~(99)Mo-~(99m)Tc放射性同位素生产自动控制与监测系统系为我院同位素研究所的生产线而开发研制的。自动定量分装体积为0.5—10 ml的放射性溶液(间隔0.5 ml,共20个量程),溶液强度为12—740×10~9Bq。对生产工艺流程中的七套上柱设备进行实时控制,包括发生器的运行操作,上柱、淋洗及吹干等定时操作,最后送入传送带,共计70—80控制点。同时要求γ谱仪系统监测表面污染及分装质量,在强本底下定量测定
The automatic control and monitoring system of ~ (99) Mo- ~ (99m) Tc radioisotope production has been developed for the production line of our institute isotope institute. Automatically quantify the volume of 0.5-10 ml radioactive solution (0.5 ml interval, a total of 20 ranges), the solution strength of 12-740 × 10 ~ 9Bq. Real-time control of seven sets of equipment on the production process, including the operation of the generator, timing operation on the column, washing and drying, and finally into the conveyor belt, a total of 70-80 control points. At the same time, the gamma spectrometer system is required to monitor the surface contamination and the quality of the aliquotings. Quantitative determination
