Abstract The report describes the development of engineering design criteria for the successful design, installation, and operation of sub-slab depressurization systems, based on radon (Rn) mitigation experience on 14 slab-on-grade houses in South Central Florida. The Florida houses are characterized as being hard to mitigate because of low sub-slab permeabilities. Premitigation indoor Rn concentrations ranged from 10 to 100 pCi/L. Mitigation experience and results have been combined into tables and graphs that can be used to determine recommended numbers and placement criteria for suction holes. Fan and exhaust pipe size selection is assisted by other tabulated and derived information. Guidance for installation of the sub-slab system to enhance the system's operation and effectiveness is also provided. This guidance is reported in the form of a design manual for use by mitigators when they are dealing with houses similar to these.
