“…Miller concluded in his study that dose reduction software may be a useful method for reducing radiation exposure. In order to increase patient safety and lower the lifetime occupational radiation exposure for endovascular staff, system-based radiation reduction techniques must be put into place (23). Well-established guidelines are present for the protection from occupational exposure to scatter radiation although their implementation is lacking also limited studies are available highlighting the hazards of scattered radiation to occupational exposure.…”

Radiations are extensively used for diagnostic imaging and treatment. The primary health concern for healthcare facilities is radiation safety. Patients, physicians, and staff in numerous fields, including radiology, interventional cardiology, and surgery, are concerned about radiation safety due to their increased risk of occupational exposure. Occupational exposure is the outcome of radiation exposure at work. Radiation from diagnostic imaging modalities such as computed tomography, mammography, and nuclear imaging are a modest contributor to the healthcare workers' cumulative dose exposures. Any scattered radiation exposure can be dangerous for patients and medical personnel. In order to lessen the detrimental effects of ionizing radiation, radiation protection is critical to prevent unneeded radiation exposure. The purpose of this research is to review the available information about occupational exposure of scatter radiation and proper protective methods. Fluoroscopic imaging, which employs x-rays to produce dynamic and cinematic functional imaging, is the source of the majority of radiation exposure in medical settings. Healthcare workers are exposed to low doses of ionizing radiation during various diagnostic and therapeutic procedures. Chronic exposure to low doses of radiation can have many negative effects on human health, such as cataracts and, among the most serious an increased risk of certain types of cancer. The hazards of radiation exposure among healthcare workers are well-documented in literature. To lower radiation exposure, protective equipment is vital. A lead apron, thyroid shield, and lead glasses are essential parts of protective equipment. Implementation of the guidelines for safety and protection from radiation are needed.

“…However, medical staff is exposed to radiation mainly scattered by patients when using fluoroscopy and digital subtraction radiography (DSA) in the endovascular procedure of EVAR. Therefore, as EVAR is operated more frequently in a hybrid operating room, the occupational radiation exposure becomes a raising concern to medical staff and should be monitored carefully (Miller et al 2018).…”

During interventional procedures of endovascular abdominal aortic aneurysm repair (EVAR), the dosimeter was conventionally placed on chest facing toward the surgical table, instead of the main source of scatter radiation. Purpose of this study is to evaluate the underestimation of occupational radiation exposure. Phantom experiments were performed in a hybrid operating room equipped with an interventional angiography system. Electric personal dosimeters were placed at the level of eyes, chest, abdomen, and gonad of three positions, representing the principal operator (PO), assistant operator (AO), and sterile nurse (SN). Personal dose equivalent was measured with two different orientations of radiation detection, facing the table and facing the phantom, respectively. In addition to fluoroscopy, the dose produced by digital subtraction angiography was also measured to estimate the radiation exposure of routine EVAR. In this study, staff doses of 26 EVAR cases were also collected in our hospital to correlate the estimated dose. Our results show that the facing-phantom dose normalized by dose area product of patient is significantly higher than the facing-table dose when the latter is regularly seen in clinical practice. This underestimation could be even worse at a more distant position (e.g., AO and SN) as the incident angle of scatter radiation is larger. Besides, the estimated dose is highly correlated with the on-site measured dose (R2 ~ 0.8) at chest and gonad of the PO.

“…Currently, team radiation safety performance is often evaluated through dose measurements from (live-feedback or post hoc) dosimeters or from the C-arm system, including cumulative air kerma (mGy) and dose-area-product (Gy cm 2 ). These measurements provide valuable information about the exposure of team members and patients [5] and may evaluate the impact of technological improvements (e.g., imaging protocol adjustments [6][7][8], flat-panel detectors [9]). However, dose-related measures depend on patient and procedure-related factors (e.g., BMI, procedure type, difficulty), making it challenging to use them for analyzing radiation safety performance in different settings.…”
