The radiation dose rates are monitored everyday at the following spots
①, ②, ③ and ④ at Nagaoka University of Technology.
*The readings at point ④ are measured by pocket dosimeter. (average dose
per hour)
Since April 11, we have reported only the pocket dosimeter readings at
point ④, since all the values determined at the four points so far have
been similar and lower than usual levels.

Radiation dose rates (microsieverts per hour)
The table indicates radiation dose rates in air at the spots, and the values are shown as microsieverts/hour (μSv/h).
The recommended maximum radiation dose rate in a place of daily life is
250 μSv/3 months.
