Radon tests reported for Colonial Heights city, 2008 to 2017, laboratory
CDC holds 10 reported tests for Colonial Heights city over the 2008 to 2017 laboratory totals, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Colonial Heights city beside the counties around it is how this page reads it.
What these figures count
Only 10 tests were reported to CDC for Colonial Heights city 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).
