Could concentrations of high lung cancer rates in parts of Scotland and the UK be due to radon gas?
From BBC news today:
Hundreds of households have been warned to take action against high levels of a gas thought to lead to lung cancer.
More than 2,000 testing kits were sent out in Aberdeenshire and the Highlands last year and 800 homes detected higher-than-normal levels of radon.
Radon is a natural radioactive gas that comes from minute amounts of uranium found in rock and soil.
Although levels are generally low, it is believed to lead to more than 1,000 deaths across Britain each year.
Concentrated pockets were found particularly along Deeside in the north east, according to an indicative map published in July last year.
