Chemicals in cigarettes and cigarette smoke are known to cause not only cancer but also other serious health problems. Many of the chemicals are poisonous. If a person ate one pack of cigarettes, he/she would die.
Radon is a naturally occurring radioactive gas that is formed when uranium decays in the soil. Uranium is in geological formations throughout North Carolina. When homes or other buildings are built on top of these geological formations, radon is pulled into the home and can concentrate to dangerous levels.
Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas, occurring naturally as a decay product of radium. Its most stable isotope, 222Rn, has a half-life of 3.8 days.Radon is one of the densest substances that remains a gas under normal conditions.horium and uranium, their decay product radium, and its decay product radon, will therefore continue to occur for tens of millions of years at almost the same concentrations as they do now. As radon itself decays, it produces new radioactive elements called radon daughters or decay products.
