MAMF/MALB Companion Guidance 2021 Section 2 Guidance to Building Managers 4 — Who is designated to receive data or reports from the radon measurement professional. — What situations, if any, warrant reporting interim and incomplete test results prior to completion of all test phases. This should be decided prior to any situation where follow-up testing is a component of the chosen test strategy. • Identify who is responsible for developing contingency plans for unexpected challenges during the testing. • Identify who is granted permission to respond to public inquiries. • Specify the procedure and mechanism for disclosing the radon test results and the person(s) allowed to discuss test results with occupants, parents or other parties. Pre-test notifications Distribute notices of radon testing at least two weeks in advance of beginning testing and again a few days before the test to appropriate staff and occupants. Poor communications prior to testing can lead to test disruption and unusable data, creating unnecessary expense and aggravation. Note— Section 2.6 and Exhibits 2 through 5 provide details and sample notification forms. After the test – A Recommendation Full public disclosure of radon test results for large buildings is strongly recommended and in some localities required by law. Failure to disclose test results can deprive current and future occupants of information necessary to avoid risk, thereby increasing the culpability of building owners and managers. C. Selecting a Radon Measurement Professional The goal is to select a radon measurement professional who will provide reliable services and procedures. Use experienced professionals that have demonstrated a minimum degree of appropriate technical knowledge and skills both sufficient to place, retrieve and analyze (as applicable) radon detectors and to design, plan, and implement quality procedures when conducting radon measurements. Test devices: All equipment used for measuring radon must meet requirements of the local jurisdiction or be listed by a nationally recognized radon proficiency program if the jurisdiction has no device verification program. D. Role of a Facility’s Personnel Because the facility's personnel frequently have knowledge of the building and the occupants, they can play a key role during the testing process, especially in planning and efficient use of professional services. By providing floor plan diagrams, when available, and timely access to rooms, the facility personnel can help the radon measurement professional to quickly plan the testing strategy and achieve reliable results. It is strongly recommended that untrained personnel serve only in these support roles for trained and certified or licensed radon measurement professionals. Specific training that includes demonstration of proficiency in the use of detectors should be obtained prior to assisting a qualified radon measurement professional in placing and retrieving detectors. E. Documenting the Testing Program The building managers or owners should maintain a record of the testing program for future reference. F. When to Test While testing at any time can provide valuable information, confidence that elevated radon concentrations are not present is best achieved with tests conducted during periods that reasonably represent: a) The normal occupied operating condition for the building or unique sector of the building. b) Testing periods when the operating conditions are most likely to emphasize a clear characterization of a radon hazard. Note—For most locations in the U.S., this would be during the heating season (e.g., winter). See Appendix A for more information.
