Study of scattered radiation during fluoroscopy in hip surgery

Abstract

ObjectiveTo measure the scattered radiation dose at different positions simulating hip surgery.Materials and MethodsWe simulated fluoroscopy-assisted hip surgery in order to study the distribution of scattered radiation in the operating room. To simulate the patient, we used a anthropomorphic whole-body phantom, and we used an X-ray-specific detector to quantify the radiation. Radiographs were obtained with a mobile C-arm X-ray system in continuous scan mode, with the tube at 0º (configuration 1) or 90º (configuration 2). The operating parameters employed (voltage, current, and exposure time) were determined by a statistical analysis based on the observation of orthopedic surgical procedures involving the hip.ResultsFor all measurements, higher exposures were observed in configuration 2. In the measurements obtained as a function of height, the maximum dose rates observed were 1.167 (± 0.023) µSv/s and 2.278 (± 0.023) µSv/s in configurations 1 and 2, respectively, corresponding to the chest level of health care professionals within the operating room. Proximal to the patient, the maximum values were recorded in the position occupied by the surgeon.ConclusionWe can conclude that, in the scenario under study, health care professionals workers are exposed to low levels of radiation, and that those levels can be reduced through the use of personal protective equipment.

Pattern of radiation safety measures and security culture in four major hospitals, Ismailia, Egypt

“…In Hospital C, there is no statistically significant difference (p>0.05) between the mean background radiation and the mean leakage radiation behind shield in room 1 although the mean radiation level behind the shield (709 nsv/h) is higher than that of background radiation (81 nsv/h). In room 2, there is a statistically significant difference (p<0.05) between the mean background radiation and the mean leakage radiation behind shield (Table , 5). Regarding linear accelerator unit in nuclear medicine department, there is no statistically significant difference (p>0.05) between mean background radiation levels and the mean leakage radiation in control console of accelerator, outside accelerator area, control console of simulator and outside simulator area respectively.…”

“…For longer procedures such as coronary interventions, peripheral vascular interventions, heart catheter, angiography, etc., the dose received by physicians and attendant staff is almost entirely attributable to radiation scattered from the patient [4] . Radiation safety and protection is thus necessary in order to reduce the levels of that exposure [5] . According to safety regulations, X-ray room must be effectively shielded and personal protective equipment must be available for the staff.…”

Knowledge and practices of radiation safety among healthcare workers in Ismailia city hospitals, Egypt

“…About 7500 and 5700 cases of radiation induced cancer among Japanese and United States population, respectively are attributed to the radiation dose from diagnostic X-ray processes each year [2] . Radiation safety and protection is thus necessary in order to reduce the levels of that exposure [4] . Education is the significant and the key measure of managing radiation safety and each individual using radiation needs to know what radiation is and how to handle it, as there is a growing number of diagnostic radiology procedures performed yearly which increases the concern for practicing radiation safety [5] .…”
