便携式背散射检测仪样机设计

Prototype Design of a Portable Back-scattering Detector

设计了一种便携式背散射检测仪,使用低活度133Ba作为射线源,以低功耗单片机MSP430F449为智能仪表核心。使用所设计的检测仪样机测量分别装有水和汽油的塑料瓶时,其计数有明显差异。该检测仪有望用于公共安全领域的反恐和边境、口岸的反走私工作。

A back-scatter portable detector is designed. In the design, 133Ba is used as the radiation source and a low power MCU, MSP430F449 is the CPU of the measuring electronics. Two bottles filling up with water and gasoline respectively can be distinguished by a prototype of the detector. The possible application of the detector is in public security sector, and the detector can be used as a facility in antiterrorism and anti-smuggling.
