Abstract

Overview

This paper investigates the exposure levels of electromagnetic fields (EMF) on honey bees, focusing on radio frequencies from 2.5 GHz to 100 GHz. The research utilizes numerical simulations to derive data.

Methodology

  • Approach: Finite-difference time-domain (FDTD) technique.
  • Tools: Sim4Life EM-FDTD solver for simulations.
  • Model: Honey bee modeled as a 3-tissue heterogeneous dielectric object.

Findings

The study determined the Specific Absorption Rate (SAR) in honey bee tissues, which helps in predicting potential adverse effects due to EMF absorption. Key results include:

  • SAR values for whole-body and brain tissue.
  • Values normalized for incident plane-wave power density of 1 mW/cm2.
  • Dependence of EMF absorption on E-field polarization, frequency, and anatomical features of the honey bee.

Conclusion

The findings indicate a significant absorption of EMF energy in insects, which could imply potential health risks for honey bees due to EMF exposure across diverse frequencies.
