Why does Ireland grapple with higher radon levels than other countries, and what does that mean for our homes?
We unravel these questions with James McGrath, an expert in indoor air quality and building ventilation from the University of Maynooth. Learn why granite-rich regions are particularly susceptible to radon infiltration and how historical and modern building practices influence indoor radon accumulation.
Discover practical strategies for tackling radon, from installing radon barriers to ventilation systems, and understand the challenges of retrofitting older structures.
James shares his expertise on effective remediation techniques such as sub-slab depressurization and discusses the critical balance needed in ventilation to manage radon risks. With insights into the importance of regular testing, this episode emphasizes the unpredictable nature of radon infiltration and the need for ongoing assessment.
We also explore the impact of energy retrofits on radon levels, highlighting the challenges of increasing a building's airtightness without compromising indoor air quality. James sheds light on current research and projects aimed at understanding radon fluxes and risk factors, stressing the importance of testing before and after retrofits.
Together, we address the psychological barriers to radon mitigation and the crucial need for awareness about this hidden yet significant health risk.
James is an assistant professor at the University of Maynooth. He coordinates the Certificate in Science Programme and lectures on the undergraduate physics modules within the Department of Experimental Physics.
He conducts fundamental and applied research in the remit of the indoor built environment, focusing on indoor aerosol dynamics, air quality and building ventilation.
I've known James for close to 10 years and have always followed his work with interest, not least his fascinating research over the last few years on Radon and, in particular, the impact of retrofit on Radon risk.
