Full Description 1. These unobtrusive built-in soil depressurization options are installed with a pipe route appropriate for their intended initial mode of operation, that is, fan-powered or passive. The radon fan should be installed after 1 an initial radon test result reveals unacceptable radon concentrations and therefore a need for an operating radon fan, or 2 the owner has specified an operating radon fan, as well as acceptable radon test results before occupancy.

When the radon test results for a building with an operating passive system are not acceptable, that system should be converted to fan-powered operation. Radon systems with fan-powered type pipe routes allow the greatest architectural freedom for vent stack routing and fan location. The U. Congress in the Indoor Radon Abatement Act, is to reduce indoor radon as close to the levels of outside air as is practicable. The radon concentration in outside air is assumed to be 0. The goal of this practice is to make available new residential buildings with indoor radon concentrations below 2.

This practice also can be used as a reference for the federal, state, and local health officials and radiation protection agencies. Radon reduction for existing low rise residential buildings is covered by Practice E , or by state and local building codes and radiation protection regulations.

Historically, far more fan-powered soil depressurization radon reduction systems have been successfully installed and operated than all other radon reduction methods combined. These methods are not the only methods for reducing indoor radon concentrations The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Congress in the Indoor Radon Abatement Act, is to reduce indoor radon as close to a levels of outside air as is practicable. Radon systems with fan-powered type pipe routes allow the greatest architectural freedom for vent stack routing and fan location. Standards and protocols for conducting radon measurement and mitigation activities have been available since the early s, and were developed in several ways: National Radon Program Services. Radon is a colorless, odorless, tasteless, and chemically inert radioactive gas.

Radon Mitigation Standards for Schools and Large Buildings RMS-LB 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. Congress in the Indoor Radon Abatement Act, is to reduce indoor radon as close to the levels of outside air as is practicable.
