Radon Testing Results

Testing was done in each school January 17 through January 20, 2017. The sampling was performed by Fuss & O’Neill EnviroScience, LLC in response to Connecticut General Statute Section 10-220. The sampling followed the protocols of EPA Radon Measurement in Schools, EPA 402-R-92-014. The 2017 sampling serves to meet the five-year cycle requirement for Region 12 School District. The test results showed that we are in compliance

Below is the conclusion of the radon testing from Fuss & O’Neill EnviroScience.




During the course of the initial radon air sampling in the Region 12 schools, thirty-six (36) sampling canisters, including duplicates and blanks, were placed in 10% of every frequently occupied room that is either located on ground level, or over a room, or space that touches the ground, but does not meet the EPA/CTDPH criteria of "frequently occupied". All canisters were found to be in place and undisturbed when EnviroScience retrieved the canisters. Sample collection complied with CTDPH and EPA requirements. The RPD was not calculated, since in each duplicate pair, both results were below the 4.0 pCi/L standard, as adjusted for the canister error rate. The 'blank' sampling canisters did not exceed a level that would question the validity of the radon air sampling.

The average outdoor radon concentration as studied by the EPA is 0.4 pCi/L and the average indoor concentration is 1.3 pCi/L. The EPA has a recommended action guideline of 4.0 pCi/L and recommends taking further action (fixing the problem) if results are over 4.0 pCi/L. The results for the Region 12 School District sampling were all below the average EPA standard and are not of concern for the sampling dates.
