Abstract
An in situ detection method for beta-ray distribution was developed. The method uses the gamma-ray sensitivity difference between two scintillators: a cadmium-tungstate (CdWO4) scintillator and a plastic scintillator. The gamma-ray sensitivity ratios for several gamma-ray sources such as Cs-137, Co-60, Na-22, and Mn-54 were experimentally characterized. The sensitivity ratio for Cs-137 between the CdWO4 and plastic scintillators was 8 +/- 0.32, while the sensitivity ratio for beta rays from Sr-90 was 1.03 +/- 0.006. The beta-ray contributions to the total counts can be evaluated using this characteristic. A combined beta-ray and gamma-ray source was prepared, and its beta-ray distribution was successfully obtained using the proposed method.
