A Performance Evaluation of a Notebook PC under a High Dose-Rate Gamma Ray Irradiation Test

الملخص EN

We describe the performance of a notebook PC under a high dose-rate gamma ray irradiation test.

A notebook PC, which is small and light weight, is generally used as the control unit of a robot system and loaded onto the robot body.

Using TEPCO’s CAMS (containment atmospheric monitoring system) data, the gamma ray dose rate before and after a hydrogen explosion in reactor units 1–3 of the Fukushima nuclear power plant was more than 150 Gy/h.

To use a notebook PC as the control unit of a robot system entering a reactor building to mitigate the severe accident situation of a nuclear power plant, the performance of the notebook PC under such intense gamma-irradiation fields should be evaluated.

Under a similar dose-rate (150 Gy/h) gamma ray environment, the performances of different notebook PCs were evaluated.

In addition, a simple method for a performance evaluation of a notebook PC under a high dose-rate gamma ray irradiation test is proposed.

Three notebook PCs were tested to verify the method proposed in this paper.
