The report is a reference manual for RASSMIT Version 2.1, a computer program that was developed to simulate and aid in the design of sub-slab depressurization systems used for indoor radon mitigation. The program was designed to run on DOS-compatible personal computers to ensure broad applicability as a design tool for these mitigation systems. The program addresses both major techniques for using sub-slab depressurization in slab-on-grade construction: discrete suction pits and extended suction systems. Discrete pit suction systems are applicable to both retrofit mitigation systems in existing houses, and new house construction. Extended suction systems use some form of highly porous material, most typically drainage mat or large aggregate, to extend the suction over large distances below concrete slabs. These systems must be installed prior to pouring the slab and are therefore applicable only to new house construction. The program provides a menu-driven scheme to design and evaluate these indoor radon mitigation systems for houses utilizing slab-on-grade construction techniques over low permeability soil and fill material.
