Anytime that someone travels by air they will receive a dose of ionising radiation in the form of cosmic radiation. The aim of this study was to estimate the average dose of cosmic radiation received by a member of the Irish public over the period of a typical year due to air travel. The frequency of air travel by Irish residents to several regions was determined using data from various sources. The total dose that one would receive for a typical flight to and from the region was then calculated using software available for flight crews to estimate the radiation dose that they have received through flying. The annual effective dose for an Irish person as a result of cosmic radiation from air travel was estimated to be 68 µSv.
