A method for improvement of signal-to-background ratio of airborne scintillation gamma-detector

N. N. Krupa, O. N. Partala, V. A. Tarasov


The paper describes a new method for improving sensitivity of scintillation-type gamma-detectors, whose pickup elements include a measuring crystal and a protective alkali-halogen one with different times of gamma-luminescence relaxation. Processing of the luminescence signal after photoelectric multiplier is performed by a magnetoacoustic correlator with memory or differentiating devices.
