Q: The World Health Organization (WHO) just lowered its recommended radon tolerances below the EPA's. Should we be worried?
The WHO just dropped their recommended or acceptable radon levels to 2.7 picocuries per liter, which is below the 4 picocuries per liter recommended as the limit by the EPA. Should we be concerned? Is the EPA's standard good enough? What should we do if our basement isn't below the 2.7 picocuries per liter recommended by the WHO?
