NRSB Recognized Radon Standards

NRSB Recognized Radon Standards
The NRSB recognizes all ANSI/AARST radon standards as an alternative to the previously recognized radon standards established by the EPA and ASTM. An NRSB certificate holder must follow the standards recognized by the state in which they are conducting business and their QA plan must list the standards that are being followed.
 

Below is a list of the current ANSI/AARST Standards

  1. ANSI/AARST MW-RN-2020 – Protocol for the Collection, Transfer and Measurement of Radon in Water
  2. ANSI/AARST SGM-SF-2017 with 12/2020 REVISIONS – Soil Gas Mitigation Standards for Existing Homes
  3. ANSI/AARST MAMF-2017 with 1/2021 REVISIONS – Protocol for Conducting Measurements of Radon and Radon Decay Products in Multifamily Buildings
  4. ANSI/AARST RMS-MF-2018 with 12/2020 REVISIONS Р Radon Mitigation Standards for Multifamily Buildings
  5. ANSI/AARST MALB-2014 with 1/2021 REVISIONS – Protocol for Conducting Measurements of Radon and Radon Decay Products In Schools and Large Buildings
  6. ANSI/AARST RMS-LB-2018 with 12/2020 REVISIONS – Radon Mitigation Standards for Schools and Large Buildings
  7. ANSI/AARST RRNC-2020 – Rough-In Of Radon Control Components In New Construction Of 1 & 2 Family Dwellings And Townhouses
  8. ANSI/AARST CCAH-2020 – Reducing Radon In New Construction Of One & Two Family Dwellings And Townhouses
  9. ANSI/AARST CC-1000-2018 – Soil Gas Control Systems in New Construction of Buildings

    4. Testing Protocols.
    a. Radon testing must follow the protocols set by the American Association of Radon Scientists and Technologists, Protocol for Conducting Radon and Radon Decay Product Measurements in Multi-family Buildings (ANSI-AARST MAMF-2010, Section III (or similar section in the most recent addition), (available at http:www.aarst.org/bookstore.shtml).
    1. Exception: With reference to Section III.3.1 of ANSI-AARST MAMF-2010 (or similar section in the most recent edition). the minimum number of apartments to be tested shall be at least twenty-five percent of randomly selected ground level units.
    b. Threshold for unacceptability: 4.0 picocuries per liter (4.0 pCi/L) based on initial and any confirmatory testing, if performed.

    5. Resident Notification.
    a. Testing. Resident of all new applications for Multi-family MAP and TAP programs shall be performed of forthcoming testing in the manner described in ANSI-AARST MAMF-2010, Section II.B and Section III.2.2.1 (or similar sections in the most recent edition).
    b. Mitigation. Residents shall be informed both prior to and after mitigation activities. In the case of new construction, incoming residents shall be informed of radon mitigation activities.
