Exposure to 26.5 GHz, 5G modulated and unmodulated signal, does not affect key cellular endpoints of human neuroblastoma cells

Abstract

Overview

The fifth generation (5G) network is currently being worldwide spread out, raising questions about its potential health impact. The current study aimed to investigate the effects of a 26.5 GHz 5G electromagnetic field on key cellular endpoints of human neuroblastoma cells.

Methodology

• A reverberation chamber-based exposure system was designed for the study.
• This system allowed the controlled exposure/sham exposure of cell cultures to both electromagnetic and biological parameters.
• The suitability of chambers was confirmed by evaluating cell proliferation and cell cycle progression.
• Exposure lasted 3 hours at a specific absorption rate of 1.25 W/kg, using both continuous wave and 5G modulated signals.
• Evaluations focused on cell cycle and DNA damage, including conditions with the oxidant menadione for possible cooperative effects.

Findings

• Results showed an absence of effects from exposures, both alone and in combination with menadione, when using continuous wave or modulated signals at the stated exposure level.

Conclusion

Further investigations are necessary, varying exposure and biological parameters, to strengthen the evidence regarding the absence of effects from 5G signals in the millimeter wave range. It is important to recognize that ongoing research continues to assess the potential health risks of electromagnetic field (EMF) exposure, and users should remain informed about possible links between EMF and health outcomes.
