Radon Testing

Our Radon Team at Timberwise have been kept busy as a result of the increased awareness of Radon gas with property owners. In this post we take a look at Radon gas, how you can test for Radon gas as well as an example of how Radon levels can be reduced should your property be at risk of Radon gas.

Radon is a natural occurring radioactive gas that is generated through either the radioactive decay of uranium in minerals and rocks such as granite, or from radium luminised articles. Radon can seep into properties from the ground into cracks and gaps within the fabric of the building and if inhaled by occupants this may cause a health risk.

As Radon is a gas it can be measured, through the air activity concentration and is measured in Becquerel per cubic metre (Bq m-3). The current action level in the UK is 200 Becquerel per cubic meter and therefore anything above this level can be harmful and action needs to be taken.

Radon Fan Assisted Sump SystemA school that became aware of these issues contacted our Radon specialists for help and advice on how to test for Radon, being concerned that the property may be in a high risk area. Our Radon team recommended carrying out a 3 month Radon test kit to the client which provides accurate results as the test kits have been potentially exposed to Radon for a longer period of time.

The test included 2 Radon detectors that needed to be installed in areas that were open and occupied for a majority of the time such as staff rooms, offices, class rooms etc. The detectors were than left for 3 months measuring the air activity concentration levels and then sent and tested within the lab for evidence of high Radon levels.

Following the Radon test, the results did in fact indicate high levels of Radon, particularly within the head teacher’s office and a joining staff room. A survey was then carried out within the property to determine the best solution for the Radon affected areas as the levels were so high. From the survey our Radon expert advised the best solution would be to recommend an installation of a fan assisted Radon sump.

The clients were happy for our Radon team to install the recommended sump as this would ‘suck’ air and Radon gas from the affected areas, and dispel the Radon gas at roof level to disperse harmlessly into the atmosphere, as shown in the picture to the left.

What should I do if I suspect I may be living in a Radon affected area?

Testing for Radon is a simple process. To identify Radon levels in your property you will need a Radon test kit – these can be purchased securely from our on-line shop. Choose from either a 3 month kit or, if you need to know results quicker, a 7 day kit. Kits cost £38 and include VAT, Delivery, testing and a report detailing the findings.
