Description of activity and work performed
Interventional procedures are performed in the departments of cardiovascular surgery, neurosurgery, endourology and spinal surgery of DСTMA. Individual dosimetric control of personnel was carried out by thermoluminescent dosimetry method using the DTU 01-M TLD reader. All personnel, who were under the dosimetric control, wore one TLD sensor at the chest level during the working day, and during the interventional procedures at the chest level under X-ray protective aprons. The DTG-4 type (LiF:Ti, Mg) TLD sensor contained two single crystals, calibrated to measure the individual dose equivalent of Нр (10).We analyzed data from 361 records of annual doses to medical personnel for the period from 2012 to 2018. The average annual, maximum and minimum effective doses received by intervention surgeons and nurses, as well as collective doses for the entire observation period were determined.
Between 2012 and 2018 the following average annual individual effective doses ± SD were obtained by intervention surgeons: in the cardiovascular surgery department 1.31 ± 0.67 mSv/year, neurosurgery 1.26 ± 0.72 mSv/year, endourology 0.75 ± 0.32 mSv/year and spinal Surgery 0.69 ± 0.19 mSv/year.
The average annual individual effective doses received by nurses were: in the cardiovascular surgery department 0.60 ± 0.35 mSv/year, neurosurgery 0.62 ± 0.54 mSv/year, endourology 0.41 ± 0.18 mSv/year and spinal surgery 0.49 ± 0.10 mSv/year. For the indicated period, the collective doses in the cardiac surgery department was 172.88 mSv, neurosurgery 43.32 mSv, endourology 47.04 mSv and in the spinal surgery department 34.18 mSv.
Not a single medical worker during the observation period received a dose exceeding 20 mSv/year. The highest annual effective doses were received by interventional surgeons and nurses in the departments of cardiavascular surgery and neurosurgery.
