Aichi Geiger Count

This is in Japanese, but here are the essentials, just in case you want to know how safe the air is in Aichi Prefecture, a measure of gamma rays.
The first section of numbers is a record of the readings in microsieverts per second. The first column on the left 測定日時 is the date and time the reading was taken, and the second column 放射線量 is the number of microsieverts per second.
