A curriculum on radioactivity based on the concept of acceptable level has been developed for lower and upper secondary students in Japan. It consists of works in small groups and presentations. Pilot instructions were carried out in lower and upper secondary schools. It was suggested that the length of time to be spent on these instructions should be flexible between one and six school hours corresponding to teaching plans and students' abilities.Trial instructions based on the revised materials were carried out in lower and upper secondary schools in 1988. The responses of lower secondary students were preferable to those of upper secondary students in the summary questionnaire. It was thought the curriculum was available to lower secondary students, though some technical terms were too difficult for them to understand. The appropriate responses on risk-benefit evaluation in this study in lower and upper secondary schools were more than ones in our previous studies.Three surveys were carried out in 1989. First was for control-group students who enrolled the same schools and grades as the experimental groups. Second was for students who had received the instructions one year before and those who had not in a upper secondary school. Third was for students who received the instructions in a upper secondary school, and some students were examined with the questionnaire after receiving it and others were before.In the first survey it was indicated that the risk-benefit evaluation was difficult for lower secondary students who did not receive the instructions. In the second and third ones the students who received it showed higher response rate in the risk-benefit evaluation than those who did not.

日本已为初中和高中学生开发了基于可接受水平概念的放射性课程。它由小组作品和演示组成。在初中和高中进行了试点指导。建议根据教学计划和学生的能力，在1至6学时之间灵活调整这些指导的时间。1988年，根据修订后的教材在初中和高中进行了试点指导。在总结问卷中，初中生的反应优于高中生。人们认为该课程适合初中学生，尽管一些技术术语对他们来说太难理解。本研究中初中和高中对风险收益评估的适当反应比我们以前的研究要多。 1989年进行了三次调查。首先是针对与实验组就读相同学校和年级的对照组学生。其次是针对一年前接受过指导的学生和未在高中就读的学生。第三个是在高中接受指导的学生，有的学生在接受指导后进行了问卷调查，有的学生在接受指导之前就进行了问卷调查。第一个调查表明，对于没有接受指导的初中生来说，风险收益评估是困难的。在第二个和第三个实验中，接受该方案的学生在风险收益评估中的响应率高于未接受该方案的学生。
