Abstract

Overview

There are growing concerns surrounding the extended exposure to weak radiofrequency (RF) fields and their potential adverse health effects. This study focuses on HT-1080 fibrosarcoma cells and the effects of simultaneous exposure to static and RF magnetic fields.

Findings

• Exposures involved static magnetic flux densities ranging from 10 μT to 300 μT and RF fields with amplitudes from 1 nT to 1.5 μT over a frequency range of 1.8 to 7.2 MHz, sustained over four days.
• Various cellular parameters such as cell growth rates, intracellular pH, hydrogen peroxide, peroxynitrite, membrane potential, and mitochondrial calcium were assessed to determine changes.
• Results indicated dependencies on carrier frequency, the magnitude of RF magnetic fields, modulation frequencies, and background static magnetic field (SMF).

Conclusion

The alterations observed in this cell study suggest connections to important physiological disruptions linked to diseases including cancer and Alzheimer’s. These effects might be mediated via hyperfine couplings between electrons and nuclear spins, thereby influencing reactive oxygen and nitrogen species (ROS and RNS) levels. These findings underscore potential risks and emphasize the critical importance of managing external magnetic fields in various health-related scenarios.
