利用计算机模拟测定同位素半衰期

由于核辐射的危险性和神秘性,长期以来人们谈核色变。2011年,日本大地震引发的核泄漏让社会大众再次陷入恐慌之中。通过深入理解核辐射检测原理,将有助于人们正确认识核辐射,从而避免不必要的心理恐慌。由于核辐射的难以控制性以及客观实验条件的限制,与之相关的检测实验在大学里也很难开展。基于此,根据放射性蜕变的化学动力学规律,尝试设计了基于盖革计数器的工作原理的动力学算法,开发了计算机模拟实验软件,用于测定同位素的半衰期。本文还介绍了利用模拟软件测定同位素的半衰期的过程,以及同位素半衰期在测定古生物化石年代和核辐射持续时间上的应用。计算机模拟盖革计数器软件的使用具有安全性、廉价性和可重复性,通过计算机模拟测定核辐射,不仅解决了测定核辐射的安全性问题,也将有助于人们通过实验掌握测定方法以及相关的化学原理。

Computer simulation software to determine isotope's half-life

Because of the risk and mystery of nuclear radiation,people have long been scared on hearing this subject.In 2011,the Japan earthquake triggered nuclear leakage,which led the public into panic again.As a professional postgraduate on chemistry,I believe that in-depth researching on nuclear radiation detection principles will help people achieve a correct understanding of nuclear radiation,thus avoid unnecessary psychological panic.Since the objective difficulty to control nuclear radiation and the lack of experimental conditions,it is difficult to carry out related detection experiments in universities.On account of this,we try to design a Geiger counter on the working principle of the dynamic algorithm based on the chemical kinetics of radioactive decay,and then develop a new kind of computer simulation software to determine the half-life isotopes.This article also describes the process of using simulation software to determine the half-life isotope,as well as the application of isotope’s half-life,such as determination of paleontological fossil’s age,duration of radiation.Computer simulation software for use with safety,cheap and repeatability.Through the computer simulation detection of nuclear radiation,it will not only solve the safety issues about the determination of nuclear radiation,but also help people master the determination method and the principles of chemistry.
