Floor type: Solid Floor
To reduce radon with a radon sump, a passive sump system provides a simple means of allowing radon to escape from a cavity under a solid floor.
No fan is fitted in the system to extract radon. The difference in temperature between the bottom and top of the outlet pipe allows air movement out of the building.
Whilst passive sump systems can sometimes work, they generally have a limited impact on radon levels, in comparison to active systems (those that use a fan); so be prepared to add a fan to the system if it does not work very well.
Radon sump system performance
This document aims to determine if there are a set of tests and tools that are useful to assure installers andc ustomers that a radon system is performing to a reasonable standard, or whether another parameter is the causeof poor radon reduction post-system fitment.
