Influence of detector resolution on the occurrence of false alarms of radioactive wastewater monitors

This paper deals with the analysis of the influence of detector resolution on the occurrence of unwanted false alarms caused by natural radiation. A comparison of two compatible scintillation detectors with the same size: 2″×2″ NaI (Tl) and 2″×2″ LaBr3(Ce) is given. The main difference between the d...

Description
Summary:This paper deals with the analysis of the influence of detector resolution on the occurrence of unwanted false alarms caused by natural radiation. A comparison of two compatible scintillation detectors with the same size: 2″×2″ NaI (Tl) and 2″×2″ LaBr3(Ce) is given. The main difference between the detectors is in the resolution, which is about 3 times better for LaBr3(Ce). The work demonstrates a significant impact of using a spectrometric mode of analyzer linked with a good resolution detector. In conclusion a particular analysis of the natural Bi-214 signal proportion in the Cs-137 discriminator windows shows negligible amount of crosstalk for detector resolution below 3.5%.
