If the radon level in a residential 1 family, ranch styled house (with crawl space beneath the house) is 113 pCi/L how can a tester determine the radon level emitted from the exterior ground outside the house?
My client is concerned about her dog (small hound dog that constantly is sniffing the ground and only stands 6" off the ground) and her very young children that play on the ground outside the house and take naps on blankets lying flat on the ground.
Although I'm sure there is natural remediation of radon emitted from the ground when it mixes with ambient air, but how can she be sure that the level of radon in the air that will likely be inhaled by pets and children is not a dangerous level. What I'm looking for is an E.P.A. approved method to test or verifiable data that has been accumulated by reputable a source(s).
