AARST: American Association of Radon Scientists and Technologists

AARST, the American Association of Radon Scientists and Technologists, is a nonprofit organization headquartered in Fletcher, North Carolina and founded in 1988. AARST has been creating national radon standards with ANSI approval since the early 2000s. AARST does work in Washington, D.C. on public policy, steadily gaining agreement there that radon is the second leading cause of lung cancer. The leadership of the organization is democratically elected by the members. Standards from AARST are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: StandardsSubscriptions@ansi.org or 1-212-642-4980 or Request Proposal Price.

ANSI/AARST MAMF-2017

Protocol for Conducting Measurements of Radon and Radon Decay Products in Multifamily Buildings

This standard of practice specifies procedures, minimum requirements and general guidance for measurement of radon and radon decay product concentrations in Multifamily buildings that have more than one attached dwelling. Provided with this document is an "Informational Introduction to Radon" and an "MAMF Companion Guidance" document that includes informational guidance for residence managers.


ANSI/AARST MALB-2014

Protocol for Conducting Measurements of Radon and Radon Decay Products In Schools and Large Buildings

This standard of practice specifies procedures, minimum requirements and general guidance for measurement of radon and radon decay product concentrations in schools and large buildings.  This document includes:  I.) Informational Introduction to Radon;  II.) Informational Guidance for Building Managers; and  III.) Protocol for Conducting Measurements of Radon and Radon Decay Products in Schools and Large Buildings.


ANSI/AARST SGM-SF-2017

Soil Gas Mitigation Standards for Existing Homes

This standard of practice specifies practices, minimum requirements and general guidance for reducing soil gas entry into existing homes in order to mitigate occupant exposures to certain hazardous soil gases, including radon gas, chemical vapors and other hazardous gases. This standard of practice addresses a wide range of mitigation methods and additionally provides guidance for health and safety, system design, system installation, and ongoing stewardship.  This standard of practice is applicable to residential structures to include: those not more than three stories above grade in height; those often classified as single-family structures; and those that contain not more than four attached dwelling units on a contiguous foundation.


ANSI/AARST CC-1000-2017

Soil Gas Control Systems in New Construction of Buildings

The provisions in this standard provide prescriptive minimum requirements for the construction of any building intended for human occupancy, except for 1 and 2 family dwellings, in order to reduce occupant exposure to radon and other hazardous soil gases.   This standard addresses construction of buildings that include, among others, the use of a building or structure, or a portion thereof for multifamily or congregate residential occupancies, educational occupancies and commercial occupancies.


ANSI/AARST MAH-2014

Protocol for Conducting Measurements of Radon and Radon Decay Products in Homes

This standard of practice specifies minimum requirements and general guidance for measuring radon concentrations in single-family residences. This standard applies to testing structures whether conducted for real estate or non-real-estate purposes.  The purpose of test protocols is to consistently produce, to the extent possible, reliable and repeatable radon measurements. Radon measurements are conducted to determine if radon mitigation is necessary in order to protect current and future occupants.


ANSI/AARST CC-1000-2018

Soil Gas Control Systems in New Construction of Buildings

This standard provides minimum requirements for the construction of any building intended for human occupancy, except for 1 and 2 family dwellings, in order to reduce occupant exposure to radon and other hazardous soil gases. It addresses buildings that i


ANSI/AARST RMS-LB-2014

Radon Mitigation Standards for Schools and Large Buildings

This standard of practice specifies minimum requirements and general guidance for mitigation of radon in existing schools and large buildings. The techniques addressed in this standard provide whole-building consideration yet also apply to portions of a building or individual occupied spaces.  This standard is intended to provide uniform standards that emphasize safety, system quality and effectiveness in the design and installation of mitigation systems for existing schools and large buildings.


ANSI/AARST RMS-MF-2014

Radon Mitigation Standards for Multifamily Buildings

This standard of practice specifies minimum requirements and general guidance for mitigation of radon in existing multifamily buildings. The techniques addressed in this standard provide whole-building consideration yet also apply to portions of a multifamily building or individual dwellings.  This standard is intended to provide uniform standards that emphasize safety, system quality and effectiveness in the design and installation of mitigation systems for existing multifamily buildings.


ANSI/AARST RMS-LB-2018

Radon Mitigation Standards for Schools and Large Buildings

This standard of practice specifies minimum requirements and general guidance for mitigation of radon and soil gas in existing schools and large buildings. The techniques addressed in this standard provide whole-building consideration yet also apply to portions of a building or individual occupied spaces.  Improvements to RMS-LB 2018 include harmonized provisions with ANSI/AARST standards RMS-MF (multifamily), SGM-SF (existing homes) and CC-1000 (new construction).


ANSI/AARST RMS-MF-2018

Radon Mitigation Standards for Multifamily Buildings

This standard of practice specifies minimum requirements and general guidance for mitigation of radon and soil gas in existing multifamily buildings. The techniques addressed in this standard provide whole-building consideration yet also apply to portions of a building or individual occupied spaces.  Improvements to RMS-MF 2018 include harmonized provisions with ANSI/AARST standards RMS-LB (schools and large buildings), SGM-SF (existing homes) and CC-1000 (new construction).
