A hot and cold game that is used to find radiation sources in your area. A Geiger-Müller counter (dosimeter) is used to show the degree of radiation.
The aim of the game is to find a source of radiation of different strength. The stronger the source, the more remote it is probably. Every day, resources change their location, so every day is a new challenge and you can find them in other places.
The game is suitable for short walks in the park or for smaller trips.
Use the red and blue LEDs to guide you to different places in your area. Flashing of the red LED means that you are approaching the target, while flashing of the blue LED means that you are moving away from the target.
