Effective doses for patients undergoing chest radiography were computed utilizing updated weighting factors, published organ doses and measured entrance doses. The effective dose decreases with beam energy (kVp) and reaches a minimum value after 100 kVp, with values when a grid is used (6.90 microSv) being 145% higher at this energy than when no grid is used (2.82 microSv). The uncertainties associated with derivation of the tissue weighting factors are shown not to affect the point at which… CONTINUE READING
