20 ºó CYLINDRICAL BOTTLE FOR GAMMA-RAY SPECTROMETRY WITH GE-DETECTOR

摘要

The subject innovation relates to a standard container for the radionuclide and the radioactivity measured in the radioactive waste as germanium (Ge) semiconductor detector.; Common conventional containers (diameter 22.5 mm, height 57.5 mm) is easily handled by conducting an unstable form of a small diameter, a high altitude there is a fear of losing or contaminating the detector samples a low detection efficiency. In addition, it is not standardized, without the container thickness, the type, volume, etc. are different, the measurement at each geometry vary the accuracy of the measurement because the low and difficult to appropriate amount of injection when the maximum capacity volume of the sample injected as a 20 mL easily overflow not only difficult to handle material as radioactive waste after use, as the glass is processed with such volume gamyong, scrap it is difficult.; Standard vessel of the subject innovation, unlike the manufacturing method configured by using a polypropylene material as a sample container main body, the outside lid and in the lid, and the detection efficiency is optimized through testing of aberration standard container (diameter 49.9 mm, height 48.6 mm) a larger volume (95 mL) and was always normalized to have a certain size and thickness and shape improves the measurement accuracy by minimizing the absorption of the sample container surface smoother surface.
