Assessment of the potential threats to brain health posed by the radiation from 5G sub-6 GHz base stations in China using dosimetric methods

Abstract

Overview

The 5G sub-6 GHz radio frequency (RF) electromagnetic fields (EMF) are extensively utilized in China's telecommunications. Public concerns are increasing regarding the potential brain health impacts of the higher frequency bands in 5G, especially when compared to earlier 2G, 3G, and 4G technologies. A scientific approach is crucial to evaluate the potential health hazards posed by these novel frequency bands in 5G communication technologies.

Methodology

This study applied dosimetric methods to evaluate the brain tissue dose response from the sub-6 GHz band EMF emitted by base stations. Employing a 3D virtual human body model, researchers established a simulation environment to measure specific absorption rate (SAR) and internal electric field (IEF) values across different bands. The measurements were normalized against exposure limits to ensure accuracy.

Findings

The findings suggest that the high-frequency sub-6 GHz band of 5G is associated with the lowest dose values among the studied bands, indicating a reduced health threat to the brain compared to lower frequency EMFs. The study also adhered to both the ICNIRP guidelines and Chinese national standards, providing a robust evaluation of EMF exposure risks.

Conclusion

The research confirms a lower risk of brain health issues with the use of sub-6 GHz high-frequency band in 5G technologies. This supports the ongoing adoption and safety of 5G networks in China and potentially other regions. Potential limitations include the variability in industry standards and the exclusion of real-world measurement data in the modeled scenarios. Future research is encouraged to integrate epidemiological methods with these findings to further understand the implications of EMF exposure on brain health.
