Comparison of Two Day Consecutive Radon Measurement Results to a 90 Day Average Measurement Results Using the Data from Continuous Radon Monitors in a Typical Single Family Home in Frederick, Md, Usa

Two calibrated Radon Scout continuous radon monitors were installed in the basement of a typical single family home in Frederick, MD, USA, in accordance with the USEPA deployment protocols. These units were set to collect and average radon concentrations over three hour intervals. In addition to logging the average radon concentrations, the basement temperature, humidity, and barometric pressures were also collected. The units were run for three months in closed house conditions. The data was analyzed with an aim to find any correlation of three hourly peaks to outdoor environmental conditions such as precipitation, temperature, and wind. Further aim was to determine how the two day consecutive average radon concentrations compare with the three month average radon concentrations. This work describes the results for the first two quarters of 2010 and will continue for the entire year. This may answer some frequently faced queries by the radon measurement professionals, in the course of their work.
