Abstract
<p>Medical professionals involved at intraoperative fluoroscopy are exposed to low doses of the occupational radiation exposures. The biological effects of chronic low-dose radiation on human health are complex and have not been well established. The aim of the present study is to follow up hematological parameter changes during 2 years in medical professionals exposed to ionization radiation in operating rooms.<strong></strong></p><p>22 medical professionals (medical specialists and technicians), chronically exposed to ionizing radiation of mobile C-Arm X ray machine, were selected. The seven hematological parameters were examined each time. The statistical analyses were done by Student’s t test and one way ONOVA test.</p><p>The data analysis led to the following observations: (1) the present study incorporated that the basic hematological parameters including the mean value of red blood cells (P=0.90), white blood cells (P=0.68), and platelets count (P=0.45) did not show a significant difference between two years. (2) The mean values corpuscular hemoglobin concentration, corpuscular hemoglobin, and hematocrit parameters were found disturbed low or high in some of medical professionals but their means were not significantly different between two measurements. (3)A statistically significant relation in mean value of RBCs with the duration of exposure and sex were observed.</p><p>It seems that, hematological parameters survey could not be a reliable test as the biological indicator of long term exposure to very low dose of radiation exposure in medical professionals which their physical dosimetry values are lower than dose limits. </p>
Highlights
Medical specialists and technicians in the intraoperative fluoroscopy are exposed to long-term of low-level radiation during surgical procedures
Seven Hematological parameters (HPs) were considered for this study including white blood cells (WBC), red blood cells (RBC), and platelet count (PLT), hematocrit (HCT), mean corpuscular hemoglobin concentration (MCHC), and mean corpuscular hemoglobin (MCH) and hemoglobin (Hb) which were measured in all subjects
We observed that collective mean values of HPs are within the normal range for medical professionals (MPs)
Summary
Medical specialists and technicians in the intraoperative fluoroscopy are exposed to long-term of low-level radiation during surgical procedures (orthopedic, neurosurgery, urology). These exposures to the surgical team typically come from primary or scatter radiation. The exposure rate for radiation scatter from a mobile C-Arm machine at 2 foot distance from the radiation field is approximately 5millirem/min at 2. Some studies indicated that primary radiation received by medical professionals (MPs) during mobile C-Arm fluoroscopy maybe higher than predicted (Singer, 2005). Numerous studies (Clerinx, Buls, Bosmans, & De Mey, 2008; Klein et al, 2010; Shortt, Al-Hashimi, Malone, & Lee, 2007; Whitby & Martin, 2014) revealed that the occupational radiation doses to the medical specialists and other technicians working with the fluoroscopy are rising health concern
