Outline of Final Research Achievements

Treatment of radiation has been emphasized in the course of study. We developed teaching materials so that students in primary and secondary schools measure radiation quantitatively themselves, train their ability to correctly interpret and evaluate the numerical values, and to judge risks. We also developed a quantitative experiment that reduces the difficulty for science teachers at primary and secondary schools by lowering the height of the barriers that they feel when using the radiation side reader of the Ministry of Education. Concerning the identification of radiation nuclides by the energy spectrum of gamma rays, experiments of three principles for people to protect themselves from external radiation, the measurement of beta ray energy distribution by tracks in a cloud chamber and the measurement of the half-life of 212Pb using 220Rn(thoron) in hot spring water.
