Will guide you to build a Radiation mapper device with DFRobot Beetle ESP32 C3 and Geiger Counter.
Collate weight, color, and emitted ionizing radiation of foods to train a NN. Then, run it on Beetle C3 to detect food irradiation doses.
I built a desktop radiation monitor based on a cheaply available board, added some toggle switches, Nixie tubes and a Raspberry Pi.
