Right, i will try to put the worms back to the can, haha. but still i will put more effort on this one. thanks for your advice :)

So here is my detector, i build it with Aluminum and Copper as the anode wire. i use the darlington pair circuitry for current gain, bc547 NPN transistor and bc557 PNP Transistor .

i did, and now not even a single thing was detected.

i haven't tried to check the sources, i will consult it with my teacher later. Any idea how to block those stray electric fields?

i connect the cathode plate to the circuitry as i mentioned above, or should i parallel another single wire directly to the ground?

i am using Americium 241 and Ra226, so far my detector can detect the americium, but got zero results for Ra226. like i said there is still some error when i approach my hand close to detector, the led lights. so I'm not really sure, whether the LED lights because of radiation or the energy from...

Thank you for your response, yes i noticed that the current caused by ionization is very low, so I'm using the darlington pair. i follow this circuitry which i got from techlib.com . i'm using the bc547 as the npn transistor and bc557 as the pnp transistor. another problem occur, now that my...

Thanks for your response, but i tend to build an ion chamber without using the GM tube, what i intend to is to do something, like i found from the techlib.com site, where an ion chamber emits light when being approached to radioactive radiation. here is the link...

Hi I'm a student working on my last assignment in physics department. now I'm trying to make a radioactive radiation detector with the principle of ion chamber. i want to add some new mechanism which when a charged particle pass through the chamber, an LED would emit a light. is there any...
