    This study presents a new method to correct for crosstalk in nuclear counters. The technique successfully calibrates multidetector gamma counters for improved accuracy with gamma emitters.

    Area of Science:

    • Nuclear instrumentation
    • Radiation detection and measurement

    Background:

    • Crosstalk in multidetector systems can lead to inaccurate count rates.
    • Accurate gamma counting is crucial for various scientific applications.

    Purpose of the Study:

    • To develop and validate a method for compensating crosstalk in nuclear counters.
    • To apply this method to a multidetector gamma counter system.

    Main Methods:

    • A standardization procedure was developed to measure relative detector efficiencies.
    • Measurements included sample presence within each detector and in all other detectors.
    • Calibration data was stored for subsequent correction.

    Main Results:

    • The method successfully corrected observed count rates for crosstalk.
