Home » Gases » Radon

Radon is a colourless, odourless radioactive gas that naturally occurs due to the radioactive decay of small amounts of uranium found in rocks and soils.

Radon is the second largest cause of lung cancer in the UK (after smoking), around 1100 deaths per year are attributed to radon related lung cancer.

Reducing the ingress of radon to below 200 becquerels is the aim when installing a radon protection system.

A radon sump, ventilation and a radon membrane make up the most common passive protection system, this is known as basic protection.

For areas or properties with very high radon levels an active system can effectively reduce the levels by mechanically pumping the radon from the sump out into the atmosphere. An active system also comprises of a sump and radon membrane, however there is an electrically operated pump connected to the sump and ventilation system.
