摘要
目的:研究小白鼠对γ射线的吸收规律,探讨其用于人死后经过时间推断的可能性。方法:死亡组织会随时间的推移而丢失水分,从而质量和密度发生一系列的变化,这些变化将使死亡组织对γ射线的吸收规律发生相应的变化。用FH463A自动定标器进行连续数日的多次测量,得出死亡组织对γ射线的吸收情况和死后经过时间之间的曲线,推出两者之间的关系。结论:死后经过时间和小白鼠对γ射线的吸收规律之间有着必然的联系,利用死亡组织对γ射线的吸收情况来进行死后经过时间的推断是可行的。
Objective： The probability that the law of white rat imbibitions γ ray can be used to explore human dead time is studied. Methods： With the time passing, dead tissue will lose its＇ moisture; This will lead to mass and density got changed; All these changes will get law of dead issue imbibitions γ ray changed. Autoscaler FH463A is used to measure for many times in several days constantly and the correlation curve between the absorbing amount of dead issue on γ ray and dead time is gotten, so does the relation between two of them. Results： Dead time and the absorbing albino rat ony ray have certain relation and it is feasible to infer dead time with the absorption of γ ray on dead tissue.
