Outline of Final Research Achievements

The purpose is to develop a radiation detection system that has a composite material that can block gamma rays and a GPS function for monitoring the radiation dose. Plain weave glass fiber and glass fiber having a corrugated cardboard structure were used to prepare the shielding material. Resin has almost no radiation shielding ability, but the shielding effect is improved by adding metal powder to the resin. The powders to be added were barium sulfate and tin.
In addition, when transporting decontaminated materials, residents are very concerned about the dose rate and the current location. Therefore, we have developed a system that automatically sends the dose rate measurement results and GPS location information to the cloud server.

Academic Significance and Societal Importance of the Research Achievements

重金属を使用することなく繊維強化プラスチック（FRP）に放射線の遮蔽効果を持たせることができた．また，段ボール構造を有するFRP遮蔽材を開発し，容器としての有用性も確認することができた．
また，測定した放射線線量率とGPSモジュールで受信した位置情報を，線量率折れ線グラフやマッピング図として可視化するシステムを開発した．
これらの結果を活用することで除染廃棄物運搬における，地域住民の安心安全に寄与することが可能であると考えている．
