Determination of the Radiation Dose Level Emitted to the Environment in Patients Undergoing Dacryo Scintigraphy

Abstract

In this study, the radiation dose rates emitted by patients who underwent dacryoscintigraphy imaging were determined. For this, the radiation dose rate was measured at the 8.23, 41.68 and 56.81 minutes after the injection of the radiopharmaceutical. In addition, 12 points were determined from the front of the patient. these points are 25, 50, 100 and 200 cm from the head level, 25, 50, 100, and 200 cm from the chest level and 25, 50, 100 and 200 cm from the foot level. 36 different measurements were made from one patient, at 3 different times, from these points. As a result of the measurements, the average dose rate varies according to time and measurement point and was found between 0.22 µSh-1 and 2.86 µSh-1.
