“This tutorial is for building an ionizing radiation detector with Arduino!
Hello! I decided to build this project because ionizing radiation can be dangerous, and it is very hard to know if it’s there. I am hoping this project will help people be able to create their own ionizing radiation detectors for relatively cheap!
How Ionizing Radiation Works
The definition of ionizing radiation is “radiation consisting of particles, X-rays, or gamma rays with sufficient energy to cause ionization in the medium through which it passes.” This includes air, water, and living tissue. Ionizing radiation can travel unseen and pass through these materials.

Hello! I decided to build this project because ionizing radiation can be dangerous, and it is very hard to know if it’s there. I am hoping this project will help people be able to create their own ionizing radiation detectors for relatively cheap!
How Ionizing Radiation Works
The definition of ionizing radiation is “radiation consisting of particles, X-rays, or gamma rays with sufficient energy to cause ionization in the medium through which it passes.” This includes air, water, and living tissue. Ionizing radiation can travel unseen and pass through these materials.
Ionizing radiation is on the right of the scale below:
A easily recognizable form of ionizing radiation today, is that of x-rays, which can penetrate our body and reveal pictures of our bones. Ionizing activity can alter molecules within the cells of our body. That action may cause eventual harm (such as cancer). Intense exposures to ionizing radiation may produce skin or tissue damage.
There are 5 types of ionizing radiation:
- alpha particles
- beta particles
- positrons
- gamma rays
- X-rays
Alpha particles are “positively charged particles consisting of two protons and two neutrons emitted from the nucleus of some radioactive atoms. An alpha particle is the nucleus of a helium atom. Unstable atoms with a low neutron-to-proton ratio may emit alpha particles.”(Osha)
Beta particles are “negatively-charged, fast-moving electrons emitted from the nucleus of various radionuclides. Unstable atoms with a high neutron-to-proton ratio emit negatively-charged beta particles.”(Osha)
Positrons are similar to Beta particles, but are positively charged. They are “positively-charged, fast-moving electrons emitted from the nucleus of certain radionuclides. Unstable atoms with a low neutron-to-proton ratio can emit positrons.”(Osha)
Gamma rays are “high-energy electromagnetic photons emitted from the nucleus of an unstable, excited atom. Gamma rays are pure energy and can travel great distances at high speed.”(Osha)
X-rays are “High-energy electromagnetic photons emitted from outside the nucleus. The primary difference between X-rays and gamma rays is that X-rays are emitted from processes outside the nucleus, but gamma rays originate inside the nucleus.”(Osha)
Ionizing radiation particles (e.g., alpha, beta) or high-energy photons (gamma rays, X-rays) can travel different distances and interact with the atoms of absorbing materials in their paths, causing excitation or ionization of the atoms. As shown in the graphic below, while alpha and beta particles are not very penetrating through other materials, gamma and X-rays are quite penetrating, as are neutrons. (Osha)
