摘要
介绍了在光谱模式下利用带有 "SpDec "软件的 a§b-辐射计 UMF-2000 的经验。a 发射体（18 种同位素）的能量校准曲线显示出良好的线性近似，而 b 发射体（8 种同位素）的类似能量校准曲线显示出不良的线性近似。说明了由于光谱能量分辨率低、源的氡同位素发射和源厚度不同而导致的 a 发射体识别方面的一些局限性。使用两个铀含量较高的天然水样本对该装置进行了测试。
About the Possibilities of Using Alpha Beta Radiometer UMF-2000 with «SpDec» Software for Spectrometric Measurements
The experience of exploitation of a a§b-radiometer UMF−2000 with «SpDec» software in spectrometric mode was described. Good linear approximation was shown for energ calibration curve for a-emitters (18 isotopes), whereas the similar energy calibration curve for bemitters (8 isotopes) showed bad linear approximation. Some limitations in identification of a-emitters due to low energy resolution of spectra, emanation of radon isotopes from sources and difference in source thickness were described. The device was tested using two samples of natural water with a high uranium content.
