Description:
The report gives results of radon mitigation research conducted in 1991 and 1992 in school buildings in Maryland, New Jersey, and Virginia. One school in each state was selected. In two schools, the objective was to evaluate the potential for modifying the school ventilation system to control radon concentrations. In the other school, newly constructed with radon resistant features, the objective was to evaluate the effectiveness of those features. The Paramount Elementary School in Hagerstown, MD, was selected because it was a typical older school with a modified unit ventilator heating, ventilating, and air-conditioning (HVAC) system. The Dranes Elementary School in Herndon, VA, was selected because it had a modern variable air volume (VAV) HVAC system that could be compared with a standard active subslab depressurization (ASD) radon mitigation technique. The Francis A. Desmares Elementary School near Flemington, NJ, completed in September 1991, selected because its 1989 building design included a rough-in of an ASD system with 10 stacks and a network of perforated pipes in the subslab aggregate.
