Abstract

|
|
Purpose: This study was conducted in order to determine the relationship between the number of portable X-rays and the radiation exposure dose for emergency medical service providers working in the emergency department (ED).
Methods: A prospective study was conducted from February 15, 2013 to May 15, 2013 in the ED in an urban hospital. Six residents, seven emergency medical technicians (EMT), and 24 nurses were enrolled. They wore a personal
radiation dosimeter on their upper chest while working in the ED, and they stayed away from the portable X-ray unit
at a distance of at least 1.8 m when the X-ray beam was generated.
Results: The total number of portable x-rays was 2089. The average total radiation exposure dose of emergency
medical service providers was 0.504±0.037 mSv, and it was highest in the EMT group, 0.85(0.58-1.08) mSv. The
average of the total number of portable X-rays was highest in the doctor group, 728.5(657.25-809). The relationship
between the number of portable X-rays and the radiation exposure dose was not statistically significant(-0.186,
p=0.269).
Conclusion: Under the condition of staying away from the portable X-ray unit at a distance of least 1.8 m, the relationship between the number of portable X-rays and the radiation exposure dose was not statistically significant.
