摘要：

The International Commission on Radiological Protection has recommended the use of a new dose quantity ''effective dose''. The doses to 22 organs of the human body are required for a formal calculation of this quantity. This paper shows that a quick estimate of the effective dose received by a patient from a barium meal or a barium enema can be made by multiplying the measured dose-area product for the complete examination by an appropriate conversion coefficient. Despite the varied techniques used for barium examinations, such an estimate is unlikely to be in error by more than 25%.
