Really Are Protective Aprons Leaded? Proposed Radiometric Methodology for Assessing Security Protective Devices

摘要

Everyday health professionals, especially cardiologists, performed interventional procedures using fluorosco-py-based equipment; erroneously assumes that working with a nearby one milliampere values for tube current, imply a low radiation dose to the patient and the close personal, but the act of observing the path of catheters for several minutes, involves taking risk values of scattered radiation if they're not using elements of radioprotection (ERP). This is due to the fact that the interventional staff is in the vicinity of the image intensifier tube or flat panel, where the radiation forming the angiographic image is captured. In this context, radiation protection is essential, the specific characteristics of aprons, thyroid and gonads shields were investigated to determine their integrity and attenuating capacity of radiation. This research allowed us to evaluate shielding capacity of more than 70 ERP of the three most important radiology centers in the cities of Valparaiso and Vina del Mar in Chile, for which an instrumental method and a methodology to replicate measurements in an equivalent context was created.
