At the Nuclear medicine department at Skane University Hospital in Malmoe, the staff inject fluorine-18 labelled radiopharmaceuticals on a daily basis, which entails exposure of radiation dose. The Swedish Radiation Protection Ordinance prescribe dose limits, which works as requirements to prevent and minimize risks for future negative health effects to the public and workers handling ionizing radiation. The aim and purpose of the study was to study whether there is a statistically significant difference of radiation dose to the staffs fingers and body, when injecting fluorine-18 labelled radiopharmaceuticals, depending on when the removal of the peripheral venous catheter (PVK) is performed. The measurements were performed after the injection of fluorine-18 labelled radiopharmaceutical and after the imaging of the patients. In this study 44 measurements were performed, of which 22 measurements were performed after the injection of 18F-labelled radiopharmaceutical and 22 measurements after the medical imaging. The measurements were performed on 11 staff members in the Nuclear Medicine department in Malmoe. The results of 22 measurements showed a mean value of the equivalent doses to the fingers after injection showed 0,20 μSv/MBq and after the medical imaging of the patient of 0,18 μSv/MBq. The mean value of effective dose was entailed to 0,004 μSv/MBq after injection and 0,003 μSv/MBq after imaging. A Mann-Whitney U-test was performed and reported a p-value of >0,05, which indicates that there is no significant difference in radiation dose to the staff between the two different methods of removing the PVK.
