Question

What is Radon? Should you worry about it?

Answer 1

radon is a gas, whose STABLE ISOTOPE wont harm you, although its radioisotopes would.

Explanation:

Exposure to the combination of radon gas and cigarette smoke creates a greater risk for lung cancer than either factor alone. Most radon-related lung cancers develop in smokers. However, radon is also thought to cause a significant number of lung cancer deaths among non-smokers in the United States each year.
