The radioactive gas Radon is a hazard in many homes and workplaces. Breathing in radon is the second largest cause of lung cancer in the UK resulting in up to 2. Naturally occurring, it is particularly prevalent in granite and limestone areas but not exclusively so. Radon levels vary not only between different parts of the country but even between neighbouring buildings. You should make provision for an active protection measure by installing radon sump and. What you do if you need to activate the radon soil gas barrier protection system. Monarflex Radon Control Systems CI/SfB (13.9) June 2007. Radon Accessories Monarflex Top Hats. Free Cavity tray detailing service is available from Icopal technical services. Breathing in radon is the second largest cause of lung cancer in the UK resulting in up to 2. Naturally occurring, it is particularly prevalent in granite and limestone areas but not exclusively so. Radon levels vary not only between different parts of the country but even between neighbouring buildings. However radon that enters enclosed spaces, such as buildings, can reach relatively high concentrations in some circumstances. Reducing Radon In Your Home. The EPA Consumer's Guide to Radon Reduction is available for download. Mitigation Facts and FAQs. There are advantages to installing a system when building a house. Use this radon ventilation fan to ventilate radon out of your crawl space. Side Wall Radon Mitigation Fan; Radon Mitigation System. 1 Radon: Frequently Asked Questions. What is radon and why is it a concern? Radon is a radioactive gas that comes from the breakdown of naturally occurring uranium in soil and rock. It is invisible, odorless and tasteless. Radon from the ground is drawn into buildings through cracks and gaps because the atmospheric pressure inside the building is usually slightly lower than the pressure in the underlying soil. The production of landfill gas is a recent problem as the organic waste content of landfills has increased since the introduction of the first Clean Air Act in 1. Before this, most domestic waste was burnt and so landfill sites contained a high proportion of ash, a material that does not generate large quantities of landfill gas. It should also be noted that it is not just domestic waste landfills that produce gases, industrial and demolition waste landfills may also have the potential to generate large quantities of landfill gas. There are many hundreds of types of trace gases but most do not usually represent a health hazard following normal atmospheric dilution. Ground gas can be formed by natural or man- made means. The following are common sources and their typical components. Peat bogs and mosslands (CH4, CO2)Uranium bearing rocks such as granites (Radon)Carbonate rocks such as limestone and chalk (CO2)Organic rich rocks such as coal measures (CH4, CO2, H2. S)River and lake sediments (CH4, CO2, H2. S)Made ground (ground that has been formed by the activities of man and can consist of natural or man made materials) (CH4, CO2, H2. S, VOCs and any other gas)Farmland. Sewers. Precautions need to be taken for Methane as it may give rise to a variety of hazards if it migrates to, and accumulates in, a property or confined spaces. If generated in sufficient quantity the gas may form an explosive mixture with air. It can also act as an asphyxiant and in particular circumstances it may be toxic. For more detailed information please refer to BRE Guidance 3. Guide to Remedial Measures in Existing Dwellings (available from BRE book shop - see useful links below) which identifies following methods of reducing the amount of radon entering the basement. Sealing floors and walls. Increasing under- floor ventilation. Improving ventilation to the basement area. Installing a Radon Sump. Introducing positive pressure ventilation to the property Improving ventilation to the property. In areas shown as light grey on the maps, then an appropriately installed waterproofing system would generally suffice. However in areas with high radon levels, then the installation of a Platon cavity drain system along with a Triton Radon Sump and/or Positive Pressure Fan would be appropriate. It is always recommended to monitor the basement Radon levels after installation to ensure the installed measures are more than adequate. Appropriate measures should also be taken to limit their effect on the basement and the remainder of the property. Please refer to The Building Regulations 2. Part C - Approved Document Basements for dwellings, published by the Basement Information Centre. BS 8. 48. 5: 2. 01. It is not prescriptive – recognising that there are many factors involved, that a range of design solutions are available for different situations, and that professional judgement is often needed. Emphasis is placed on justification and recording of risk assessments and design decisions. It includes clearer guidance on interpreting gas monitoring data and selecting membranes, changes to gas protection scores, and many new features including worked examples for a range of conditions and building types. Please note that the standard applies to new buildings only, and is focused on carbon dioxide and methane. Purchase BS 8. 48. Triton Eco Roof Fan.
