What Are The Radon Health Effects?

Radon health effects are serious. First let's look at this gas. It is a naturally occurring gas that is odourless, tasteless and colourless. It is naturally found in the earth as it is a by product of radioactive uranium decaying . It leaks from the ground into your home through cracks or holes in the foundation, walls, floor (brick and concrete) and drains, especially a problem for homes with cellars or any rooms below ground level.

Exterior levels of radon are much lower than interior levels – caused by poor ventilation. Radon is found in both newly built homes and longer standing properties. Concentration levels are also affected by the type of earth your home is built on. Land which has large quantities of granite, phosphate and shale hold higher levels of radon. Waste landfill sites also hold high levels of radon which can cause them to be explosive when exposed to other waste emissions.

The concentration of radon in the air in your home will differ depending on the time of day and the season. Highest levels occur during the night and in the winter months. Rooms below ground and the ground floor will typically hold higher levels as they are closer to the source.

Health effects

Radon is a dangerous air pollutant as it holds high levels of carcinogens which primarily cause lung cancer. This gas can build up in your home or any building over time, and as you cannot see it, smell it, taste it or detect it – it may be negatively affecting your health without knowing. Radon exposure is through inhalation and the radioactive elements attach themselves to your lungs, meaning they do not leave your body when you breathe out. Sypmtoms are not experienced immediately on exposure to Radon. However it is known to cause lung cancer which has its own symptoms. If you smoke and are exposed to concentrated levels of radon, then your chances of developing lung cancer can increase by up to 10 times. As with all symptoms and illnesses please consult a doctor

What can you do?

• Do it yourself radon testing kits are available in most DIY shops.
• Constant, fresh and natural ventilation helps disperse indoor air pollutants and will lower levels of radon. It is very important to prevent your home becoming a ‘tight building’ especially during winter time.
• Get your foundations, walls and flooring checked for any cracks or holes and have them sealed.
• Avoid using your cellar or basement as a main living area.
• Contact your local authority for a home inspection where radon levels are measured.
