[Detection of ionizing radiation in operating room and hospital areas].

Background: The implementation of new medical techniques and technologies has increased occupational exposure to ionizing radiation and consequently the development of neoplasia and adverse effects on health personnel.

Objective: Have real information on the absorbed dose by healthcare personnel exposed to ionizing radiation in an operating room.

Material and methods: TLD 100 dosimeters were used to measure absorbed doses by brightness curves. 42 surgical interventions in different specialties were monitored, in each intervention a minimum of 4 dosimeters were used, with the objective of analyzing the dose based on the participation role of the individual within the operating room.

Results: A database was created with the 42 monitored surgeries, for each one a minimum of 4 analyzed data were obtained (one for each participant in the surgical procedure, that is, one for each dosimeter). The highest absorbed dose was for the specialty of traumatology, followed by otorhinolaryngology, neurosurgery and finally ophthalmology.

Conclusions: It was possible to use an adequate monitoring system to measure the dose of absorbed ionizing radiation during different surgical procedures. Based on the results, constant dosimetry follow-up monitoring of trauma specialty personnel is recommended.
