ANSI/AARST standards are national consensus standards developed for every building type.

Radon can enter buildings through soil, water, or building materials — and each structure presents unique challenges.

These standards provide consistent guidance for radon measurement and mitigation in residential, multifamily, commercial, and large buildings.

Standardized approaches help ensure protection for occupants, regardless of building design or use.

Why do ANSI/AARST radon standards matter?

Radon exposure is a public health issue that requires consistent, science-based approaches to measurement, mitigation, and long-term stewardship.

ANSI/AARST standards establish nationally recognized best practices to help ensure radon concentrations in buildings remain below the EPA Action Level.

These standards provide a common framework professionals can rely on to protect building occupants across all building types.
