RADIATION DETECTOR ASSEMBLY AND SAMPLE ANALYZER

摘要

Disclosed is a radiation detector assembly which can easily make a decision as to whether an energy calibration is needed. The radiation detector assembly detects radiations, creates pulse signals having pulse heights corresponding to the energies of the radiations, converts the pulse heights of the pulse signals into energies, and creates a radiation spectrum. The radiation detector assembly includes a qualitative analysis portion for assigning peaks appearing in the radiation spectrum, a conversion value calculating portion for calculating energy conversion values for converting the pulse heights into the radiation energies based on the assigned peaks, and an energy calibration decision portion for making a decision as to whether an energy calibration is needed, based on the calculated energy conversion values.
