Radon gas is an invisible threat beneath our feet. Naturally released from the ground, this colourless and odourless radioactive gas can enter homes and buildings without any warning signs. Many families across Wales are unaware that they may be exposed to dangerous levels of radon every day. Long-term exposure significantly increases the risk of lung cancer, making radon one of the most serious environmental health hazards in the UK. Don't leave your family's health to chance, understanding your radon risk is the first step towards protecting your home and loved ones.
