چکیده انگلیسی
A scintillating fiber array detector for measuring gross beta counting is developed to monitor the real-time radioactivity in drinking water. The detector, placed in a stainless-steel tank, consists of 1096 scintillating fibers, both sides of which are connected to a photomultiplier tube. The detector parameters, including working voltage, background counting rate and stability, are tested, and the detection efficiency is calibrated using standard potassium chloride solution. Water samples are measured with the detector and the results are compared with those by evaporation method. The results show consistency with those by evaporation method. The background counting rate of the detector is 38.131â¯Â±â¯0.005â¯cps, and the detection efficiency for β particles is 0.37â¯Â±â¯0.01â¯cps/(Bq/l). The MDAC of this system can be less than 1.0â¯Bq/l for β particles in 120â¯min without pre-concentration.
