Outline of Final Research Achievements

The purpose of this research is to contribute to the improvement of education on atomic energy and radiation by developing the simple cloud chamber that can be easily used at schools. We developed an S cloud chamber which enabled us to observe the track of radiation by using chemical freezing mixture instead of usual dry ice. Moreover, we used the S cloud chamber at schools to clarify the effectiveness and suitability as teaching materials.　By developing an S cloud chamber, it seems that the track of radiation can be observed more and more easily.
