Analysis on the use of radiation protective equipment for the accompanying examinees

Abstract

Objective: To investigate the situation of wearing protective equipment in the process of X-ray radiation examination (including DR and CT) in a 3A general hospital, so as to provide technical basis and solutions for better reducing the radiation dose of accompanying patients. Methods: From November 1, 2018 to June 30, 2019, the accompanying examinee 6 who had to stay in the examination room during the radiology examination (X-ray and CT examination) of a 3A general hospital from June 1, 2018 to June 30, 2019 was selected 535 people were divided into three groups according to whether they were reminded and instructed to wear protective equipment: group A was not reminded (group A) , group B was reminded to wear protective equipment, and group C was reminded and instructed to wear protective equipment (Group C) . Results: The wearing rates of protective equipment of the three groups were 35.0% (744/2126) , 85.2% (1858/2181) and 91.0% (2028/228) , and the complete wearing rates were 15.0% (319/2126) , 54.8% (1195/2181) and 88.0% (1960/228) , respectively. 4% (1450/3060) , 28.6% (876/3060) , 24.0% (734/3060) , respectively. 523 patients refused to wear protective equipment. The main reasons were emotion (33.8%, 177/523) and time (32.5%, 170/523) . Conclusion: The intervention of radiation workers can effectively improve the correct wearing rate of protective equipment and reduce the radiation exposure of accompanying people.
