Abstract: The present invention provides a system for dispensing radiopharmaceuticals and measuring a radiation dosage thereof. In the system, the operation of dispensing a predetermined dose of radiopharmaceuticals from a vial (21) to an syringe (31) and the operation of measuring a radiation dosage of the radiopharmaceuticals dispensed to the syringe can be sequentially conducted without a risk of radiation leaking. Therefore, the system can markedly reduce the frequency of radiation exposure and the radiation exposure dose. Furthermore, when the syringe is moved downwards from a radiopharmaceutical dispensing apparatus (101) into a radiation dosage measuring apparatus (141) to measure a radiation dosage, the filling opening of the vial is displaced from a position aligned with the syringe, thus preventing radiopharmaceuticals remaining in the vial from affecting the measurement of the radiation dosage of the syringe.
