What is the difference between ionizing radiation and electromagnetic radiation?
In physics, radiation is considered a process in which energetic particles or waves propagate in space. Due to the difference in energy of radiation itself, the reaction mechanism of its interaction with matter is also different. We often classify radiation into two types: ionizing radiation and non ionizing radiation. Usually, non ionizing radiation is also known as electromagnetic radiation.
Ionizing radiation is the radiation that ionizes matter when energy diffuses outward in the form of electromagnetic waves or particles and directly or indirectly interacts with it.
The main types of ionizing radiation include alpha rays, beta rays, X-rays, gamma rays, and neutron radiation. X-ray and gamma rays are electromagnetic waves, but due to their high energy, they have entered the category of ionizing radiation.
Ionizing radiation is divided into natural and artificial radiation.
Natural radiation refers to cosmic rays from outer space, as well as natural radioactivity present in the air, water, soil, rocks, food, and other natural environments.
Artificial radiation has been widely used in daily life, such as medical X-ray diagnosis, nuclear medicine, tumor radiotherapy, interventional radiology, and other radiation diagnosis and treatment applications; Non destructive testing such as nuclear power generation and industrial testing in industrial nuclear power plants, control of quality, density, moisture content, material level, and thickness in nuclear measurement systems, radioactive survey of geological and hydrological conditions such as oil logging, radiation processing, etc; Radiation modification, radiation breeding, radiation disinfection, radiation preservation and other radiation processing technologies in agriculture; Military nuclear weapons, submarines, etc.
Electromagnetic radiation is the phenomenon in which energy is emitted from a source into space in the form of electromagnetic waves and propagates in space. This type of radiation is generally generated by the movement of charges. Unlike ionizing radiation, electromagnetic radiation can actually be seen every day. For example, radio waves, microwaves, and infrared lamps all belong to electromagnetic radiation. In this regard, if properly utilized, electromagnetic radiation plays a very important role in our lives.
Protection against ionizing radiation: mainly by shortening exposure time, increasing distance from the source, using shielding materials to reduce exposure, and preventing inhalation and ingestion of radioactive substances. Different types of shielding materials and methods are used for different rays.
Electromagnetic radiation protection: Various household appliances, office equipment, mobile phones, etc. should be avoided from long-term operation as much as possible, and multiple household appliances should be used simultaneously as much as possible. Attention should be paid to leaving at least once an hour. In daily diet, one should eat more foods rich in vitamin A, C, and protein such as carrots, tomatoes, kelp, lean meat, and animal liver to enhance the body's ability to resist electromagnetic radiation.
