Abstract

Background/Objectives: Extracorporeal shock wave lithotripsy is a non-invasive procedure in which high energy from outside the body is focused on the stones to break them gradually. However, this procedure risks increasing the exposure dose of the patient's guardian or related workers.


Methods/Statistical analysis: In the extracorporeal shock wave lithotripsy laboratory and general fluoroscopy laboratory, an environmental glass dosimeter was installed at the same height as the X-ray tube on the radiation barrier, patient entrance, the staff entrance, and the patient view window to measure and analyze the cumulative dose for 3 months.


Findings: The cumulative 1 cm dose equivalent measured with the glass dosimeter for 3 months outside the barrier at the entrance and outside the barrier at the control room of the extracorporeal shock wave lithotripsy laboratory was measured to be less than the natural radiation dose. The cumulative 1cm dose equivalent value measured with the glass dosimeter for 3 months at the entrance of the control room of the extracorporeal shock wave lithotripsy laboratory was measured to be a maximum of 0.21mSv and an average of 0.07mSv. The cumulative 1cm dose equivalent measured with the glass dosimeter for 3 months at the entrance of the patient caregivers’ waiting room and the patient view window was measured to be less than the natural radiation dose. The cumulative 1 cm dose equivalent measured with the glass dosimeter for 3 months outside the barrier of the general fluoroscopic X-ray room was measured to be 0.86mSV, and the cumulative 1 cm dose equivalent for 3 months at outside the barrier of the control room was measured to be less than the natural radiation dose. The cumulative 1 cm dose equivalent measured with the glass dosimeter for 3 months at the entrance of the patient caregivers’ waiting room of the general fluoroscopic X-ray laboratory was measured to be an average of 3.41mSV, and the same at the control room's entrance was measured to be an average of 0.96mSv


Improvements/Applications: The results of this research is expected to be usefully utilized in the safe management of medical radiation. In addition, the measurement management of the leakage and scattered radiation for diagnosis requires continuous monitoring at the nation's dimension. Active support for research and development of the associated fields is deemed necessary.
