Radon Gas Properties

What is Radon Gas?

Radon Gas is a naturally occurring radioactive gas that was first discovered in 1900, but the health risks of exposure to the gas were only discovered in 1984. Being odourless and colourless it is undetectable by human senses alone, this is why Radon gas has been dubbed ‘ the silent Killer’. Radon is caused by tiny particles of uranium present in all rocks, bricks, soils and concrete, and as such, there is the potential for the accumulation of radon gas in confined areas such as basement or attics. In general the amounts of radon gas are small and pose no health risks.

However, higher concentrates of the gas can significantly increase the risk of lung cancer. Radon gas is attributed to an estimated 1000 to 2000 deaths each year, due to unknown exposure, but radon gas is relatively easy to remove if found present in your home.

Is your home at risk?

Find your location on the HPA’s Radon Maps. If your home or property is in one of these “high risk” affected areas you should consider the risk of radon gas contamination. We would then recommend that you consider conducting a very simple radon test with a radon test kit which can be purchased from us at a cost of £38.00. If unacceptable levels of Radon Gas are found then we would advise that you contact us on 0845 658 7777.

MacLennan can design and install Radon gas and ground gas systems to deal with Methane, C02. The systems can be part of a combined waterproofing system or a standalone system. Some contractors will claim that it is mandatory yo install a gas proof system ( at additional cost ) this is not the case. MacLennan or your engineer can advise if gas remediation is necessary

‘Long term exposure can produce symptoms such as shortness of breath, chest pain, and other respiratory distress’.

Advice from DEFRA states that there are 5 ways to reduce Radon Gas levels in a property dependent on the type of property and the levels of Radon Gas that are present.

  • 1. Install a radon sump system
  • 2. Improve ventilation under suspended timber floors
  • 3. Use a positive pressure ventilation system
  • 4. Seal cracks and gaps in solid concrete floors
  • 5. Change the way the property is ventilated

Radon Maps

Radon Gas concentrations are significantly influenced by the local geological formations, therefore some areas of the UK can be at more risk than others. Regional maps have been produced by HPA who have studied Radon gas in The UK. If your home is in one of these regions it does not follow that you will be affected by Radon Gas. Factors including construction and ventilation of your home will determine if you have a radon gas problem. The map below is a guide to Radon Gas in your area.
