RADON
Radon is a radioactive element with the symbol "Rn". It belongs to 18th group 6th period. It is a colorless, odorless and tasteless gas, liquefies at -61.8 ° C (-79.2 ° F) and freezes at -71 ° C (-96 ° F). The more cooled solid radon emits a color such as orange. It is one of the inert gases at normal temperatures. It is the densest of the inert gases. Its solubility in water is low; however, it dissolves more than light noble gases. Radon is a rare element because all of its isotopes are short-lived. Radon-222, the most stable isotope of radio, has a half-life of 3.8 days. In addition, radium, which is a source of radon, is rare in nature.
Radon, which is derived from the Latin words "niton" or "nitens" meaning "shining", was called radium when it was first discovered. However, in 1923 it started to be known as "radon".
Radon, which has a carcinogenic effect due to its radioactivity, can accumulate in houses and is a gas that has a lethal effect when necessary precautions are not taken. It has been declared that radon is the most dangerous substance after smoking that causes lung cancer. It is estimated that about 10 percent of all lung cancer cases in the world are caused by radon. It has been determined that it is stored in the lungs, triggering or accelerating cancer formation. In other words, it is a gas that causes lung cancer in the long term.
