Current Radon Standards of Practice

Copies of the following Radon Standards of Practice may be purchased from Association of Radon Scientist and Technologists book store Exit, or from the American National Standards Institute store Exit.

Image of Radon Mitigation Standards for Schools and Large Buildings

Radon Mitigation Standards for Schools and Large Buildings (RMS-LB 2018)
This new American National Standard addresses the complexities of properly mitigating radon in large and complicated building structures that require specialized techniques and quality assurance to address complicated building designs and specialized airflow.

Protocols for Measuring Radon and Radon Decay Products in School and Large Buildings

Protocols for Measuring Radon and Radon Decay Products in Schools and Large Buildings (MALB 2014)
This new American National Standard addresses the complexities of properly measuring radon in large and complicated building structures that require specialized techniques and quality control and assurance to address complicated building designs and specialized airflow.

Image of Protocols for Conducting Rand and Radon Decay Product Measurements in Multifamily Buildings

Protocol for Conducting Radon and Radon Decay Product Measurements in Multifamily Buildings (MAMF-2017).
This ANSI/AARST standard is for measuring radon levels in multifamily housing.

Image of Radon Mitigation Standards for Multifamily Buildings

Radon Mitigation Standards for Multifamily Buildings (RMS-MF 2018)
This new American National Standard addresses the complexities of properly mitigating multifamily dwelling over four units that require specialized techniques and quality assurance.

Protocols for Measuring Radon and Radon Decay Products in Homes

Protocols for Measuring Radon and Radon Decay Products in Homes (MAH 2014)
This American National Standard is the first complete consensus standard and is an update of the 1993 EPA Protocol on Radon and Radon Decay Measurement in Homes.

 Reducing Radon in New Construction

Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses (CCAH 2012)
To control for radon in the construction of new residential homes.

Image of Soil Gas Mitigation Standards for Existing Homes

Soil Gas Mitigation Standards for Existing Homes (SGM-SF 2017)
The newest standard and the only American National Standard on radon mitigation for single-family homes.It also addresses mitigation of chemical vapor intrusion and virtually all non-ASD mitigation methods.  

Image of Soil Gas Control Systems in New Construction of Buildings

Soil Gas Control Systems in New Construction of Buildings (CC-1000 2018)
This new standard addresses RRNC construction for virtually every building that is larger than a one- and two-family dwelling.

Image of Radon Measurement Device Requirements

Radon Measurement Device Requirements (MS-PC 2015)
Every step of measurement and QA relies on performance of devices. A comparative examination of Spikes, Dupes, Blanks, Performance Tests and Calibration.

*Federal participation in the development and use of voluntary consensus standards, and in conformity assessment activities is governed by the National Technology Transfer and Advancement Act (1995), and Circular A-119 (2016, 1998) issued by the Office of Management and Budget, Executive Office of the President. Since about 2012, EPA has been actively participating in the radon industry led ANSI/AARST voluntary consensus-based standards process. As a general principle, the Federal government’s reliance on privately developed voluntary consensus based standards is to be preferred over the Federal government developing such standards.

Older Radon Standards of Practice

ASTM’s Standard Practice for Installing Radon Mitigation Systems in Existing Low-Rise Residential Buildings

Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings Exit *
For information to control radon in new residential construction, see ASTM's Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings. 

Protocols for Radon and Radon Decay Product Measurements in Homes

Protocols for Radon and Radon Decay Product Measurements in Homes
(EPA 402-R-92-003, May 1993 *this is a corrected document number)
This document presents the U.S. EPA's technical guidance for measuring radon concentrations in residences. It contains protocols for measuring radon for the purpose of deciding on the need for remedial action, as presented in the 1992 A Citizen's Guide to Radon, and in the Home Buyer's and Seller's Guide to Radon.

Indoor Radon and Radon Decay Product Measurement Device Protocols

Indoor Radon and Radon Decay Product Measurement Device Protocols(EPA 402-R-92-004, July 1992)
This document provides information, recommendations, and technological guidance for anyone providing measurement services using 15 radon and radon decay product measurement methods. These protocols provide method-specific technological guidance that can be used as the basis for standard operating procedures.

 Technical Guidance (Third Edition) for Active Soil Depressurization

Radon Reduction Techniques for Existing Detached Houses: Technical Guidance (Third Edition) for Active Soil Depressurization Systems (TXT) (EPA 625/R-93-011, October 1993)
This technical guidance document has been prepared to serve as a comprehensive aid in the detailed selection, design, installation and operation of indoor radon reduction measures for existing houses based on active soil depressurization techniques. It is intended for use by radon mitigation contractors, building contractors, concerned homeowners, state and local officials and other interested persons. Office of Research and Development.

Radon Measurement in Schools

Radon Measurement in Schools (Revised Edition - Second Printing)
This report was prepared to provide school administrators and facilities managers with instructions on how to test for the presence of radon. The findings from EPA's comprehensive studies of radon measurements in schools were incorporated into these recommendations. This report superseded Radon Measurements in Schools - An Interim Report.

Model Standards and Techniques for Control of Radon in New Residential Buildings

Model Standards and Techniques for Control of Radon in New Residential Buildings(EPA 402-R-94-009, March 1994)
This document is intended to serve as a model for use by the Model Code Organizations, States and other jurisdictions as they develop and adopt building codes, appendices to codes, or standards specifically applicable to their unique local or regional radon control requirements.

Standard Practice for Radon Mitigation Systems in Existing Low-Rise Residential Buildings

Standard Practice for Radon Mitigation Systems in Existing Low-Rise Residential Buildings*
To mitigate radon in homes, see ASTM E2121-12 Standard Practice for Radon Mitigation Systems in Existing Low-Rise Residential Buildings.
