Protecting Buildings On Radon Affected Land

Radon is a naturally occurring, colourless and odourless radioactive gas. It was discovered in 1900 by the German physicist Friedrich Ernst Dorn, who was studying the radioactive decay of Radium, itself only discovered by Marie Curie two years earlier. This work was expanded by the Nobel prize winning Scottish chemist Sir William Ramsey, who identified Radon as the heaviest gaseous element, 9 times heavier than air.

In ground gas terms, most radon is produced by the radioactive decay of trace amounts of uranium found in certain types of soil and rock, and as such the levels of gas present are determined by the underlying geology of the site as opposed to any historical usage or pollution.

This type of geology is most common in areas with granite bedrock such as south west England, the Peak District, north east Scotland and Northamptonshire. Aberdeen in Scotland, being known as the... Continue Reading.

Step by Step: How to Provide Ground Gas Protection

Providing Ground Gas Protection

Since 2008, the number of new households in the UK has continued to exceed the number of new houses actually built. Over the last few years, the UK government has dedicated more of its resources to reversing this trend. The 2017 Autumn Budget, for example, committed £15.3 billion of new financial support to house building over the next five years, and included funds for new infrastructure, land buyouts and the creation of five new ‘garden’ towns. The government has also set a goal of constructing 300,000 new homes per year by the mid-2020s, a rate of house building not seen in the UK for nearly 50 years.

The development of greenfield sites alone is not the answer; the remediation of suitable brownfield sites must play a role in helping UK builders achieve the government’s ambitious targets for new housing provision. To this end, a number of initiatives have been launched to help streamline the brownfield remediation process. An understanding of common soil contaminants, the process of brownfield site classification, and the components that make up a comprehensive ground gas protection system is essential for new construction to be built safely over brownfield sites...
