Immediately after the discovery of the radioactivity of radon, near 1900.
Radon was discovered in 1900 by Friedrich Ernst Dorn, a German chemist.

Radon is a naturally occurring gas which in high concentrations can be extremely hazardous. So it it better to do the testing if you suspect the presence.
Radon was first discovered by Pierre and Marie Curie in 1899 in France. A year later Friedrich Dorn discovered it.
Radon does not have a traditional alchemy symbol as it was not known at the time when alchemy symbols were used. Radon is a radioactive gas and a chemical element with the symbol Rn and atomic number 86.
Radon was discovered by Friedrich Ernst Dorn, a German chemist, in 1900 while studying radium's decay chain
Yes, Dimitri Mendeleev (1834-1907) was alive during the discovery of radon (1899-1903).
Yes, home radon abatement is a specialized field, called "Health Physics". The main job of this Health Physicist is to protect you and your home from the potentially hazardous radon, as well as manage the good things about the use of ionizing radiation.

Radon is the heaviest of the inert gases. The inert gases are also known as the noble gases and are the lightest elements.
Stanley Watras discovered that radon was a health hazard in 1984 when high levels of radon gas were found in his home in Boyertown, Pennsylvania. This discovery led to increased awareness of radon and its potential health risks to humans.
Radon was discovered by Friedrich Ernst Dorn in 1898. There were several proposed names but finally in 1920 it came to be known as radon.
