The Isle of Man has joined an ongoing radon mapping programme being undertaken across the British Isles with the publication of its first radon risk map.
This initiative aligns the island with the UK programme, which has been running for over 40 years and has surveyed more than 600,000 properties across the UK.
The new map ensures the Isle of Man is part of this long-term effort to monitor exposure to the naturally occurring radioactive gas.
Radon
Radon is produced by the decay of uranium and thorium in rocks, soil, and some building materials.
Every building contains it, but levels are usually low. The likelihood of higher levels depends on the type of ground a property is built on.
Developed in partnership with the UK Health Security Agency (UKHSA), the map shows where higher indoor levels are more likely — though not guaranteed.
It plays a key part in meeting the Isle of Man Government’s legal obligation to manage and reduce exposure.
Important Step
Clare Barber MHK, Minister for Environment, Food and Agriculture, said: “The map is an important step in raising awareness across the island. It gives households, employers, and public sector bodies the information they need to understand their risk and take action if necessary.”
Tracy Gooding, Radon Group Leader at UKHSA, added: “Radon is a public health issue that we continue to address, and this new map extends our monitoring and knowledge across the British Isles.
“We are pleased that our work has provided the Isle of Man Government with the information they need in order for them to raise awareness and meet legal obligations to reduce radon exposure.’’
Radon on Island
Homeowners in higher-risk areas are encouraged to test their property using kits available from the UKHSA website, which cost £52.80.
Guidance for radon affected areas and techniques to lower elevated levels can also be found on the website.
The Department of Environment, Food and Agriculture (DEFA) has committed to fund mitigation surveys for the small number of survey participants whose properties are at, or above, the action level.
There is currently no funding for new mitigation surveys, although the findings may inform future support.
