Radon Kernow provides consultancy and remediation homes and businesses affected by Radon in Cornwall.

Radon is a colourless, odourless radioactive gas that occurs naturally in rocks and soil. The radon level in the air we breathe is usually very low, but it can be found in higher concentrations inside buildings, where it can collect.

Radon occurs throughout the UK, but concentrations differ, depending on location. Cornwall is one of the areas in the UK where higher concentrations of radon are found more often. The Radon Kernow team, working with Cornish homeowners and residents, aim to reduce radon gas levels in Cornish properties to safer levels.

If you want to buy radon products, have radon issues in your workplace, or in other counties across the UK, or want more detailed technical information, please go to our companion website at UK Radon Ltd.
