Abstract

In order to calibrate the CR-39 Solid State Nuclear Track Detector (SSNTD), a closed -circulation type SSNTD-Calibration-System containing a radon-cup with the Millipore filter has been set-up, and the tracks produced on the SSNTD were measured for the known amount of radon concentration. Calibration factor for the time integrated radon concentration as a function of the track density on CR-39 was estimated to be $0.24{\pm}0.09(pCi/l)\;day/(Tr/cm^2)$.

CR-39 고체비적검출기를 교정하기 위하여 밀봉 순환 방식의 고체비적검출기 교정 장치와 밀리포어필터가 부착된 라돈컵을 제작한 후 기지의 라돈농도에 대한 비적 수를 측정하였다. 그 결과 CR-39 고체비적검출기의 단위 면적당 생성된 비적 수에 대한 시간 적분 라돈 농도는 $0.24{\pm}0.09(pCi/l){\cdot}day/(Tr/cm^2)$ 였다.
