No. = Number of radon tests done in a zip code, Max = Maximum radon concentration measured in the zip code
Min = Minimum radon concentration measured in the zip code, AM = Arithmetic
mean radon concentration
GM = Geometric mean radon concentration, SD = Standard deviation, CV
=Coefficient of variation
Md = Median of radon concentration, Q1 = First quartile of radon concentration,
Q3 = Third quartile of radon concentration
All concentrations are in units of pico-Curies of radiation per liter
of air ( pCi/l ).
Note: The statistics are based on 207,968 data points for 1458 zip codes.
