Comment

Be aware that there are substantial differences between sexes^1,4. Also, tube voltage causes greater variation in dose in younger children¹. This calculator will give discrepant results when body parts are combined due to different estimates of conversion factors - see references 1 and 3. The dose for cardiac examinations are only relevant for adults, your age choice will be ignored.
