短寿命核素在核医学中的应用日益广泛。但过去传统标记方法都不够理想。国外近数年发展了电解标记法,具有标记率高,效果稳定,操作简便迅速等优点,对短寿命核素尤其适用。我们重复了国外实验,并在此基础上,根据实验结果和实际操作要求设计了这个仪器。一、仪器设计特点1.实验证明标记率主要由通过电解槽的电量决定。我们根据电流自动积分原理和分流方法,予先由旋钮置定所需要的电 Short-lived nuclides are increasingly used in nuclear medicine. However, the traditional methods of marking the past are not ideal. In recent years, the development of electrolytic markers in foreign countries, with a marked rate, the effect is stable, easy to operate quickly and so on, especially for short-lived nuclides. We repeated the foreign experiments, and on this basis, according to the experimental results and practical requirements of the design of the instrument. First, the design features of the instrument 1. Experimental proof Marking rate is mainly determined by the electricity through the cell. We based on the principle of automatic current integration and shunt method, the first set by the knob to the required electricity
