Craftsman Home Inspection 401-246-1770 NON-INTERFERENCE RADON TEST AGREEMENT
Radon and radon decay product concentrations in a dwelling fluctuate from hour to hour, from day to day and from season to season. The following test recommendations were developed by the EPA to provide standardized conditions under which a short-term radon survey is to be performed in order to reduce the variation in radon levels in a dwelling. These conditions will tend to maximize the radon measurement in order to determine if a dwelling has the “potential” to have an elevated radon level. If the result is elevated, the EPA recommends further testing to better determine the yearly average concentration. If the test conditions below are not adhered to, the test results may be deemed invalid. The following conditions must be read, understood and followed: All exterior windows must be kept closed. All exterior and the basement to first floor doors must be kept closed except for normal, momentary entering and exiting. The radon detector cannot be moved, covered or altered in any way. Heating, air conditioning, dryers, range hoods, bathroom fans and attic ventilators can be operated normally. If any heating, air conditioning or ventilating equipment has a built in outdoor air supply that is manually controlled, it shall be turned off or the inlet closed. Fireplaces or wood stoves shall not be operated, unless they are a primary heat source. Whole house fans shall not be operated. Window fans shall be removed or sealed shut. These test conditions shall be maintained for at least four days. Tests can be run just under seven days.
