초록
A dosimeter using tissue-equivalent scintillator by photon-counting method was developed and evaluated in its performance. Thedosimeter is portable and can be operated by low power from lap-top computer. A data-acquisition software of the dosimeter system was developed by Labwindows/CVI based on Windows. The energy to channel ratio for energy calibration was 0.839 keV/ch. obtained from pulse height spectrum of 137Cs and 60Co gamma-ray. Using the dosimeter system, the absorbed dose of environmental radiation in Gyungju was 0.18 μ㏜/h.
