&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;BRE (Building Research Establishment) is an independent, research-based consultancy, testing and training organisation, operating in the built environment and associated industries.&lt;br /&gt;
&lt;br /&gt;
[https://www.brebookshop.com/details.jsp?id=327328 Radon solutions in older homes (GR 38)] was written by Chris Scivyer and published by BRE on 2 April 2014.&lt;br /&gt;
&lt;br /&gt;
Radon is a natural, colourless, odourless, radioactive gas formed by the radioactive decay of small amounts of uranium that occur naturally in all rocks and soils. It can move through cracks and fissures in the subsoil and eventually to the atmosphere. Most of this radon will disperse harmlessly, but some will collect in spaces under or within buildings.&lt;br /&gt;
&lt;br /&gt;
For most UK residents, radon accounts for half the annual radiation they receive. Exposure to particularly high levels of radon may increase the risk of developing lung cancer. While it is recognised that the air inside every building contains radon, some buildings in certain areas of the UK might have unacceptably high concentrations unless precautions are taken. South-west England is of principal concern, but high concentrations of radon are also found in many other areas.&lt;br /&gt;
&lt;br /&gt;
This 8-page Good Repair Guide provides guidance for builders and homeowners carrying out works to reduce indoor radon levels in older homes. It describes different features found in older properties and explains how commonly-used radon remedial measures can be tailored to suit older buildings, including listed buildings or those located within conservation areas.&lt;br /&gt;
