DIY desktop level Geiger counter to detect nuclear radiation intensity in real time!

At present, radiation monitoring is closely related to us. It is not only related to our health and safety, but also hides many mysterious and fascinating scientific phenomena. Nuclear radiation is the release of particles or electromagnetic waves from radioactive substances. It is divided into three kinds: alpha radiation, beta radiation and gamma radiation.

These radiations are closely related to our daily learning and living,digital nitrate tester such as in medical diagnosis, energy development and production and food irradiation. However, they also pose certain dangers. Understanding the characteristics and safety thresholds of these radiations can help us to be better prepared for potential risks.

Grab the space next to you and create a desktop Geiger counter. In short,radiation detectors this is a special counting instrument that detects the intensity of ionizing radiation.

Usually a Geiger counter consists of an inflatable sealed tube and an information display that measures the number of rays per unit of time. Below I am going to share in detail the various aspects of making your own Geiger counter to help us monitor radiation values on a daily basis and add customization.

How to measure the radiation value?

A Geiger counter is a gas discharge detector filled with a gas that is easily ionized.geiger counter handheld When radiation enters the tube, it causes the gas to ionize, generating pulses of electricity. These pulses are amplified and turned into counting pulses. We only need to count the number of pulses per unit of time to directly calculate the amount of ambient radiation. The biggest advantage of Geiger counters over other detectors is the output of digital electrical signals, which allows accurate counting of radiation without the need for complex analog circuits. So we can calculate how many particles pass through the gas tube per minute, and then we can calculate the current radiation level in the environment.

It is very convenient to monitor the radiation level in the environment in real time by using a DIY-made tabletop Geiger counter. It has the advantages of being simple to make, easy to use and low cost. The radiation dose rate can be calculated by simple pulse counting, which helps us to understand the radiation situation around us in real time. Meanwhile, the blank board used in the project not only has a touchable screen, but also can be connected to other hardware sensors. The direct use of python programming also greatly increases the flexibility of creation. This homemade device is much more flexible and customizable than the usual commercial detection devices. We can add alarm functions and data logging functions to make radiation detection more intelligent. In conclusion, at a time when nuclear contamination is becoming more and more familiar, making a desktop version of Geiger counter to make radiation monitoring within reach not only raises awareness of radiation safety, but is also a meaningful creation.
