What Is the Difference Between Ionizing and Non-Ionizing Radiation?
Non-ionizing radiation refers to radiation that has relatively low energy and does not cause ionization of material atoms or molecules. Non-ionizing radiation includes low-energy electromagnetic radiation. There are ultraviolet, light, infrared, microwave and radio waves. Their energy is not high, and only the particles in the material will vibrate and the temperature will rise.

Definition of non-ionizing radiation
- Non-ionizing radiation has less energy than ionizing radiation. Non-ionizing radiation does not ionize matter, but changes the molecular, atomic rotation, vibration, or valence electron orbital states. The effects of non-ionizing radiation on living tissue; different non-ionizing radiation can produce different biological effects.
- Ionizing radiation refers to all radiation that can cause ionization of matter. Including alpha rays, beta rays, gamma rays, X-rays, neutron rays, etc., such as level gauges for production level measurement, X-ray flaw detection and thickness gauges, neutron rays for moisture measurement, and medical applications X-ray diagnostic machines, gamma-ray therapy machines, radioisotope reagents for nuclear medicine, etc.
- According to whether the radiation particles can cause the ionization of the propagation medium, the radiation is divided into two categories: ionizing radiation and non-ionizing radiation. In fact, electromagnetic radiation is just an electromagnetic wave. We often say that non-ionizing electromagnetic waves refer to electromagnetic waves in the radio frequency and microwave bands with a frequency of 30 to 3000 MHz. Because the energy of their photons is not enough to ionize neutral molecules and atoms, they are called non-ionizing.

- The ionizing radiation acting on the human body is classified into natural radiation and artificial radiation. Since ancient times, human beings have been exposed to various types of ionizing radiation that naturally exist. Generally, these natural radiation sources are called natural background radiation. The background radiation mainly comes from cosmic rays, radionuclides of the earth itself, and radionuclides produced by the interaction of cosmic rays with atomic nuclei in the atmosphere. These radionuclides can cause exposure to the human body from the outside, or they can be caused by inhalation or ingestion into the body due to the inclusion of these radionuclides in air, water, and food. Inhalation is currently considered the most important route, followed by external exposure and ingestion. In addition to natural radiation, humans are often exposed to various artificial radiations. The main artificial radiation sources include: nuclear explosions, radiation sources generated during the production of nuclear energy, medical exposures, and radiation sources used in consumer products.
