The Highland Council’s community services commissioned Public Health England (PHE) last year to test around 1,150 homes at the highest risk from radon gas. Of the near 700 test kits returned and analysed, there are 95 homes where the council will be taking action to reduce radon levels.

Hundreds of test kits have been returned and 95 properties will need action to reduce radon levels.

These houses were in parts of Badenoch and Strathspey; Wester Ross Strathpeffer and Lochalsh; Caol and Mallaig; Landward Caithness; East Sutherland and Edderton; Dingwall and Seaforth; and Aird and Loch Ness Wards. The Community Services has written to all tenants who returned their test kits to advise of the results.

Highland Council investigations into the presence of naturally occurring gas radon gas at its schools and other buildings are ongoing and an update on them is expected after the October holidays.

Radon is produced by the radioactive decay of rocks and soil. High levels are normally tackled by fitting ventilation equipment.
