  Radon Prevention in the Design and Construction of Schools and Other Large Buildings (PDF) (50 pp, 4.14 MB) (EPA/625/R-92/016) June 1994

It is typically easier and much less expensive to design and construct a new building with radon-resistant or easy-to-mitigate features than to add these features after the building is completed and occupied. Therefore, when building in an area with the potential for elevated radon levels, architects and engineers should use a combination of radon prevention construction techniques.

To determine whether your building site is located in a radon-prone area, consult your EPA regional office or state or local radiation office. EPA recommends the following radon prevention techniques for construction of schools and other large buildings in radon-prone areas:

  • Install an active soil depressurization system
  • Pressurize the building using the heating, ventilating, and air conditioning system
  • Seal major radon entry routes

This manual details specific guidelines on how to incorporate these radon prevention features in the design and construction of schools and other large buildings.

Chapter 1 is a general introduction for those who need background information on the indoor radon problem and the techniques currently being studied and applied for radon prevention. The level of detail is aimed at developing the reader's understanding of underlying principles and might best be used by school officials or by architects and engineers who need a basic introduction.

Chapter 2 provides comprehensive information, instructions, and guidelines about the topics and construction techniques discussed in Chapter 1. The sections in Chapter 2 contain much more technical detail and may be best used by the architects, engineers, and builders responsible for the specific construction details.
