Effective dose and organ doses during barium procedures performed using digital radiography machines were estimated and the related work practices were evaluated. Measured values of dose area product (DAP) were used for the calculation of effective doses. One hundred and thirty eight patients undergoing barium procedures were included in the study. The use of additional 0.2 mm copper filter during barium procedures effectively reduced patient doses. The effective dose during barium swallow procedure varied from 0.03 mSv to 3.5 mSv; during barium meal it varied from 0.18 mSv to 2.62 mSv; and during barium enema it varied from 0.56 mSv to 4.24 mSv. Dose auditing was done on the basis of patient doses, imaging techniques and image quality. Selection of optimized exposure factors imparted lower dose to patients during barium procedures.
