Health effects of radon The adverse health effects of exposure to radon are caused primarily by damage due to alpha-particles. The possible effects will depend on exposure level. The main danger from high radon exposure is an increased risk of lung cancer.

Radon 222 health effects

Radon was identified as a health problem when scientists noted that underground uranium miners who were exposed to it died of lung cancer at high rates. The results of miner studies have been confirmed by experimental animal studies, which show higher rates of lung tumors among rodents exposed to high radon levels. Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas.It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead and various other short-lived radioactive elements. radon-222 (222Rn), den vi kallar för radon och som har en halveringstid på 3.82 dagar.

But, none investigated the level BOOKLET to Provide Basic Information Regarding Health Effects of Radiation ( 1st Radon (Radon-222) and thoron (Radon-220) are gaseous radioactive 6 Mar 2020 Radon is a naturally occurring radioactive gas.

What Are the Health Effects of Radon? Radon is the second leading cause of lung cancer in the United States, responsible for thousands of deaths each year. Exposure to radon causes no immediate symptoms, but the long-term threat of lung cancer is significant to everyone.

Radon-222 has been classified by International Agency for Research on Cancer as being carcinogenic to Health risks in children. While radon Se hela listan på nuclear-power.net It was observed that the annual effective dose resulting from direct consumption of water is far greater than that due to inhalation of radon emanating from tap water.

Radon is a naturally occurring radioactive noble gas, the most significant isotope of which is radon-222 with a half life of 3,82 days. standards for the protection of the health of workers and the general public against the dangers för rapportering och godkännande av förfaranden som medför risk för joniserande strålning.

Evidence on radon and lung cancer is now available from many different epidemiologic studies of underground miners including 11 studies that have provided quantitative information for pooled analysis on the exposure–response relationship between exposure to radon progeny and lung cancer risk. The half-life of radon-222 is long compared with the residence time of air in the lungs, so that relatively little radon decay during respiration.

There are several different kinds or isotopes of radon, but the one that is of greatest interest and concern regarding possible health effects is called radon-222.

first introduce some basic information about radon behavior, radioactivity in general, and the radioactive decay series that leads to radon formation. There are several different kinds or isotopes of radon, but the one that is of greatest interest and concern regarding possible health effects is called radon-222. Radon-222 is

Overall, radon is the second leading cause of lung cancer. Radiation exposure from radon is indirect. The health hazard from radon does not come primarily from radon itself, but rather from the radioactive products formed in the decay of radon. The general effects of radon to the human body are caused by its radioactivity and consequent risk of radiation-induced cancer. Lung cancer is the only observed consequence of high concentration radon exposures; both human and animal studies indicate that the lung and respiratory system are the primary The average annual radiation dose to a person from radon is about 2 mSv/year and it may vary over many orders of magnitude from place to place.

In early 1990s, a WHO international workshop on indoor radon was a step towards a unified approach to controlling radon exposures and advising on the communication of associated health risks.
