Fluorine was determined in the iliac crest bones of patients and in ribs collected from post-mortem investigations by particle-induced gamma-ray emission based on the 19F(p,p'gamma)19F reaction, using 2.0/2.5 MeV protons. The results indicate that for 68% of the human samples the F concentration is in the range 500-1999 microg g(-1). For comparison purposes fluorine was also determined in some animal bones; in some animal tissues lateral profiles of fluorine were measured.
采用基于(^{19}F(p,p'\gamma)^{19}F)反应的粒子诱导γ射线发射法，使用能量为2.0/2.5 MeV的质子，测定了患者髂嵴骨和尸检采集的肋骨中的氟含量。结果表明，68%的人体样本中氟浓度在500 - 1999μg g⁻¹范围内。为作比较，还测定了一些动物骨骼中的氟含量；并测量了一些动物组织中氟的横向分布情况。
