Radon, et al
Kansas State University: Is Radon a Real Problem?
The primary US standards for radon are developed by the Environmental Protection Agency (EPA), the American Association of Radon Scientists and Technologists (AARST), and ASTM International. These focus on measurement protocols, mitigation techniques, action levels, and construction guidelines to detect radon entry and prevent health risks like lung cancer. Below is a list of the top 10, prioritized by prominence in EPA guidance, adoption in building codes, and applicability to residential/commercial settings.

|
Standard
|
Issuing Body
|
Brief Description
|
|---|---|---|---|
|
1
|
EPA Action Level for Radon (4 pCi/L)
|
EPA
|
Recommended threshold for remediation in homes and schools; fix if levels are 4 picocuries per liter (pCi/L) or higher, with consideration for 2-4 pCi/L. No safe level exists, but this guides hazard prevention.
|
|
2
|
ANSI/AARST MAH-2019: Protocol for Conducting Measurements of Radon and Radon Decay Products in Homes
|
AARST/ANSI
|
Standard protocol for accurate radon testing in homes, including device placement, duration (short-term 2-90 days; long-term >90 days), and quality assurance to detect entry points.
|
|
3
|
ANSI/AARST SGM-SF-2023: Soil Gas Mitigation Standards for Existing Single-Family Homes
|
AARST/ANSI
|
Specifies minimum requirements for active soil depressurization systems to prevent radon entry in existing homes, including fan installation and sealing cracks.
|
|
4
|
ANSI/AARST SGM-MFLB-2023: Soil Gas Mitigation Standards for Existing Multifamily, School, Commercial, and Mixed-Use Buildings
|
AARST/ANSI
|
Guidelines for mitigating radon and soil gases in larger buildings via sub-slab depressurization, harmonized with single-family standards for broad prevention.
|
|
5
|
ANSI/AARST RRNC-2018: Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings
|
AARST/ANSI
|
Protocols for incorporating radon-resistant features (e.g., vapor barriers, vent pipes) during new home construction to prevent future hazards.
|
|
6
|
ASTM E2121-13: Standard Practice for Installing Radon Mitigation Systems in Existing Low-Rise Residential Buildings
|
ASTM International
|
Step-by-step installation standards for mitigation systems, emphasizing diagnostics, sealing, and post-mitigation testing to ensure effective prevention.
|
|
7
|
ANSI/AARST MAMF-2019: Protocol for Conducting Measurements in Multifamily Buildings
|
AARST/ANSI
|
Measurement guidelines for shared structures (e.g., apartments), focusing on sampling multiple units to detect and prevent occupant exposure.
|
|
8
|
EPA 625-R-92-016: Radon Prevention in the Design and Construction of Schools and Other Large Buildings
|
EPA
|
Technical manual for radon-resistant new construction in schools and large facilities, including site evaluation and venting to avoid entry pathways.
|
|
9
|
ANSI/AARST CCAH-2018: Reducing Radon in New Construction of 1 & 2 Family Dwellings & Townhouses
|
AARST/ANSI
|
Construction standards for rough-in radon controls (e.g., passive vents) in new homes, promoting proactive hazard prevention.
|
|
10
|
ASTM E1465-08: Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings
|
ASTM International
|
Options for radon barriers and drainage in new builds, integrated into model building codes to prevent soil gas intrusion.
|
These standards are voluntary consensus-based and adopted by states, HUD, and proficiency programs like NRSB. For full texts, visit epa.gov/radon or standards.aarst.org. Testing remains the first step—EPA urges all homes below the third floor be tested.
