Radon-222 is one of the isotopes or the inert gas radon. It is the longest-lived occurring one, and it appears as a daughter of the radioactive decay of radium (226Ra). It is radioactive (as are all of radon's isotopes), and, as such presents a hazard to people. The 222Ra isotope undergoes alpha decay to become polonium-218 (218Po). It is uranium that is the culprit as regards the source of radon. Uranium is the source of radium, and from radium we see radon. Uranium is present in the ground in a number of types of rock, so radon could appear in soil samples, in ground water, or in the lower internal spaces in buildings (because is seeps in). Radon is considered to be the second leading cause of lung cancer, and is an underrated threat. Testing for radon in structures is a bit tedious, but it can be done. If there is a question about a radon threat to your home, testing is not outrageously expensive. Call your county health office and get a "threat assessment" for your area. Just remember that though your neighbor's house might be well under recommended limits, yours may not, as there are variables to consider. Use the link below for more information.

Hyphen notation for Radon?
The hyphen notation for Radon is Rn-222.
Which elements atomic mass is 222 amu?
The element with an atomic mass of 222 amu is radon (Rn).
Is radon 222 an indoor particle?
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.
What other isotope are in radon 222?
none
What is the greater source of indoor polution?
radon 222
What is the decay process does radium 226 undergo including the nuclear changes that occur?
Radium-226--------------------Radon-222 + alpha
How many days are required for 200 grams of radon-222 to decay to 50 grams?
7.64 it is the half life of radon-222 multipled by 2
What is the element radon's isotopes?
Radon has four main isotopes: 210Rn, 211Rn, 222Rn, and 224Rn. Radon-222 is the most stable form.
When radium -226 decays to form radon -222 the radium nucleus emits?
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
What is a common compound found that includes radon?
radon is a noble gas, so it does not form compounds.
What element Nobel gas with atomic mass of 226?
Radon has atomic mass of 222. There is isotope of Radon with mass number 226. Radon is a Nobel gas.
How does radon-222 decay by alpha emission?
Radon-222 decays by alpha emission through the release of a helium nucleus, which consists of two protons and two neutrons. This process reduces the atomic number of the radon atom by 2 and the atomic mass by 4.
