A drum-type volume source calibration phantom is provided, which comprises a drum-type container; a plurality of plate groups stacking up inside the drum-type container, at least one slab of radioactive source, each of which is disposed between the adjacent plate groups and comprises a plurality of radionuclides. The present invention further provides a calibration method that starts by the step of providing a radioactivity test for each drum-type volume calibration phantom. Then, a calibration relationship of density vs. counting efficiency corresponding to the several different drum-type volume source calibration phantoms is performed in a waste curie monitor. Finally, a characteristic of photonic energy dependency is measured for a modification factor.
A drum-type volume source calibration phantom is placed in a detector, there is an accommodating space inside the detector for receiving a plurality of radioactivity detectors, and the drum-type volume source calibration phantom comprising:
A calibration method for drum-type volume source calibration phantom comprising steps:
