Abstract
This paper will discuss current and proposed American (AARST) and Canadian (CARST) protocols regarding radon measurements for real estate transactions. Expectations and understanding of the real estate industry in both countries will also be presented; as will general practice within the “home inspection” profession; along with mitigation and escrow implications.
A method will be proposed to improve the reliability of real estate transaction radon measurements. A key feature of the method is the deployment of three “listed” detectors (any type capable of providing short term results) in nominally the same physical location, such that they are subject to equivalent temporal, seasonal, and environmental conditions over the course of the measurement period. The three resulting radon concentration measurements are then analyzed using the Dixon Criterion, a statistical method specifically designed for maintaining precision in small data sets by providing a statistical basis for the rejection of an “outlier” or suspect result.
