The exposures of 128 examinees .received upper G.I.T (gastro-intestinal tram) X-ray examination are measured. The reference point of the maximum body surface exposure given is at the middle of stomach. The average of this point is (4.97±1.94) × 10-4C.kg-1 person-1 examination-1 and (1.33±0.28)×10-4C.kg-1.min-1.展开更多
