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 oxide is a compound that forms when radon gas reacts with oxygen. It is a radioactive compound and can be harmful if inhaled or ingested. Radon oxide is not commonly found in nature due to radon's short half-life.
Radon is not used for geological or paleontological dating.
It is a gas.
Radon is radioactive and is actually a fairly common hazard because of this.
The common form of radon is a colorless, odorless, and tasteless gas known as radon-222. It is a naturally occurring radioactive gas that is produced from the decay of uranium in soil, rock, and water.
radon is a noble gas, so it does not form compounds.
Radon is a naturally occurring radioactive gas that is produced from the decay of uranium in soil and rocks. It is found in the Earth's crust and can seep into buildings through cracks and openings in the foundation. This is why radon is still present in nature.
Although the atomic mass number of radon is often given as 220, there are 39 isotopes and isomers of radon. The common isomers of radon are : radon-219, radon-220, and radon-222.
Radon (Rn)
Radon is a naturally occurring element. It is a noble gas, and is highly unreactive. Radon is a poisonous gas and is the second most common reason people have lung cancer (behind smoking). Most radon comes from beneath the ground and as it rises up it can permeate through someone's home. This is why it is important to have radon detectors in geographical areas that have had a historically high concentration of radon.
In some regions, yes.
Radon-222 is a radioactive gas that is a natural byproduct of the decay of uranium in soil and rocks. It can seep into buildings through cracks in foundations and accumulate indoors. While not a particle itself, radon-222 can decay into solid radioactive particles called radon progeny, which can pose health risks when inhaled.
