Example of newly developed map showing radon danger levels based on home testing and geologic data in the state of Kentucky, USA to illustrate radon risk potential. Radon levels by rock type (pCi/L) ranged from 0.0–2.7 (blue), 2.71–4.0 (green), 4.01–8.0 (yellow), 8.01–16.00 (brown), 16.01–25.30 (red).
