Case Study

Eugene Monahan of All Clear Radon Ltd together with Waterford County Council.

Eugene Monahan, principal of All Clear Radon, is an engineer with 30 years engineering experience in Manufacturing, Construction and Radon protection. He has been full time involved in radon testing, radon protection and radon mitigation since 2000 and has undertaken radon projects for clients including The Department of Defence, Enterprise Ireland, The OPW, The HSE, The Greek Atomic Energy Commission and many other public and private bodies.

Eugene stated – “I have used the Flettner ventilator on many occasions to reduce radon levels in buildings. The benefit of the Flettner ventilator is that it does not require an electrical connection and runs on wind power alone. It is ideal for reducing radon levels in buildings with moderately elevated levels of radon. Our case study illustrates that the Flettner works best in buildings with existing radon barriers. Radon barriers are the most common form of protection against radon in new buildings but they are easily punctured and usually leak some radon into the building. The Flettner ventilator works by extracting the radon from beneath the radon barrier before it gets a chance to enter the building. It is proven to work well in reducing radon levels in these cases. In the above case study radon levels were reduced by 85% on average in building with existing radon barriers.”

“A simple and cost effective solution to low level radon problems.”
