The detector efficiency should be specified according to both criteria. For example, the conventional format used for gamma-ray … Webgoal is to determine how efficient our gamma detector is. The absolute peak efficiencies of the detectors were previously determined by the efficiency-ratio method using an uncalibrated 152Eu source and calibrated 137Cs, 60Co, and 133Ba sources at 14 cm. My job is to update this information using the same techniques.
