The influence of microwave radiation on the state of chromatin in human cells

TL;DR

This study investigates how 35 GHz microwave radiation affects human buccal epithelium cells, revealing chromatin condensation and membrane damage, with polarization influencing the extent of these effects.

Contribution

It provides new insights into the cellular effects of microwave radiation, highlighting polarization-dependent differences in chromatin and membrane responses.

Findings

Microwave radiation induces chromatin condensation.

Linearly polarized waves cause more membrane damage.

Left circular polarization has a lesser effect.

Abstract

Isolated human buccal epithelium cell were irradiated by microwaves at frequency f=35 GHz and surface power density E=30 mcW/cm2. The state of chromatin in human cells was determined by methodsof light and electron microscopy. The state of cell membranes was evaluated by the method of vital indigo carmine staining. The microwave-induced condensation of chromatin in human cells was revealed. Left side circulary polarized waves induced less effect than linearly polarized radiation. The linearly polarized electromagnetic waves induced cell membrane damage revealed by the increase of cell stainability. The data obtained are discussed in connection with the mechanisms of biologica effect of electromagnetic waves.
