Why use a Radon Barrier?
Naturally occurring radioactive radon gas is a breakdown product of radioactive uranium in the Earth’s crust. It is a known carcinogen and poses a chronic toxicity hazard to man. Radon is responsible for some avoidable 2,500 deaths a year from lung cancer in the UK. Geological studies and maps can only provide a rough guide to heavy pockets of the gas and never an accurate figure on the radon level in any one specific home or workplace. Because radon enters a building from the ground on which it is built, the most effective method of reducing indoor levels, is by preventing it entering the building in the first place. Recently published research indicates that a significant health risk exists at levels of radon lower than the current action level and the need for effective and improved protection is increasingly important. What is a Radon Barrier? This is a fully sealed very low gas permeability barrier (sometimes referred to as a membrane) placed over the entire footprint of the build
