Page 5: Introdcution
Introdcution The RADONTEC ALPHAEX was developed for the underfloor extraction of radon gas. With a drainage underneath the foundation, radon-containing soil air is extracted over a wide area and conducted outside by negative pressure. With a so- called radon well in or near the house, the radon-containing soil air is extracted selectively and thus kept away from the walls of the house that are in contact with the soil. - Page 6 Application example 1: Point radon extraction with discharge at floor level.
