Radon tests reported for King and Queen County, 2008 to 2017, laboratory
CDC holds 7 reported tests for King and Queen County over the 2008 to 2017 laboratory totals, with a median of 2.4 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). King and Queen County beside the counties around it is how this page reads it.
What these figures count
Only 7 tests were reported to CDC for King and Queen County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.
Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
