ABSTRACT:
A method is provided for simplifying the calibration of neutron multiplicity counters. The method includes multiplicity counter dead time correction algorithms that preclude the need for extended calibration steps with known radiation sources. The algorithms include approximations that allow calculation of the counter's efficiency without knowledge of sample source activity or origin.
