Summary

Both syringe type as well as the volume of the patient doses of radiopharmaceuticals can cause high residual activity in the syringes during application to patients. Therefore, we aimed to investigate the effects of syringe type and differences in volume and personnel on residual activity and adsorption. Injection of radiopharmaceuticals needs special attention. We concluded that less care during injection or preparation of the radiopharmaceutical in syringes will lead to a decrease in the accuracy of radioactive dose received by the patient and to an increase in environmental contamination due to the residual radioactivity in the syringes.
