摘要

该研究的目的是评估利用能量色散x射线光谱法对骨矿物质含量进行化学分析的可能性，以确定身份不明的尸体的年龄，用于法医鉴定。利用能量色散x射线光谱仪对85具年龄在21 ~ 91岁之间的男女尸体的骨碎片进行了半定量化学微分析。证实了骨组织磷灰石矿物组成与年龄的关系，并提出了年龄与化学成分变化的关系式。证明了在配备能量色散x射线光谱仪的标准实验室中，利用标准矿物中化学元素含量的定量评估来确定身份不明的尸体年龄的可能性。

[Age prediction based on the examination of bone tissue elemental composition using energy dispersive X-Ray spectroscopy].

The aim of the study: Was to assess the possibility of using chemical analysis of bone mineral content by the means of an energy dispersive X-Ray spectroscopy to determine the age of unidentified corpses for forensic identification. A semi-quantative chemical microanalysis of bone fragments of 85 male and female corpses aged between 21 and 91 was done through the use of energy dispersive X-Ray spectrometer. The association of bone tissue apatite mineral composition with age is confirmed and a formula, connecting age and chemical composition change, is proposed. The possibility of using quantitive evaluation of chemical elements content in the normative mineral to determine the unidentified corpse's age in a standard laboratory, equipped with an energy dispersive X-Ray spectrometer, was proved.
