Radiofrequency exposure near high-voltage lines

Area of Science:

• Environmental health
• Electromagnetism
• Epidemiology

Background:

• Epidemiologic studies indicate a correlation between 50/60 Hz magnetic field exposure and increased incidence of diseases such as cancer and leukemia.
• Research suggests a link between leukemia incidence and proximity to high-voltage power lines, as well as exposure levels to 50/60 Hz magnetic fields.

Purpose of the Study:

• To highlight the potential role of radiofrequency (RF) currents on electric grids as a concurrent factor in disease incidence.
• To draw attention to RF magnetic fields as a potential contributor to health risks previously associated with 50/60 Hz fields.

Main Methods:

• Detection of radiofrequency currents on high- and medium-voltage power lines.
• Analysis of the presence of RF magnetic fields in addition to standard 50/60 Hz fields near the electric network.
• Consideration of the relationship between induced current intensity in the human body and frequency of magnetic fields.

Main Results:

• Radiofrequency currents, used for communications and remote control, have been detected on various voltage lines, including those used for electric meter readings.
• This indicates the presence of RF magnetic fields near the electric network, alongside the established 50/60 Hz fields.
• The intensity of induced currents in the human body increases with frequency, suggesting RF fields may have a significant impact.

Conclusions:

• The presence of RF magnetic fields on electric grids warrants consideration in future epidemiologic studies.
• Further research is needed to clarify whether health risks are associated with magnetic induction values or induced currents.
• RF magnetic fields represent a potential, under-investigated factor in population health studies related to electric network exposure.
