Improvement of Track Counting Accuracy and Efficiency in the Fission Track Method.

Abstract

In the fission track method, the counting of fission track is performed with the naked eye using a microscope, and the researcher experiences intense eye strain when examining a large number of samples. As a result, counting errors are more likely to occur, requiring more time to complete the work. The present study has been undertaken with the aim of increasing the accuracy and efficiency of track counting in order to solve the above-mentioned problems associated with the fission track method. The following conclusions were obtained.1. The accuracy of track counting in the fission track method can be improved by introducing photomicrography to the conventional method of track counting with the naked eye.2. A digital counter that displays track numbers automatically has been made, but it requires further improvement of accuracy for practical application.
