The lecture on radiation has been given in 2nd grade physics class in NIT Fukui college for a long time. In this report, we will discuss the changes in the lecture materials and questionnaire survey to measure the effectiveness of education in this decade. In recent surveys, text mining techniques were applied to analyze the free-form responses, and it was revealed that the attitude of students was significantly changed by the lecture. The results of the survey suggest that the radiation education had a positive effect on the students to change the awareness of radiation.
