Build a Simple ION Chamber to detect the Apha Particles. You could mount your Geiger Tube in a wand connected to the PCB via some Coaxial Cable.

Lovely informative video's hope to see that follow-up. I've bought the same module and am therefore quite curious how it holds up compared to a calibrated one.

Thanks! I have compared it to a Gamma Scout costing around €400 and it was in general agreement. You can see the Gamma scout on this link: www.gamma-scout.com/EN/Leistungsmerkmale.php I had some problems with my camera doing the video but hope to salvage what I can and upload it soon.

Nice, thank you. The uSv/h reading arguably has too many digits. When the CPM is "30", then the uSv/h is "0.2436" which is overly precise considering that the input data is just 30. It's a "Significant Figures" detail.

one thing though, do you need a window on the box for better sensitivity or how do you calibrate for pvc enclosure for beta and gamma?

Plastic will not stop beta or gamma particles. In my testing there was no difference in it's performance in or out of the enclosure. www.cooking-hacks.com/documentation/tutorials/geiger-counter-radiation-sensor-board-arduino-raspberry-pi-tutorial/#types_of_radiation

Hi, recently I have done some projects using "LoRa" modules to send data (temperature readings) to remote Receivers. That may give you some ideas : kzread.info/dash/bejne/ZIVosZpxmNDQqqg.html Also see : kzread.info/dash/bejne/l6iu0JSleai1iJc.html

Gave this project a build but with a I2C OLED display. Looks nice, but its a smaller than the LCD so a more difficult read. So now once I move it to a nano and then 3d print a case, it should be good to go. Any idea how to calibrate the geiger board? I have access to a radiation meter (as im a radiation worker) so getting accurate numbers is easy for me. However this geiger kit has surprisingly little data online. I'm guessing the trim pot on the board is for calibrating the count rate?

DO NOT TOUCH THE TRIM POT!! It sets the high voltage for the Geiger tube! You can see the schematic here : drive.google.com/file/d/1l8TuQgZiDeYuhiSFNRPBbLaZncGen0ZS/view?usp=sharing Calibration is done in software by changing the conversion factor : kzread.info/dash/bejne/dYSLmaWLda7RddI.html Please consider subscribing if you have not done so already!

The glass beads only contain a miniscule amount of Uranium oxide ay 0.2%. I cannot see that being a problem. When I was at school and my physics teacher was demonstrating radiation with some samples (lead apron and everything) he asked if anyone had a watch with a luminous dial. My friend had his father's watch from his time in the air force. When tested the counter went off the scale!! Way more dangerous than the samples!
