Outline of Final Research Achievements

Real time monitoring the dose distribution of patient dose is important from the point of the improvement of the quality of the medical institution. In the present study, to acquire the radiation dose distribution in real time, the basic characteristic as the dosimeter was evaluated by combining two or more scintillators and photodetectors. The plastic scintillation fiber used for the evaluation, and the radiation detector connected with MPPC that was the photodetector was used. Conversion into the dose rate and making the programming were tried from the counting rate. The sensitivity has decreased by there are a lot of count drops, and rising of the dose in a high dose field because of in MPPC that connects the plastic scintillation fiber. It was able to be confirmed to be able to convert it into the dose also with the scintillation detector by doing an appropriate correction.
