El radón es un gas radiactivo de origen natural, que tiende a concentrarse en interiores, como en viviendas y lugares de trabajo.

Radon-222 is a gas produced by the decay of radium-226. In the context of radiation, epidemiology is concerned with the establishment of statistical associations between exposures and health effects. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. It is transient in the decay chain of primordial uranium-238 and is the immediate decay product of radium-226.Radon-222 was first observed in 1899, and was identified as an isotope of a new element several years later. THE HEALTH EFFECTS OF INHALED RADON AND ITS PROGENY (29) Estimates of the consequences to health of exposures to ionising radiation are best based on epidemiological studies of human populations. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here. Among them, radon-222 (radon) and radon-220 (thoron) are of practical significance. Radon-222 (222 Rn, Rn-222, historically radium emanation or radon) is one of the most stable isotopes of radon, with a half-life of approximately 3.8 days. If you think your health has been affected by exposure to radon, contact your health care professional. See also: Radon – Health Effects Radon-222 Uranium Series – Source of radon-222. Health Effects From Radon – Radon is the leading ‘environmental’ cause for cancer, meaning that of all cancers caused by the environment in mankind radon causes the most cancers. THE HEALTH EFFECTS OF INHALED RADON AND ITS PROGENY (29) Estimates of the consequences to health of exposures to ionising radiation are best based on epidemiological studies of human populations.

It is estimated that radon causes between 3–14% of all lung cancers in a country, depending on the average radon level and the smoking prevalence in a country. This site uses cookies. Since uranium is found in soil throughout the world in varying concentrations, also dose from gaseous radon is varying throughout the world. The major source for exposure to radon is the air inside homes we live. PROTECTION AGAINST RADON-222 7 2. To find out more, see our Privacy and Cookies policy. All isotopes of radon are radioactive , but the two radon isotopes radon-222 and radon-220 are very important from radiation protection point of view. Radon RN-222. The dust is trapped in our airways and emits radiation that damages the inside of our lungs. An increased rate of lung cancer was first seen in uranium miners exposed to high concentrations of radon.
