As it’s a natural gas, radon is present throughout the UK with some areas more at risk of experiencing higher emissions than others. Part of the conveyancing searches will include discovering whether the property is situated within or near a raised radon area. Although odourless and colourless, high levels of radon gas can lead to health issues.
When looking at the UK Radon Map, you can see that the centre of St Albans does not appear to have high levels of radon gas - in fact, it has a maximum radon potential of less than 1%. However, the further west you travel, the higher the emissions begin to rise. Locations closer to Hemel Hempstead have a maximum radon potential of 1-3%. Although this is higher than some areas in St Albans, they are still fairly average readings.
Average levels of radon gas are usually no cause for concern. However, higher levels can affect your health over long periods of time and can even increase the risk of lung cancer. Once the searches have been completed, your conveyancer should be able to inform you of any threat present.
