Abstract :
Objective: To evaluate the radiation dose received by staff
in spine surgeries, including those who are not considered
occupationally exposed workers. Methods: All spinal sur-
geries performed in the same department during a period
of 12 months were evaluated with regard to the exposure
of surgeons, scrub nurses, and auxiliary personnel working
in the operating room to radiation from C-arm fluoroscopy.
Radiation was measured by 15 film badge dosimeters placed
on the professionals’ lapels, gloves, and room standardized
sites. The films were analyzed in the dosimetry laboratory
by collections per period. Results: During the 12 months,
81 spinal surgeries were performed by the same team, with
surgical times ranging from 1 to 6 hours. The total radiation
dose ranged from 0.16 mSv to 2.29 mSv depending on the
dosimetry site. The most exposed site was the wrist of the main
surgeon. Conclusion: The results showed that in the spinal
surgeries in our setting, the radiation doses are low and within
legal limits. Nevertheless, constant training of professionals is
essential for radiation protection of medical staff and patients.
Level of evidence I/b, exploratory cohort study
