Abstract
In 2006, Japan Nuclear Fuel Limited (JNFL) began "the delivery lesson on radiation" in order to promote understanding of radiation for the elementary and junior high schools students. Currently, "the delivery lesson on radiation" is aimed mainly for the junior high school students. About 1800 students per year take the lesson. We will report the effects and tasks of "the delivery lesson on radiation" based on the results of the questionnaire filled out before and after the lesson.
