96 Hour Rule – 422.130.(b)(D)

Short-term measurements of less than 96 hours shall not be conducted during severe storms or    periods of sustained high winds (30 miles per hour or more). Radon Measurement licensees shall check and document local weather forecasts prior to placing short-term measurement devices when the measurement period is less than 96 hours.

32 ILAC 422.130.(b)(D)

AGENCY NOTE: The National Weather Service defines a severe storm as a storm that generates winds of 58 mph and/or ¾-inch diameter hail and that may produce tornadoes – not necessarily in that order.

Think about it

How many 96-hour-or-less radon tests have you re-scheduled due to weather interference? How many sellers may have suffered financial ramification due to “false-high” results?
