Terahertz radiation showed no genetic damage to human blood cells in this preliminary study.
Plain English Summary
Summary written for general audiences
Italian researchers exposed human blood cells to terahertz (THz) radiation at frequencies of 120-130 GHz for 20 minutes to test for genetic damage. They found no chromosomal damage or DNA breaks at any of the power levels tested, suggesting THz radiation may not cause immediate genetic harm to blood cells.

}Quick Questions About This Study
No, this study found no chromosomal damage or DNA breaks in human blood cells exposed to 120 GHz terahertz radiation for 20 minutes at 0.4 mW/g power levels.
Researchers tested 130 GHz radiation at three different power levels (0.24, 1.4, and 2 mW/g) and found no genetic damage or cell cycle disruption in human blood samples.
Human blood samples were exposed to terahertz radiation for exactly 20 minutes in laboratory conditions to test for potential genetic damage using specialized cell analysis techniques.
Scientists used the cytokinesis block micronucleus technique to check for chromosomal damage and the alkaline comet assay to detect DNA breaks in blood cells.
Yes, the researchers noted this was the first study specifically designed to evaluate whether terahertz radiation could cause genetic damage in human cells.
