Abstract
The effective atomic numbers for total photon interaction in bone, muscle, liver, spleen, fat, and water are determined and found to decrease up to 50% as the energy increases from 10 to 200 keV. Muscle, spleen, liver, and water are found to behave in an approximately similar manner in this energy region, as far as photon interaction is concerned.
摘要
测定了骨骼、肌肉、肝脏、脾脏、脂肪和水中总光子相互作用的有效原子序数，发现随着能量从10keV增加到200keV，有效原子序数降低了50%。就光子相互作用而言，在该能量区域内，肌肉、脾脏、肝脏和水的表现大致相似。
