How To Make Radiation Detector Circuit
In this Article and video the students of electronics will learn how to make a radiation detector circuit. It is a easy electronics DIY project which you can easily make at home. This circuit is very useful to detect mobile radiation. In this circuit using LM 358 IC, BC 547 Transistor and some supporting components. I will show you the complete process of making Radiation Detector Circuit step by step.

This circuit does not really detect radiation ad such. But radiation by radio wave lenghts.
The LM358 you use , which is a dual op-amp.
By using a small wire as an antenna , the LM358 amplifies this small signal so that it can then pass to Q1 BC547 , a general purpose transistor which then buzzes a buzzr
