Dosimeter Geocaching

Dosimeter Geocaching is a hot-and-cold geocaching game that uses a Geiger‑Müller dosimeter to locate hidden radiation sources. Each day targets move and vary in strength, making every outing a new challenge. The device shows radiation levels and uses red and blue LEDs—red flashes as you approach, blue flashes as you move away—to guide your search.

Perfect for short walks in parks or small trips, the game blends outdoor exploration, puzzle-solving, and hands-on hardware interaction. Play solo or with friends, track changing locations, and sharpen your navigation skills. Always follow local safety rules and avoid handling or disturbing suspicious sources.
