X-Ray Dose Information

Background radiation doses vary from country to country and at different altitudes and can range from
1 to 10 milliSieverts (mSv - one thousandth of a Sv) a year. In Australia it is around 2 mSv.
In this context, while the radiation dose from medical imaging varies for each different procedure, in
comparison it is still a small fraction of our lifetime exposure to background radiation.
Table 1 is a guide how the typical effective doses from the most common imaging procedures compare
to background radiation
Table 1.
