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。
People have long talked about nuclear discoloration due to the dangers and mysteries of nuclear radiation. In 2011, the nuclear leak triggered by the Japan Earthquake caused the public to panic again. By deeply understanding the principle of nuclear radiation detection, it will help people to correctly understand nuclear radiation and thus avoid unnecessary psychological panic. Due to the uncontrollable nature of nuclear radiation and the limitations of objective experimental conditions, the related testing experiments are also very difficult to carry out in universities. Based on this, according to the rule of chemical kinetics of radioactive decay, a kinetic algorithm based on the working principle of Geiger counter was designed and a computer simulation experiment software was developed to determine the half-life of isotope. The article also describes the use of simulation software to measure the half-life of isotopes and the application of isotopic half-lives in the dating of paleontology fossils and the duration of nuclear radiation. The use of computer simulation Geiger counter software is safe, inexpensive and repeatability. The determination of nuclear radiation by computer simulation not only solves the problem of determining the safety of nuclear radiation, but also helps people master the determination methods and related The chemical principle.
