So, I'm working on a radiation detector for a science project. I have a small pcb that outputs clicks from the radiation detected, its powered my a 9v battery. My idea was that I could hook up the output of the radiation detector to the microphone port of my laptop but I'm unsure if the 9v signal will fry it

Would this work or do i need to limit the voltage somehow?

I didn't find the right solution
