Outline of Final Research Achievements

Radiation training materials for university students, who will be teachers at high schools or junior high schools, were successfully developed. They were not general materials, but specialized for university teaching with high level which were difficult to understand without radiation training materials.
The first main material was a prototype beta-ray spectrometer for to learn how to measure pure beta-emitters. The spectrometer showed the maximum beta-ray energies of beta-emitters. The second main material showed relationships between activities and counts of unsealed radioactivities, which needed special facilities to use radioactive materials. The metod is so-called a tracer expreriment; however there was difference from the general method. Normal methods generate automatically radioactive waste; however, in this case, there were no radioactive wastes. Additionally, the third development was to measure gas phase’s radioactive materials which exist naturally in our environment.
