 days and has a number of short-lived chemically reactive decay products that decay by alpha and

Radon-222 is formed naturally during a chain of radioactive decay. The decay series begins with uranium-238, and among the substances formed is radium-226, which decays directly to radon-222.

There is some potential of over-estimating the amount of Radon (Rn222) in a measurement by inadvertently including the decays from thoron (Rn220) and its decay products. Radon sniffing diagnostic measurements taken close to a radon entry route with a scintillation cell detector are particularly sensitive to this problem.

Radon-222 is the decay product of radium-226. Radon-222 and its parent, radium-226, are part of the long decay chain for uranium-238. Since uranium is essentially ubiquitous (being or seeming to be everywhere at the same time) in the earth's crust, radium-226 and radon-222 are present in almost all rock and all soil and water..
