“…[6] However, the available literature on the extent of radiation exposure to ICU personnel is scarce and relates mainly to the level of scattered radiation within the ICU. [78] The conclusion of these studies is that the level of radiation exposure is extremely low and does not pose a hazard to ICU personnel. [78] None of these studies have considered the additional radiation exposure to ICU personnel involved in the management of critically ill patients in the Radiology Department.…”

Background and Aims:With the expanding use of diagnostic and therapeutic radiological modalities in critically ill patients, doctors working in Intensive Care Units (ICUs) are increasingly exposed to ionizing radiation. This risk of radiation exposure occurs not only during bedside radiologic procedures, but also when ICU physicians accompany patients to radiology suites. The aim of this study was to quantify levels of radiation exposure among medical professionals working in the ICU.Materials and Methods:The study was carried out prospectively over 6 months in the ICU of a tertiary-referral cancer hospital. Two teams consisting of 4 ICU resident doctors each were instructed to wear thermoluminescent dosimeters (TLDs) during their duty shifts. Standard radiation protection precautions were used throughout the study period. TLDs were also placed in selected areas of the ICU to measure the amount of scattered radiation. TLDs were analyzed at the end of every 3 months.Results:The readings recorded on TLDs placed in the ICU were almost immeasurable. The mean value of residents' radiation exposure was 0.059 mSv, though the highest individual reading approached 0.1 mSv. The projected maximum yearly radiation exposure was 0.4 mSv.Conclusions:If standard radiation safety precautions are followed, the cumulative radiation exposure to ICU resident doctors is well within permissible limits and is not a cause of concern. However, with the increasing use of radiological procedures in the management of critically ill patients, there is a need to repeat such audits periodically to monitor radiation exposure.

“…Even after taking these additional sources of radiation exposure into account, we found that the cumulative radiation exposure was negligible. Similarly, another study looked into the radiation exposure to ICU nurses and found that the exposure was well below the permissible level [13].

Radiation protection programs aims to reduce the radiation dose to the lowest possible level under the Dose Limit (DL) limit by the national or international laws, while the dose monitoring programs working as scale used to evaluating the efficiency of these programs and tools. In this study, the average of the annual Eff dose for the intensive care units at Hamad General Hospital (HGH) is less than the 50% of DL. It was aiming also to evaluate the efficiency of the radiation safety requirements (especially the shielding Adequacy) for the non radiation workers at oncology centers, hence several monitors were installed in chosen locations outside the radiation treatment machine from 2007 to 2011.

“…The results indicated that the scattered radiation from X-rays exhibited a directional distribution, and the position where the technician stood affected the absorbed scattered radiation doses. As suggested by previous studies, the scattered radiation induced by X-ray exposure at a distance of 2 m was attenuated to background radiation levels (U.S. = 8.493 μGy per day) [26]. In the operating room, the measured background radiation dose was 0.06 μGyh í1 , i.e., the dose was 1.44 μGy per day.…”

“…As shown in Table 1, except for the X-ray examinations on the lumbar vertebrae and the perspective X-ray, the induced radiation was attenuated to background radiation levels. According to the provisions relevant to radiation safety, technicians should use portable lead shields when the patient stands within a range of 1 foot for the purpose of protecting the other patients and medical staff from unnecessary exposure and to reduce the radiation doses at work [26][27][28]. In this study, the experimental data provide professional knowledge on clinical radiation exposure levels for nurses in hospitals.…”

Abstract. This work aimed to investigate the spatial distribution of scattered radiation doses induced by exposure to the portable X-ray, the C-arm machine, and to simulate the radiologist without a shield of lead clothing, radiation doses absorbed by medical staff at 2 m from the central exposure point. Material and method: With the adoption of the Rando Phantom, several frequently X-rayed body parts were exposed to X-ray radiation, and the scattered radiation doses were measured by ionization chamber dosimeters at various angles from the patient. Assuming that the central point of the X-ray was located at the belly button, five detection points were distributed in the operation room at 1 m above the ground and 1-2 m from the central point horizontally. Results: The radiation dose measured at point B was the lowest, and the scattered radiation dose absorbed by the prosthesis from the X-ray's vertical projection was 0.07 ±0.03 μGy, which was less than the background radiation levels. The Fluke biomedical model 660-5DE (400 cc) and 660-3DE (4 cc) ion chambers were used to detect air dose at a distance of approximately two meters from the central point. The AP projection radiation doses at point B was the lowest (0.07±0.03 μGy) and the radiation doses at point D was the highest (0.26±0.08 μGy) .Only taking the vertical projection into account, the radiation doses at point B was the lowest (0.52 μGy), and the radiation doses at point E was the highest (4 μGy).The PA projection radiation at point B was the lowest (0.36 μGy) and the radiation doses at point E was the highest(2.77 μGy), occupying 10-32% of the maximum doses. The maximum dose in five directions was nine times to the minimum dose. When the PX and the C-arm machine were used, the radiation doses at a distance of 2 m were attenuated to the background radiation level. The radiologist without a lead shield should stand at point B of patient's feet. Accordingly, teaching materials on radiation safety for radiological interns and clinical technicians were formulated.
