Radon is colorless at standard temperature and pressure and it is the most dense gas known. It was first discovered by Frederich Ernest Dorn in 1900. Dorn reported some experiments in which he noticed that radium compounds emanate a radioactive gas he named Radium Emanation (Ra Em).In 1910, Sir William Ramsay and Robert Whytlaw-Gray isolated radon, determined its density, and determined that it was the heaviest known gas. In 1923 this element was renamed radon. The element symbol for radon is Rn. The name radon came from radium.  Radon is used in hospitals for therapeutic reasons. Radon occurs in the environment mainly in the gaseous phase. Consequently, people are mainly exposed to radon through breathing air.They pump radium and seal it in needle but hospitals stopped doing this because they can purchase needles from suppliers. The first major studies with radon and health occurred in the context of uranium mining in the Joachimsthal region of Bohemia.When handling radon people should be extremely careful because when inhaled it could cause health concerns or even death.
