What type of residences does the standard of practice specify procedures for measuring radon concentrations?

The standard of practice specifies procedures for measuring radon concentrations primarily in single-family residences due to the typical residential structures' relevance and their increased likelihood of being occupied. Single-family homes often face unique ventilation and structural challenges affecting radon levels, making targeted measurement protocols essential for effective assessment. This focus allows for a comprehensive understanding of radon risk in environments primarily inhabited by individuals and families.

While multi-family dwellings and commercial properties do pose measurable radon risks, the procedures for these types of buildings can differ due to varying occupancy patterns and structural designs. Vacant land, on the other hand, does not require measurement procedures as it inherently lacks structures that could concentrate radon gas indoors. Therefore, the emphasis on single-family residences is critical for establishing a baseline for radon measurement practices.
