CCAH-2020

CCAH Introduction Reducing Radon in New Construction of One & Two Family Dwellings and Townhouses ANSI/AARST CCAH 2020 introduction Scope Summary This standard provides minimum requirements for the rough-In of radon control system components in new dwelling units under construction. CCAH also includes minimum requirements for verifying if radon concentrations are below the national action level and, if required, activation of radon control systems. This standard is harmonized to compliment the standard designated as ANSI/AARST RRNC, which replicates construction activities for rough-In components only. Significance of Use This standard was developed to respond to the threat of cancer caused by radon gas in homes. Radon is the leading cause of lung cancer among nonsmokers and the second leading cause of lung cancer in the general population. 1 Most people receive their greatest exposure to radon in their homes. Radon in U.S. homes causes approximately 21,000 lung cancer deaths each year. 2 Be it at home, work or school, an individual’s exposure to radon gas combines over time to increase the risk of preventable lung cancer. Designation of this standard: CCAH As used for catalogue identification, “CCAH” stands for Construction Code Applicable to Homes. The Consensus Process and Continuous Maintenance The consensus process developed for the AARST Consortium on National Radon Standards and as accredited to meet essential requirements for American National Standards by the American National Standards Institute (ANSI) has been applied throughout the process of approving this document. This standard is under continuous maintenance by the AARST Consortium on National Radon Standards a program has been established for regular publication of addenda or revisions, including procedures for timely consensus action on requests for change to any part of the standard. User Tools: User tools are posted online ( https://standards.aarst.org/public-review/ ) as they become available such as interpretations and approved addenda updates across time.
