Medical personnel involved in interventions in interventional radiology are exposed to occupational exposure and are therefore at risk of radiation-induced diseases. Therefore, individual dosimetric control is an essential component of ensuring safe working conditions for medical staff and is regulated at the international and state levels [1, 2].The purpose of the study is to determine the levels of occupational exposure of interventional surgeons and nurses performing interventional procedures in the departments of the Donetsk Clinical Territorial Medical Association (DСTMA).
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...
Conclusion and recommendations
The average annual effective doses of medical personnel working in interventional departments from 2012 to 2018 did not exceed the exposure level of 20 mSv / year. Individual dosimetry using several sensors and dosimetric control of eye and hand irradiation will more accurately determine the dose received by medical personnel. Moreover, the level of exposure to the eyes of personnel, especially cardiovascular surgery and neurosurgical departments, may be higher than recommended by the International Commission on Radiation Protection .
