High levels of radon linked to lung cancer

Up to 86% of the radiation that Irish people are subjected to comes from natural sources such as radon gas emitted from the earth.

Radon is the principal source of radiation in the Irish population, contributing over 55% to the average radiation dose.

Less than 1% of radiation exposure comes from high-profile artificial sources such nuclear plants like Sellafield or Chernobyl or from the workplace, a new study shows.
