Radon Monitoring and Detection

Radon Monitoring and detection is an essential assessment required in risk areas throughout the UK. Earth Environmental & Geotechnical have invested in a MARKUS 10 instrument that allows for in-situ measurement of radon gas in soils.

If you are planning a new residential or commercial development the Markus 10 can provide a clear understanding of the radon levels in the soil of your development site and can quickly allow for an informed decision whether the development requires radon mitigation measures.

The Radon Atlas shows the bands of radon risk in each 1 kilometre grid square of England and Wales. This is only a coarse gridded assessment of radon potential, defined as the estimated percentage of homes in an area above the radon action Level. The risk is indicative not definitive, and the atlas shows the whole 1km grid square according to the highest radon potential.

The advantage of the Markus 10 is that it provides the actual radon measurements specific to the soil of the development site.  The equipment can be used to map the whole site to provide a clear and accurate understanding of the actual radon levels and then informed decisions can be made if radon mitigation is required and how extensive they need to be.

The Markus 10 will measure the radon content within 14 minutes after starting the measurement and only 18 minutes waiting time is required between each measurement.

The instruments are particularly good for pre planning ground investigation work and can be used before designs or construction works start on new developments or brownfield land development. In-situ testing allows for an enhanced assessment of radon potential of shallow soils rather than sole reliance on the Radon Atlas.

Using the Markus 10 when assessing development land could mean that a site that may not look viable according to the Radon Atlas actually is or that any radon issues are captured at the pre planning phase so development designs can be adapted before designs are finalised for planning applications.
