New Research Examines Terahertz Radiation Effects on Human Cells

A recent scientific review published in Frontiers of Optoelectronics has compiled modern research on how terahertz (THz) electromagnetic radiation affects both normal and cancer cells. The study examines radiation in the frequency range of 0.5-100 THz at various power levels and exposure times.

The research highlights that THz radiation is particularly well absorbed by water, which comprises 30-90% of living tissues and cells. Scientists now widely accept that THz radiation can affect biological cells and living organisms, though the exact mechanisms are still being studied.

Understanding the Biological Impact

According to the paper, radiation in and near the terahertz range (0.1 to 100 THz) can interact with biological molecules through various mechanisms. These interactions may affect the vibrational and rotational movements of molecules, potentially leading to local temperature changes in cellular environments, alterations in ion channel activity, and changes in transmembrane capacitive charge.

The review also addresses safety concerns regarding THz radiation exposure to the human body, examining its effects on biological cell structures and systems. Additionally, researchers are exploring the use of THz spectroscopy as a monitoring tool, with particular interest in using interstitial water spectra as potential markers for pathological processes.

While the research provides important insights into THz radiation's biological effects, the study emphasizes that investigations are ongoing, particularly regarding non-thermal effects at low power density levels.
