Radon is a gas produced by the natural decay of radium. Radium is found in trace amounts in a great many places, and normally radon gas is not a problem. However, since it is a very heavy gas, it tends to collect in places like basements where it can become relatively concentrated and a health hazard. The remedy is simply to provide some ventilation for the basement.

i think it is not Randon it is Radon.
Radon (IPA: /ˈreɪdɒn/) is a chemical element in the periodic table that has the symbol Rn and atomic number 86. A radioactive noble gas that is formed by the disintegration of radium, radon is one of the heaviest gases and is considered to be a health hazard. The most stable isotope is Rn-222 which has a half-life of 3.8 days and is used in radiotherapy. Radon gas can accumulate in buildings, and drinking water, and cause lung cancer [1], causing potentially 20,000 deaths in the European Union each year. Radon is a significant contaminant that impacts indoor air quality worldwide.

The battle of Châteauneuf-de-Randon was fought in 1380 between the English and the French. In 1380 the fortress of Châteauneuf-de-Randon was besieged by the French, under the command of Du Guesclin, and the fortress was defended by an English garrison under De Ros. After a defence that obstinate, the town surrendered on July 4th. The siege however, was fatal to the French commander

Hi. Do you mean radon, the radioactive gas emitted by soil?

FIRSTLY IT'S RADON.
ITS A COLOURLESS GAS THAT BUILDS UP UNDER IMPERMIABLE ROCK (MAINLY GRANITE) AND CAUSES RADIATION POSINING. HOWEVER IT CAN BE DISPERSED BY CROSS VENTELATION UNDER THE BUILDING, RADON PROOF MEMBRANE IN THE CONCRETE OR A RADON SUMP UNDER THE HOUSE WHICH SUCKS IT UP AND PUMPS IT OUT OF THE ROOF
