Do I need to measure my premises or premises I manage, for Radon?

Should your home or workplace fall in an area with a maximum radon potential of more than 1%, we suggest the property is subject to Radon Measurement. At MCP we are able to assist with all areas of Radon, including assessment, profiling & remedial/mitigation works.

What is the process?

Initially

• Conducting a Radon Risk Report will advise whether your home or workplace falls within a radon affected area. UKHSA recommends further investigation to measure the radon concentration should the site be above a 1% maximum potential.

Measurement

• To sufficiently measure radon within a premise, we recommend a test period of 3-months, however shorter ten day tests can be undertaken, however a longer term exposure limit is better suited to capture data during normal occupancy of the building and takes into account natural ventilation and air movement. Once the test period has concluded, readings are sent to a UKHSA approved laboratory for sample analysis.

Interpretation and Remediation

• We can accurately interpret all results and send a report to the client with recommendations in line with IRR17 (Ionising Radiation Regulations 2017).

• Should your domestic premises exceed the UK Action Level of 200 Becquerels BqM3 or your workplace premises exceed 300 BqM3, then action is required to reduce indoor radon levels below 100 BqM3.

• Radon enters property by a process called advection, where the gas moves from a point of higher pressure, ie the ground, to a point of lower presure, ie the property. To prevent radon from entering a premise, a fan can be installed to reverse the pressure or a sump can be created beneath the building to act as a point of lower pressure.
