This is a prospective observational study of radiation exposure by radiologists using interventional therapy with C-arm fluoroscopy between October 2012 and January 2013. To measure the effective dose (ED) of the left chest (DPM - 127) of the radiologist, Hitachi Aloka Medical, Inc. (Tokyo), one side of the wristwatch (DPM - 227, Hitachi Aloka Medical Corporation) Was used. ,Tokyo Japan). To measure the ED, adjust the height of the fluoroscope until the operating table is at the center between the X-ray generator and the image intensifier [1]. The X-ray field of X-ray fluoroscopy is also adjusted at the center of the operating table. In each procedure, when a radiologist used a C-arm fluoroscope (OEC 9800 PLUS GE healthcare, Salt Lake City, Utah) to capture the first X-ray image of each procedure, observe the position of the radiologist, The places are classified according to groups A, M, and P (Figure 1). According to the position of the dosimeter in the chest of the X-ray camera, if it is located beside the moving support structure of the fluoroscope, the position is M. If located before the moving support structure, the position is A. In order to keep constant the distance from the X-ray generator to the A, M, P group during surgery, the C arm of the fluoroscope was placed closest to the mobile device (Fig. 1).
In each procedure, data on age, height, weight, gender, X-ray exposure by X-ray fluoroscopy, radiation absorbed dose (RAD), and radiologist's chest and table ED data are collected.
Statistical analysis was performed with SPSS version 17. Multiple analysis of ANOVA and Turkey's age, height, weight, X-ray exposure time, RAD, ED and ED ratios (chest ED of radiation camera / ED of table side). Comparative test Gender was analyzed by chi-square test. P <0.05 is considered statistically significant
Each X-ray, fluoroscopy or CT scan provides a certain amount of radiation exposure. If you know your child's health checkup, you can estimate the radiation dose he or she receives from X-rays and other health checkups. However, it is important to understand that a small amount of radiation over a long period of time is safer than one mass exposure. The main risk of radiation exposure is cancer in later years. Researchers are still not sure how much radiation will increase the risk of cancer in the future. For most children, X-ray exposure only increases the risk of cancer, if any

In order to measure the ED the height of the fluoroscope is adjusted until the operating table is centered between the X-ray generator and the image intensifier tube. The X-ray field of X-ray fluoroscopy is also adjusted at the center of the operating table. In each procedure, when a radiologist used a C-arm fluoroscope (OEC 9800 PLUS GE healthcare, Salt Lake City, Utah) to capture the first X-ray image of each procedure, observe the position of the radiologist, The places are classified according to groups A, M, and P (Figure 1).
Radiation exposure associated with X-ray imaging configuration induced by C-arm fluoroscopy
Like other X-ray exams, fluoroscopy has several risks. The amount of radiation received by a patient depends on the individual procedure. Fluorescence can produce relatively high doses of radiation, particularly due to complicated interventional procedures requiring long-term fluoroscopy (eg placement of the stent or other device in the body). Radiation related risks associated with perspectives include the following: The probability that a person will experience these effects during the perspective process is statistically very small
