Radon: The Hidden Risk You May Not Know About

Radon is a naturally occurring gas formed from uranium found in rocks and soil. It is present everywhere, but levels outdoors are usually very low. Indoors, however, radon can sometimes build up and become a potential health risk.

Radon maps are often used to show where higher levels are more likely. The darker the colour on these maps, the greater the chance of higher radon levels in buildings. However, even in darker areas, not every home will have high levels.

Understanding Radon Levels

Radon is measured in becquerels per cubic metre of air, known as Bq m-3.

• The average radon level in UK homes is around 20 Bq m-3

• Levels below 100 Bq m-3 are considered low risk and generally not a cause for concern

• Health risks increase as radon levels rise above this level

For most homes, the overall risk remains small, but testing can provide peace of mind, particularly in higher risk areas.

Takeaway

Radon is common and usually harmless at low levels, but it is worth checking your area. A simple test can help ensure your home remains safe.
