Tipper's take on radon in Sultana
Sultana is in Tulare County, EPA Zone 2, a moderate risk classification. The EPA predicts average indoor radon levels between 2 and 4 pCi/L here. CDC data from Tulare County puts the average measured radon level at 3 pCi/L.
"Moderate" is the zone people underestimate most. Some homes in Sultana will test at 1 pCi/L, others at 7 pCi/L. The county average doesn't tell you which side your home falls on.
A $15 test kit answers the question for good. If you're below 4 pCi/L, you can stop thinking about it. If you're above, mitigation systems in California typically cost $800–$2,000 and work well.
