BENEFIT, DAMAGE AND FEATURES OF USE OF C-ARCS

Abstract

Introduction. The increase in patients with gunshot and mine-explosive injuries has led to the need for a significant increase in the use of C-shaped X-ray systems. And that's the reason for studying the features of the effective and safe use of C-shaped systems during surgical interventions with the minimization of the dose load on medical personnel.

Methods. Dosimetric measurements were carried out during radiation examinations using 15 different types C-shaped X-ray systems, measured radiation dose rates of personnel at workplaces.

Results. The analysis of the results of dosimetric measurements was carried out according to the following characteristics: the dose power received at the workplace by personnel at the level of the head, chest, gonads and legs; the ratio of the exposure mode to the radiation and dose received by the personnel; the difference between the doses that were measured at the level of different parts of the personnel's body, according to the direction of the radiation beam; analysis of the results of radiation control, measured values of the dose rate, reduced to the value of the standard workload, according to DSanPiN 6.6.3-150-2007.

Conclusions. Permissible dose rates were calculated based on the obtained dosimetric measurements. The results of the comparison with the regulations and shows ustheir danger (in some cases, the maximum permissible dose was exceeded by 2.5 times). Вased on this we consider it absolutely necessary to use X-ray screens and personal protective equipment in operating rooms.
