|Radon - Rn.|
Radon is the most dense gas known - My wife could've told them that.
Radon can be found in some spring water and hot springs - Aaaaaaahh!
People are mainly exposed to radon through breathing air - Now you're screwed. I've gotcha!
Radon enters the buildings through cracks in the foundations and basements - You can't keep me out.
