Answer by  apsaras (408)

Radon-222 is an unstable radioactive isotope of radon, one of the noble gas. It has a half-life of around 3.8 days and decays into polonium-218. It is produced from the radioactive decay of radium-226. It is chemically inert and commonly used as a radioactive tracer.

222Rn (Radon 222) is a stable Radon isotope. Discovered by Marie Curie, Radon222 is a radioactive gas with an half-life of 4 days. Although used in radioterapy, it is toxic. Small amounts naturally occur in nature: in fact Radon can accumulate in some buildings. Being a gas, the best way to keep it out is to change frequently the air.
