Nuclear radiation sensor with photodiode as a detector. Photodiode doesn't require high voltages as GM tubes do. Smaller size makes better resolution. Side effect is electronic must be more sensitive.

There are many ways to measure radioactivity level, semiconductor detectors sense interactions between ionizing radiation and p-n junction. Because in hobbyist area most popular are Geiger-Muller based detectors (in short: not a semiconductor but lamp based devices), I think it's a cool idea to take a look at this approach.
HardwareDataLogger is a simple pulse counter based on NUCLEO-F091RC with additional shield (for real-time data display using LCD).
PCB project was done in KiCAD.
