RADON IS A COLORLESS , ODORLESS, TASTELESS RADIOACTIVE INVISIBLE GAS THAT COMES FROM THE SOIL- NOT THE HOME, NO HOME IS EXEMPT FROM THE POTENTIAL TO HAVE RADON, IN FACT MOST HOMES WILL HAVE SOME.

RADON GAS IS PRODUCED FROM THE NATURAL BREAKDOWN OF URANIUM IN SOIL , ROCK AND WATER, IT IS LIGHTER THAN AIR AND MOVES UP INTO THE HOME THROUGH CRACKS AND HOLES IN THE FOUNDATION; ANY PLACE WATER SEEPAGE CAN BE FOUND IS A POSSIBLE ENTRY POINT FOR RADON GAS AS WELL. ABOUT 38% OF HOMESIN CHICAGOLAND AREA WERE FOUND TO HAVE ELEVATED LEVELS OF RADON.
 
RADON IS A CLASS A CARCINOGEN THAT IS KNOWN TO CAUSE LUNG CANCER IN HUMANS, AND IS THE LEADING CAUSE AMONG PEOPLE WHO NEVER SMOKED. SECOND ONLY TO SMOKING AS THE NUMBER ONE CAUSE. IT IS ESTIMATED TO CAUSE BETWEEN 15,000 TO 22,000 LUNG CANCER DEATHS A YEAR.
 
IF IT IS FOUND IN LEVELS ABOVE 4pCiL YOUR HOME, IT CAN BE EASILY FIXED (MITIGATED) TO REDUCE LEVELS TO A MORE ACCEPTABLE RANGE. THE COST IS NOT MUCH MORE THAN A TYPICAL HOME REPAIR.
