|Annual natural exposure||2.1 mSv/a|
|Living at sea level||0.3 mSv/a|
|Transatlantic flight||up to 0.1 mSv|
|Chest X-ray||0.01 – 0.03 mSv|
|Whole-body computer tomograph||10 - 20 mSv|
Thus, X-rays in the field of medical applications and various natural radioactivity cause a much higher radiation exposure than being near a radiometric measurement.
