放射性β源的信号模拟与测量

Simulation and Measurement of Signal of p Radioactive Resource

过去沾染检查训练采用β放射源。为避免放射源对人体的危害和对环境的污染,可采用模拟信号代替放射源。模拟信号要具有随机性和距离效应,通过辐射线圈以磁场形式向外辐射,再通过探测线圈接收,从而实现模拟测量的目的。

In the past the β radioactive resource was used in radiactive contamination detection training. In order to avoid the harm of the radioactive resource to human body and to our environment, we can use simulated signal instead of radioactive resource. The simulatet signal must have randomicity and distance effect. Through a radiant loop sending out electromagnetic wave and another detective loop receives the electromagnetic wave, the aim of simulated measurement can be realized.
