A NOVEL AUTO CALIBRATION TECHNIQUE FOR RADIATION DETECTORS

摘要

An apparatus and a method for calibrating a source detection device. The apparatus comprises a detector having a known amplification gain, a count rate meter, a means of measuring peak energy of a detected particle, a means of counting the number of particles detected at a given energy range and a means of comparing the number of particles counted over an energy range with an expected value. The apparatus adjusts the gain to cause the measured spectrum to correspond with an expected spectrum.
