Radon Monitoring of School Grounds

Radon Monitoring in Bristol

, , ,
Large parts of Bristol and the surrounding area are in High Risk zones for radon levels. Radon Monitoring and detection is an essential assessment required in risk areas throughout the UK. Earth Environmental & Geotechnical recently worked with a School in Bristol using MARKUS 10 instruments that allows for in-situ measurement of radon gas in soils. The Markus 10 can provide a clear understanding of the radon levels in the soil of your School site and can quickly allow for an informed decision whether the site requires radon mitigation measures.
