What is Radon?


Radon is an odourless, colourless and invisible radioactive gas caused by the natural breakdown of radioactive material in soil and rock. You can't see, taste or smell radon, so the only way to know whether your property is affected, is to test for it. More...


Does it affect me?


Radon is present throughout the UK with some parts of the country being classified as Radon Affected Areas but even if your property is not within an RAA, it could still experience high radon levels. Testing is advised as prolonged exposure to increased radon has been linked to an increased likelihood of developing lung cancer. More...


Revised Health Protection Agency Advice on Radon

The Health Protection Agency recently revised their advice regarding radon exposure and created two new benchmarks: The Radon Target Level and the Radon Action Level. Previously, homeowners had just one radon level to consider when testing which was ensuring that their home had a radon level of no more than 200 Bq/m3. This advice has now been revised where the 200 Bq/m3 level is now regarded at the Radon Action Level.

In other words, if your home has an average radon level of 200 Bq/m3 or above, then you are strongly advised to take action to reduce this to the new Radon Target Level of no more than 100 Bq/m3.

These radon levels are much more in line with the advisory levels in the US and it is expected that these levels will be adopted formally by the EU at some point in the future. Radon Action and Target Levels in the workplace may be similarly revised downwards from the maximum level of 400 Bq/m3, to an Action Level of 300 Bq/m3 and a Target Level of 200 Bq/m3.
