Radon is a colourless and odourless radioactive gas. It is formed by the radioactive decay of small amounts of uranium that occurs naturally in all rocks and soils.
The problem occurs when the radioactive gas decays as it produces another radioactive element called Radon’s Daughters, which can attach themselves to dust particles in the air and, if inhaled, they will stick to the airways of the lung. According to the National Radiological Protection Board (NRPB), health studies have linked exposure to Radon to the increased risk of lung cancer.
Radon gas is particularly dangerous and exposure can damage the health of the occupants in a property where the gas is present. Radon emissions can enter your home from the ground. It is mainly found in areas with high levels of granite and other igneous rocks such. Radon penetration occurs in thousands of homes in the UK. However, it’s interesting to note that not all granitic regions are prone to high emissions of radon; if the rock lacks pores/cracks then the gas will have no way of migrating.
Radon emissions are measured in becquerels and the NRPB has advised the Government that a home with radon levels of 200 becquerels or more should be reduced to as low as reasonably possible.
The Government openly recommends proper ventilation in the home as a way to mitigate radon emissions. EnviroVent's range of whole house ventilation units are an effective option when it comes to reducing and controlling radon emission levels in the home to below 200 becquerels. Our Positive Input Ventilation (PIV) is a method of ventilation which forces the contaminated air out of the home by supplying fresh, filtered air into the property at a continuous rate. In addition to reducing Radon gas levels, PIV units also help to prevent condensation and mould problems occurring, creating a healthy indoor environment all year round.
