Radioisotope Center
Since the enormous earthquake hit the northeast area of Japan, we started
to monitor the radiation dose rates on our campus, and opened the results
to the public. |
The radiation dose rates are monitored every month at the following spots
①, ② and ③ at Nagaoka University of Technology.
The readings at point ④ are measured by pocket dosimeter every week. (average
dose per hour)

Radiation dose rates (microsieverts per hour)
The figure 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.

Usual levels measured are between 0.05-0.07 μSv/h.
Usual levels measured with the pocket dosimeter are between 0.04-0.08 μSv/h. |
