What are the testing protocols?
EPA has issued “protocols” or guidelines for radon testing in the home as well as for testing associated with real estate transactions. The testing procedures or protocols that are used when a house is being tested in connection with a real estate sale, are listed in the “Home Buyer’s and Seller’s Guide to Radon” (EPA 402-K-00-008, July 2000). The standard protocols are provided in “A Citizen’s Guide to Radon” (EPA 402-K92-001, May 1992) This guide provides protocols for both short and long-term radon testing.
