Commercial and home radon inpsections for Dayton and the rest of Southwest Ohio.


Radon and radon decay product concentrations in a dwelling fluctuate from hour to hour, day to day and 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 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 determine better 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 is turned off or the inlet closed. Fireplaces or wood stoves are not operated, unless they are a primary heat source. Whole house fans are not operated. Window fans are removed or sealed shut.

  • These test conditions are maintained for 12 hours prior to the start of the radon detector being exposed, unless the test is longer than four days in duration.

  • If there are any questions, or test conditions are not met, please contact the test company at (Co. Ph #)
