Radon Gas Explained
Radon is a gas. The gas is produced when uranium which is found in rocks, the soil and water, is naturally broken down, it sediments, producing radium. Once radium decays it produces radon, a radioactive gas.
Why Is It A Risk To Health?
Although radon gas is initially harmless, once it enters our homes, work places and buildings the radon gas starts to decay, and forms solid particles. These particles can build up and, if not able to escape, can enter our lungs simply from breathing in the air. This has a huge impact upon health as when the particles hit the lungs they decay even further. The result of the reaction causes dangerous radiation to enter the lungs.
The National Radiological Protection Board (NRPB) reports health studies from around the world that have linked the increased risk of lung cancer with exposure to Radon.
How To Measure Radon Gas
A radon measurement is easy to complete. UK Radon will post you two detectors to place in your home: one in the living area and one in an occupied bedroom. After three months you post the detectors back in the pre-paid envelope provided. UK Radon analyse the detectors and post the results to you: the cost is £49.80 inc. VAT.
You can order your home measuring pack at a cost of £49.80 from the UK Radon – Public Health England
If your result is at or above the UK Action Level of 200 Bq m-3. . You will need to act.
Where Is Radon Gas Found?
Pockets of radon gas can be found in most places in the UK. As a result, thousands of homes suffer from radon penetration.
There are a higher percentage of homes that suffer from radon penetration in the East Midlands and the South West (Gloucestershire) The radon gas travels up and escapes through the rock into the atmosphere, and into nearby homes and properties. However, not all granitic regions are at risk.
How is Radon gas detected – what are the warning signs?
That’s just it, there are no visual or sensual signs. If suspected, the area can be inspected. Over a 3-month period detectors are used to measure radon gas. The Health Protection Agency’s UK Action Level for Radon in Homes is at or above 200Bq m-3. (measured in Becquerel’s per cubic metre).

How To Reduce Radon Gas?
Plastic membranes can be laid during the original construction of a property to prevent radon gas, which is a common-sense solution. However, membrane can tear and wear out over time, and not all properties may have been fitted with a membrane during construction. The next practical solution is to install what we call a Positive Input Ventilation System (PIV).
What are PIV’s and how can they help?
Positive Input Ventilation Systems are effective solutions that can significantly reduce levels of radon gas in your home. The units work by pumping filtered fresh air through the property. The pressure of the fresh filtered air being pumped through the property then pushes the radon gas out of your home.
PIV’s are highly energy efficient. They reduce your energy bills and provide a complete all year-round ventilation system. A pollution-free, less costly home!
