Book Description

The aim of this guide is to give practical advice and guidance on providing radon protection to new domestic extensions and conservatories with concrete floors and to explain why it is necessary. The Guide will also help house owners and builders in radon-affected areas to determine whether protection is needed for a new extension or conservatory and the level of protection that is required. Two further Good Building Guides will cover radon-protective measures for new dwellings and larger buildings (eg workplaces).
