Background and purposeWe aimed to compare the performance of the ZeroGravity (ZG) system (radiation protection system composed by a suspended lead suit) against the use of standard protection (lead apron (LA), thyroid shield, lead eyeglasses, table skirts, and ceiling suspended shield) in neuroangiography procedures.Materials and methodsRadiation exposure data were prospectively collected in consecutive neuroendovascular procedures between December 2014 and February 2015. Operator No 1 was assigned to the use of an LA (plus lead glasses, thyroid shield, and a 1 mm hanging shield at the groin) while operator No 2 utilized the ZG system. Dosimeters were used to measure peak skin dose for the head, thyroid, and left foot.ResultsThe two operators performed a total of 122 procedures during the study period. The ZG operator was more commonly the primary operator compared with the LA operator (85% vs 71%; p=0.04). The mean anterior-posterior (AP), lateral, and cumulative dose area product (DAP) radiation exposure as well as the mean fluoroscopy time were not statistically different between the operators’ cases. The peak skin dose to the head of the operator with LA was 2.1 times higher (3380 vs 1600 μSv), while the thyroid was 13.9 (4460 vs 320 μSv), the mediastinum infinitely (520 vs 0 μSv), and the foot 3.3 times higher (4870 vs 1470 μSv) compared with the ZG operator, leading to an overall accumulated dose 4 times higher. The ratio of cumulative operator received dose/total cumulative DAP was 2.5 higher on the LA operator.ConclusionsThe ZG radiation protection system leads to substantially lower radiation exposure to the operator in neurointerventional procedures. However, substantial exposure may still occur at the level of the lens and thyroid to justify additional protection.

Therapeutic Procedures

The increasing utilization of radiation for diagnostic and therapeutic procedures has provided impetus for improved strategies of radiation protection for interventionalists. The associated discomfort, disability, and career-shortening effects of lead aprons for heavy fluoroscopy users have served as an impetus for the development of lighter and more comfortable models. A suspended radiation protection system employs the use of a “weightless” shield resembling a thick large lead apron with head shield and arm shields. The shield moves with the operator like a garment, providing extensive protection without orthopedic strain or discomfort while maintaining full user functionality. Utilization of a suspended radiation protection system provides the operator with optimum radiation protection, without any additional weight, and maintains procedural flexibility.

Psychophysiological Examination

The link between the health level of an employee and his professional reliability is currently obvious and does not require additional proof. The implementation of measures aimed at reducing the risks of developing emergency situations due to the fault of the human factor at nuclear facilities is an important element of the radiation protection system. In order to achieve the above goals of the organization in accordance with Federal Law No. 170-FZ of 21.11.1995, the performance of certain types of work in the field of atomic energy use requires special permits from Rostechnadzor. A prerequisite for obtaining such a permit for a specialist is the absence of psychophysiological contraindications based on the results of a psychophysiological examination. In this study, the analysis of the results of psychophysiological examinations (hereinafter referred to as PPhE) of employees of atomic energy facilities, carried out by specialists of the A.I. Burnasyan Federal Medical Biophysical Centre in 2020.
