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 one of a number of intermediate radioactive elements formed during the radioactive decay of uranium-238, uranium-235 or thorium-232 isotopes to form stable, non-radioactive isotopes of lead. Radon-222 is the radon isotope of most concern to public health because of its longer half-life (3.8 days).It is one of the decay products of uranium-238. It is formed by the radioactive decay of its immediate âparent isotopeâ radium-226 (1620-year half-life).adon-In its natural state radon is an odorless, colorless, tasteless, radioactive gas. It is the only naturally radioactive gas and is the heaviest of all of the elements that occur as gasses at room temperature and pressure conditions.
