Abstract
In order to improve the detection efficiency and sensitivity of the detector for weak radioactive substances, a detector probe has been designed which with double photomultiplier & NaI (Tl), by using of multi pulse coincidence measurement and energy spectrum recognition algorithm to realize the fast detection of weak radioactive substances. Through the amplification factor, data calibration and detection threshold experimental research and data comparison found that, the detection efficiency and sensitivity of the detector for weak radioactive substances are improved, this also proves the effectiveness of the design of detection probe.
