Where radon occurs
Radon is a naturally-occurring radioactive gas produced by uranium decaying underground. It seeps into buildings through floors, walls in contact with soil, and through water or gas supplies. When inhaled, radon atoms decaying in our lungs can cause damage to cells and cause lung cancer.
It’s associated with geological types like granite and shale, and the probability of finding high radon levels has been mapped for the UK in the ‘Indicative Radon Atlas.’ Although detailed, it only gives an indication – you have to test to be sure.

With the ACUMEN project now in its final month, the Environment Agency and CIWM will be hosting a webinar. The webinar will focus on some of the headline facts and figures from our practical field scale demonstrations of ways to manage the gas at closed landfill sites. Additionally, the webinar will be an opportunity for us to provide an overview of the tools and reports that the ACUMEN Project Team have produced to help people tasked with managing closed landfills. More information about the project is included in our latest Project Update which is available here
To reserve your place on the webinar please use the link below. Please note that places are limited.

Everyone agrees that Britain needs new homes, and quickly. Targets at both local and national levels increasingly focus on the redevelopment of brownfield sites; with the dream of transforming derelict space into thriving communities. Of course, the simple message sold to voters doesn’t encompass the difficulty of clearing and converting a former industrial unit into flats, or building on old landfill. Ground-gas can be a danger in any development but, as the focus switches to brownfield, developers are increasingly being expected to officially validate that effective ground-gas measures are ensuring the safety of future site users.

Ground Gas Solutions Limited (GGS) are delighted to be involved in a new course on the environmental monitoring of water and methane for the onshore oil and gas industry. This new course is delivered by Envireau Knowledge in partnership with Envireau Water, Peter Dumble Hydrogeology, GeoWater, In-Situ and GGS and will take place on the 25th August 2015 at the University of Birmingham.
The course is aimed at a relatively high level, to demonstrate to onshore oil and gas operators why monitoring is required and what the key issues are for their industry. It is directed at operating companies and those responsible

BS 8485:2015 – Code of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings
BSI have just published the long awaited revision to the 2007 document.
Toxic, asphyxiating or explosive gases can leak from the ground and accumulate in buildings, posing health risks. The standard describes how to characterize sites and prevent the entry of carbon dioxide and methane into new buildings. This revision has now been substantially expanded and revised to reflect changes in good practice and reference other standards since the last edition was published.
The revised document provides the highest level of guidance in the UK on this subject and while keeping to the ethos and spirit of the simple point scoring system of design, it is much expanded to provide clearer guidance on:
- interpreting gas monitoring data
- selecting membranes
- changes to gas protection scores
- worked examples
- user flow charts
And in addition to methane and carbon dioxide it also provides recommendations through new annexes on radon and volatile organic compounds (VOCs).
Hazardous gases may be present in the ground naturally, or from contamination, mine working or buried wastes. Two of the major risks are methane, which is flammable (explosive in confined spaces) and an asphyxiant, and carbon dioxide, which is both toxic and an asphyxiant.
The standard provides guidance on site investigation, determining ground gas parameters and using those to identify protective design solutions. It is not prescriptive – recognising that there are many factors involved, that a range of design solutions are available for different situations, and that professional judgement is often needed. Emphasis is placed on justification and recording of risk assessments and design decisions so that the whole process will be transparent for consultants, developers and regulators.
Ground-Gas Solutions Comment
Ground Gas Solutions works hard to promote best practice in the contaminated land sector and believes that this document provides a further step forward to improved ground-gas protection for the UK construction industry.
