The paper compares information on the values of the equivalent dose to hands that are read from ring DXT-RAD thermoluminescent dosimeters of the manipulation nurse in the Positron Emission Computed Tomography Department of the All-Ukrainian Center for Radiosurgery at the Feofania Clinical Hospital with calculations of the equivalent dose to hands that are performed using the VARSKIN+ computer code. Personnel who manipulate radiopharmaceuticals in the Positron Emission Computed Tomography Department are under permanent individual dosimetric control using thermoluminescent dosimeters to determine the effective dose from beta and secondary photon radiation created by the 18F radionuclide in the 2-[18F] -2-deoxy-D-glucose, as well as ring dosimeters to determine the equivalent dose to the hands for comparison with category A dose limits. During the study, information from the ring dosimeters of three manipulation nurses of the Positron Emission Computed Tomography Department was used regarding the dose accumulated over ten months. Over this period, information was extracted from the department's documents, in particular from journal entries, about the daily number of manipulations performed, the amount of activity administered to each patient, the total activity of radiopharmaceuticals, the evidence of the use of protective equipment during the manipulations, reports of cases involving radioactive substance contact with skin, gloves, etc., which can affect the measured dose on hands. The average time spent on each stage of manipulation with 18F-FDG was determined experimentally. Comparison of the calculated data and data obtained in the processing of thermoluminescent dosimeters for the same time, taking into account the number of operations performed by the staff and the amount of activity prepared for administration to patients, allowed determining the possibility and effectiveness of using calculations for planning and evaluation of the equivalent dose in manipulations at the Positron Emission Computed Tomography Department, assessing the need for additional local protection against ionizing radiation for hands during injections or optimization of manipulation procedures and determining the obligation to evaluate equivalent doses using thermoluminescent dosimeters.
