Environment Radon Effects In human

Radon gas with symbol Rn, under standard conditions, is the densest gas in the world. Below the freezing point, it is a yellow, phosphorescence brilliant chemical substance which is intensively radioactive with a short half life. It is capable of ionizing radiation emitting α, β, γ rays, which is occasionally used for medical treatments.It is usually kept inside gold vials for carrying.Because of the very short half life of Radon, it decays fast in the atmosphere. Thus, it could be used for geological and atmospheric studies. Generally, there is detectable amount of Radon found in some spring waters and hot springs as well as the atmosphere. One gram of Radium- 226 contains 0.0001 cc dose of Radon. This paper will review the radioactivity properties of Radon gas as well as its physicalchemicalproperties for biological studies intending to point out the epidemiological evidence about the relation between the inhalation of this gas and health problems.
