Outline of Final Research Achievements

A compact calorimeter have been developed as a field standard for external beam radiotherapy. This calorimeter can be carried and used at a medical facility. We determined absorbed dose to water in high-energy photon beam by using the calorimeter and found the results are in good agreement with those of the Japanese primary standard. This calorimeter can determined absorbed dose to water in a radiation beam from the latest radiotherapy equipment. Thus, we can provide a calibration service for the latest equipment promptly. And the people can receive medical treatment by using the latest equipment under the highly reliable quality control.
