A tool used to determine the appropriate size of a mitigation device employed in reducing airborne radioactive gas concentrations within a building is described. This instrument analyzes various factors, including sub-slab aggregate permeability, building foundation size, and desired pressure differential, to estimate the required airflow for effective extraction of the gas. A larger foundation, for example, typically necessitates a higher-capacity mitigation device.
Accurate selection of this component is paramount for ensuring optimal system performance and minimizing energy consumption. Historically, over-sizing these components was common, leading to unnecessary energy waste and potential noise issues. Properly assessing the necessary specifications provides for efficient and effective remediation, leading to improved indoor air quality and reduced risks associated with long-term exposure to this naturally occurring element.
