Magnetite Particle Presence in the Human Brain: A Computational Dosimetric Study to Emphasize the Need of a Complete Assessment of the Electromagnetic Power Deposition at 3.5 GHz

Abstract

Overview

The increasing presence of magnetite nanoparticles in the human brain, derived from both internal and external sources, underscores the critical need for comprehensive assessments of electromagnetic power deposition, especially at frequencies typical of consumer electronic devices.

Findings

• Commonly used dosimetric numerical codes fail to precisely account for magnetic losses at these frequencies, raising concerns over their accuracy.
• The difficulty stems from inadequate algorithms to process magneto-dielectric substances involving complex equations and considerations like eddy currents and properties of magnetite particles.
• Studies utilizing existing commercial software provide initial insights but are deemed unreliable for calculating total power absorption in brain models with ferrimagnetic content at 3.5 GHz EM waves.

Conclusion

It's imperative to develop more accurate computational tools that take into account the specific complexities of magnetic losses in brain tissues exposed to high-frequency electromagnetic fields. This would enable better understanding and mitigation of potential health risks linked to electromagnetic radiation exposure.
