Radon Reduction Methods

A radon sump system is the most effective reduction method which has been known to reduce radon levels over 2000 bq/m³.   This system is fitted externally,   a small void will be created under the floor level.   A radon fan will be attached to draw the radon from under the property and dispersed into the atmosphere,  thus reducing the radon levels inside the home.    

For houses with a suspended floor  additional air bricks can installed in walls just above ground level.  This option is only viable if the readings slightly above the action level.   If this does not reduce the radon levels within the home alternative work will be required.

A Positive pressurisation system  is suitable for radon levels below 500 Bq/m³.   A loft mounted  system which is  designed to change the air pressure in your house by blowing air in from the loft (heated systems are available to preheat air before it passes into the home) thus diluting the radon within the home.  The vent is usually located within the landing area of a domestic property.   Advantages of this system is  its  economical to run & also reduces condensation.
