Assessment and Mitigation of Indoor Radon Problem: A Case Book for Radon Professionals

This chapter provides a comprehensive discussion on the nature of radon problem using relevant literature. This chapter emphasizes details on the aspects of radon formation, units of measurement for radon, pathways for radon entry into homes and the influencing factors, radon monitoring techniques, radon action levels, health effects of radon exposure, and control measures to reduce in-house radon exposure.

This chapter provides extensive details on the problem of radon in Ohio, USA by developing and analyzing the associated geospatial maps and statistical metrics. The geospatial and statistical analyses are examined at both the county level and the zip code level to have a thorough understanding of the radon problem that assists in accurately assessing the radon problem in reference to a specific location.

This chapter provides detailed information regarding the ²²²Rn problem in each of the 88 counties in Ohio by using the GIS based ²²²Rn GM concentration maps and computing different statistical metrics. The geospatial and statistical analyses are examined at a county level in great detail for all the available 88 counties in Ohio that assists in accurately assessing the radon problem in Ohio at a more microscopic level in reference to a specific location.

This chapter provides details on the mitigation of ²²²Rn concentrations in Ohio, USA through development of associated geospatial maps and computation of statistical metrics. The geospatial and statistical analyses are examined at both the county level and the zip code level to have a thorough understanding of the ²²²Rn mitigation that assists in accurately estimating the influence of adopted mitigation systems in controlling the in-house ²²²Rn concentrations. Additionally, a novel approach to rank the performance of different mitigation systems has been developed. The developed methodology, incorporated in this chapter is used to identify the best performing mitigation system in Ohio and serves as a case study for radon mitigation specialists in ranking their respective mitigation systems.

This book provided a comprehensive review of the 222Rn problem in Ohio homes complimented with an analysis on the performance of installed mitigation systems by documenting different statistical metrics and GIS-based maps on a county level basis and a zip code level basis for the state of Ohio.
