Ionizing radiation, an invisible and intangible enemy, exists not only in nuclear power plant reactors. In fact, we are bombarded by radiation from the surrounding environment and outer space all the time, and fortunately, our body is strong enough to resist the natural background radiation.

No active contact does not mean that high-energy ionizing radiation will not be encountered. Natural marble building materials, ore gems with different colors, and "negative ion powder" of unknown composition may contain different amounts of radioactive elements. With a Geiger counter, these radioactive sources have nowhere to hide.

Gravity: Geiger Counter Module Ionizing Radiation Detector

The Geiger counter can only detect ionizing radiation, such as nuclear radiation, X-rays, cosmic rays, etc. Electromagnetic radiation such as microwave oven radiation, mobile phone radiation, WiFi radiation, induction cooker radiation can not be detected.

In addition, the Geiger counter is a good random number generator, and undetermined high-energy particle ionization events can provide enough random entropy to get you a truly random number, rather than a fixed random sequence based on a random algorithm.


This product is not a professional measuring instrument and is only suitable for principle research and teaching demonstration. Not for use in radiation dose measurement that directly affects personal safety.

    1. Project: Making a Desktop Geiger Counter with Unihiker --- Real-Time Nuclear Radiation Monitoring

    Introduction: I had the idea to use a Unihiker to make a desktop Geiger counter. Basically, it's a device to detects the intensity of ionizing radiation. A typical Geiger counter has a sealed inflated tube and display that counts detected particles over time. I'll share how I DIY'ed the Geiger counter, to help with checking radiation levels in daily life.
