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 @, A and B at Nagaoka University of Technology.
The readings at point C are measured by pocket dosimeter every week. (average dose per hour)
To measure the radiation dose rate at the point C by the pocket dosimeter has finished on December, 2011.
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 (Sv/h).
The recommended maximum radiation dose rate in a place of daily life is
250 Sv/3 months.

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