放射性色层扫描仪是放射性色层分离中不可缺少的测量仪器,国外使用已近二十年,种类、型号很多,而我国至今未见有定型产品出售。为了满足我国放射性同位素及其标记化合物的研究、试制、生产和应用日益发展的需要,我们参照了国外样机及部分资料,并结合自己的经验,于1976年完成了设计,1977年由无锡医疗设备厂承担试制工作,并于1978年对样机进行了测试和改进,使产品基本定型。无锡市卫生局于1979年5月4日至8日在该市召开了鉴定会,认为其性能可靠,可以投入批量生产。图1为扫描仪全图。
The scanner equipped with scintillator is used for thin-layer or paper radiochromatogram scanning of ordinaty nuclides emitting
γ
and
β
rays
and also for
β
nuclides of lower energy
e. g.
14
C and
35
S. The accuracy of displacement of uniform motion is better than 100±1mm. Its performance and data give-out is comparable with that of similar type imported instruments.
This instrument can be used in quality control of radioisotope and labelled compound production
and in radiochemical
radiomedical
and radiobiological study.
