Radon is a colourless, odourless radioactive gas formed by the radioactive decay of small amounts of uranium that occur naturally in all rocks and soils. Every building contains radon, but the levels are usually very low. The chances of a higher level depend on the type of the ground and locality. Our structural engineers can review the national radon maps published by Public Health England, to assess the radon levels to your property. We can also advise on appropriate monitoring of radon levels and advise on suitable works to reduce the health risks associated with high radon levels.
