Radon-220 (thoron; 51.5-second half-life) was first observed in 1899 by American scientist Robert B. Owens and British scientist Ernest Rutherford, who noticed that some of the radioactivity of thorium compounds could be blown away by breezes in the laboratory.

Find mass (in kg) of radon is equivalent to 1 millicurie? An overview is available from MedlinePlus, a consumer health web site produced by the National Library of Medicine. Isotopes of radon, all having short half-lives, are formed by the radioactive decay of radium, actinium, and thorium. Three of the 37 known isotopes occur naturally - Rn-219, Rn-220 and Rn-222. The half-life of radon-222 is 3.8 days and it decays via alpha decay to polonium-218. Radon-220. The radon-220 isotope, commonly referred to as thoron, is a natural decay product of the most stable thorium isotope (thorium-232), thus it is a member of thorium series.
