| 内容記述 | A new method for estimation of the elapsed time after a nuclear explosion from a given radioactive fallout has been developed wherein the activity of 9595Nb is measured by a Ge (Li) gamma-ray detector with high resolution. The elapsed time after the nuclear explosion was calculated by this method from the two measured values of the activity of 95Nb at a given time intervals in the highly radioactive fallout particles due to the seventh Chinese nuclear test explosion on 24 December 1967. The results were in fairly good agreement with the true values of the elapsed time, and also with the estimated values of the elapsed time obtained from the activity ratio of 95Zr to 95Nb. The expected errors for the results and the necessary measurement accuracies for the number of the atoms of 95Nb and the time intervals to estimate the elapsed time within the errors 1 to 2 days, are given in the tables. | |||||||
