초록
In this study, a foods radioactivity monitoring sensor was developed as a part of basic research for household radioactivity monitoring, and its performance was evaluated using a calibration source. The prototype of the sensor was based on a CsI:Tl scintillator using a crys- tal light guide and Si photomultiplier. The light guide was introduced to improve gamma-ray detection efficiency. For quantitative eval- uation, tests were conducted using 134Cs liquid source. In the performance evaluation, It was confirmed that analysis of 134Cs: 100 Bq/L(kg) was possible. Thus, result of this study is expected to contribute to research in the development of the household foods radio- activity monitoring system
