Irish people, on average, receive a higher radiation dose than the global average mainly due to relatively high radon exposure in indoor air in Ireland.

The assessment found that over 99% of the dose comes from natural radiation sources and medical exposures, such as X-rays and CT scans. 

Radon, a naturally occurring radioactive gas that can cause lung cancer contributes almost 60% of the annual dose. Medical exposures account for just over 10%.

Radioactivity from other artificial sources such as discharges from nuclear facilities abroad, the fallout from historic nuclear weapons testing and past nuclear accidents make up less than 1% of the overall dose.
