Abstract

Appropriateness of representation of a biological object surface as an equipotential surface has been proved for conditions of a quasistatic exposure to EMF of frequencies lower than 1 MHz. The conditions, at which a self capacitance of a biological object is its basic electrical parameter, have been considered. A factor of animal-to-human approximation of low-frequency EMF exposure conditions was estimated on the basis of equal dose loading in biological objects of different geometric sizes.

Main findings

For quasistatic EMF exposure at frequencies below 1 MHz, representing a biological object surface as an equipotential surface was supported. The paper considers conditions where self-capacitance is the main electrical parameter and estimates an animal-to-human approximation factor based on equal dose loading for objects of different sizes.

Outcomes measured

  • Validity of representing biological object surface as equipotential under quasistatic EMF exposure <1 MHz
  • Conditions where self-capacitance is the basic electrical parameter
  • Animal-to-human approximation factor based on equal dose loading across different geometric sizes

Limitations

  • No specific exposure source described
  • No health or biological effect outcomes reported in the abstract
  • No quantitative results or numerical approximation factors provided in the abstract
  • Population/species and experimental details not stated
