Benefits of Terahertz Radiation: Modern Technologies for Health and Safety
Terahertz (THz) radiation consists of high-frequency electromagnetic waves that occupy an intermediate position between infrared radiation and microwaves. The wavelength of THz radiation ranges from 1 mm to 0.1 mm, making it a unique tool across various scientific and technological fields. One of the key advantages of THz radiation is its ability to impact human body cells, activating them and enhancing overall life processes.
The human body can both absorb and emit THz waves. THz radiation exposure helps deliver a high concentration of anions (negatively charged ions) to cells, reducing the accumulation of excess positive ions. This process revitalizes and “recharges” cells, accelerating metabolism and increasing body temperature. As a result, it improves the body’s overall condition and speeds up recovery processes.
Free radicals are molecules with unpaired electrons that can damage cells and contribute to various diseases. THz radiation is absorbed by free radicals, causing them to heat up and break down. Destroying free radicals eliminates associated negative factors, promoting recovery and well-being.
THz radiation is safe for humans. It is emitted by all physical objects with a temperature above 10 degrees Celsius, with an energy level that is only 1/40th that of sunlight. Due to its unique properties, THz radiation has found widespread application in medicine, security, and other fields.
Terahertz waves can be used for non-invasive medical examinations and diagnostics. THz devices can detect hidden health issues, such as tumors and inflammation, without the harmful effects of ionizing radiation.
THz radiation is widely used in security screening at airports, train stations, and other high-traffic areas. In 2014, China developed and tested the first THz security inspection device, breaking the monopoly of European and American technologies. These devices can detect hidden items, such as lighters and drugs, without harmful effects on the human body.
THz radiation has been recognized as one of the “Top Ten Technologies Changing the Future World” by the U.S. government. Countries like Germany, Switzerland, Russia, Japan, and South Korea actively research and develop technologies related to THz radiation. In 2005, China organized the “Xiangshan Science Conference” to discuss THz technology development and establish a national plan for advancing this field. In 2007, research on THz radiation was included in China’s primary fundamental research development plan.
Terahertz radiation serves as a powerful tool for cell activation, metabolism improvement, and free radical reduction. Its safety and efficacy make THz technologies promising for applications in medicine, security, and other fields. International recognition and active research in this area underscore the importance of THz radiation for the future development of science and technology.
