Sejarah
Radon was discovered in 1900 by Friedrich Ernst Dorn in Halle, Germany.

He reported some experiments in which he noticed that radium compounds emanate a radioactive gas.

In 1910, Sir William Ramsay and Robert Whytlaw-Gray isolated radon, determined its density, and determined that it was the heaviest known gas.

Aplikasi
Radon is used in hydrologic research that studies the interaction between ground water and streams.

Radon has been produced commercially for use in radiation therapy.

Radon has been used in implantable seeds, made of gold or glass, primarily used to treat cancers.
Radon is highly radioactive and a carcinogen
