Researchers from the Korea Advanced Institute of Science and Technology (KAIST) announced findings from a research project that exposure to terahertz radiation on an animal showed signs of infections on skin tissue. Previously, terahertz radiation was thought to be harmless to humans, because of its low energy and wider applications than x-radiation.
To test the effects of terahertz radiation, the team developed a high-power terahertz generator and a high resolution 3D laser scanning microscope. A genetically-engineered mouse was exposed to high-terahertz radiation for 30 minutes, and the skin of the mouse was monitored with the microscope. The team found that the number of infected cells increased more than six times after six hours of exposure.
