Abstract

Introduction: This study intended to assess the effectiveness of application the mobile X-ray barriers (lead-wall) in reducing the radiation dose to interventionists during the brain angiography procedures. Moreover, the radiation dose of patients also evaluated to assess whether the application of lead-wall affects the patient’s dose or not? Material and method: Two interventionists took part in this study. Thermoluminescent dosimeters (TLD-100) were used to monitor the doses to interventionists. 1st-interventionist routinely used lead-wall and 2nd-interventionist didn’t use it. Demographic information of patients and radiation dose information was also recorded. Results: The results of measurements showed that the radiation dose of the 1st-interventionist was 83.57% lower than the 2nd-interventionist (p = 0.04). The amount of dose/min and DAP/min of the 1st-interventionist’s patients were 33.50% and 17.54% less than the 2nd-interventionist’s patients (p = 0.006) and (p = 0.0004). Discussion and conclusion: The results showed that application of lead wall can effectively reduce the occupational dose and it doesn’t lead to increase the patient’s dose.
