Abstract

Overview

Marine radars are significant sources of electromagnetic pollution during navigation and anchor watchkeeping. This study specifically focuses on the electromagnetic fields emitted from marine radars on ships of different tonnage and types to assess the extent and impact of electromagnetic pollution.

Methodology

  • Employed a SRM 3006 compact spectrum analyzer operated within the 400 MHz–6 GHz frequency range.
  • Used a triaxial antenna for measurements.
  • Compared results with ICNIRP (International Committee on Non-Ionizing Radiation Protection) benchmarks.

Findings

The collected data indicated that electromagnetic pollution levels from radar antennas generally surpassed ICNIRP limits, suggesting a high potential for adverse health outcomes due to prolonged crew exposure to magnetic field pollution.

Conclusion

Potential future steps include conducting more comprehensive studies involving larger samples and continuous measurements. The findings underline the urgency to consider revising maritime regulations and enhancing industry standards to mitigate electromagnetic pollution.
