In a geographical sense, just about everywhere. It is more common in certain areas than others. It's considerably heavier than air, so radon escaping from the ground into the atmosphere tends to collect in low places, particularly those which are enclosed and have little air circulation. Typically in a house the highest concentration of radon will be found in the basement.
Radon exist in all regions in the world but especially near uranium and thorium ores deposits.
Mean concentration of radon in air: 150 atoms/cm3
Radon in the earth crust: 4.10-16 mg/kg
Radon in the sea water: 6.10-19 mg/L
Radon is found in lightning, and other places of which I am unaware.
Radon is extracted from uranium and thorium minerals.
It's a decay product of other radioactive atoms in the ground.
The element, Radon is one of the Noble Gases like Helium and Neon that do not form compounds. Thus Radon is always found in the Pure State.
radon is a noble gas, so it does not form compounds.
Radon is a gas at room temperature, and quite a bit below it, too. A link can be found below.
No. Radon is a gas, and a very volatile one at that. The only place it can accumulate is in totally sealed basements.

Radon is a natural radioactive gas.
Radon is a natural radioactive gas.
Radon exist in rocks containing uranium or thorium.
Radon is a member of the noble gases group: helium, neon, argon, krypton, xenon, radon.
Near Radium.

Radon is a gas found in the air. It can cause lung cancer so beware!
radon is a noble gas, so it does not form compounds.
Element.
Radon is a natural chemical element; it can be found in the radioactive decay series of uranium and thorium.
Periodic table doesn't mention radon doses.
