東京電力福島第一原子力発電所の事故に伴い、福島県内各地で放射線モニタリングや除染活動が行われている。活動現場の気温は冬季に-20Cに達し、各種サーベイメータの想定使用温度の範囲外である。そこで恒温槽を用いて温度特性試験を実施し、感度の変化を実験的に調べた。

After the TEPCO Fukushima Dai-ichi NPP accident, the radiation monitoring and clean-up activities have been carrying out throughout Fukushima region. In winter, outside air temperature at the fields reaches as low as minus 20 C, which is not supposed for the use of radiation survey meters. For the purpose, temperature characteristics of several types of Japanese radiation survey meters were experimentally investigated by using a temperature-controlled chamber.
