What document specifies procedures for determining if mitigation is necessary in single-family dwellings?

The appropriate document that outlines procedures for determining if mitigation is necessary in single-family dwellings is referred to as "Measurement of Air in Homes" (MAH). This document provides guidance on how to assess radon levels in residential settings, including single-family homes, and establishes thresholds that dictate whether mitigation efforts are needed based on indoor radon concentrations.

Typically, the MAH will lay out specific measurement protocols and acceptable radon levels, which serve as benchmarks for making informed decisions about the need for mitigation. The focus on actual measurement of radon levels in residential air helps ensure that home environments are safe for occupants.

While other documents may address related concepts such as testing protocols and strategies for mitigation or general building health standards, MAH specifically connects the measurement process with actionable outcomes regarding the necessity of mitigation in response to detected radon levels. This is critical for ensuring that responses to radon exposure are based on accurate, evidence-based assessments.
