BODY SURFACE EXPOSURE DISTRIBUTION OF EXAMINEES RECEIVED UPPER G.I.T. X-RAY EXAMINATION

摘要

A special cloth for keeping LiF(Mg,Cu,P)TL dosimetry elements is worn by examinees. The exposures of 128 examinees received upper G.I.T (gastro-intestinal tract) 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) x10~(-4)C·kg~(-1) person~(-1) examination~(-1) and (1.33±0.28)x10~(-4)C·kg~(-1)·min~(-1).
