[Measurement Method] Air dose rates were measured at the following locations: one location at the main gate of schools, etc. (on the premises), one location at an entrance (in the case of more than one entrance, the one highly used by lower grade children and students), and five locations at the center and four corners of schoolyards, playgrounds, etc. Monitoring results are the average values of five readings at each monitoring location. (Monitoring results at schoolyards, playgrounds, etc. are the overall averages of the average values at five locations.) The highest and lowest values were selected from the average of the values measured at the height of 50cm above the ground for nurseries, kindergartens and elementary schools (also measured at the height of 1m only at the center of schoolyards, playgrounds, etc.), at the height of 1m for junior high schools, senior high schools and specialized training colleges, and at the height of 50cm and 1m for special support schools and miscellaneous schools. Regarding monitoring locations where air dose rates were measured at multiple points, the highest and lowest values were selected from the average of values for all those points.
