Abstract

Overview

We investigated the impact of continuous terahertz (THz) radiation on a rat glial cell line, focusing on cytotoxic effects related to exposure duration and power density.

Findings

• Exposure of rat glial cells to THz radiation ranging from 0.12 to 0.18 THz with an average power density of 3.2 mW/cm² showed a dose-dependent increase in apoptotic cells.
• Relative number of apoptotic cells increased by 1.5 times after 1 minute and doubled after 3 minutes of exposure.
• These results support concerns about the biological hazards of intense THz radiation.

Conclusion

Findings from this study underline the potential biological hazards of THz radiation, suggesting limitations in diagnostic applications of THz technology due to concerns over power density and exposure duration.
