Radio Hazard Safety Assessment for Marine Ship Transmitters: Measurements Using a New Data Collection Method and Comparison with ICNIRP and ARPANSA Limits.

View Original AbstractMarine ship transmitters exceeded public safety limits on bridge roofs with EMF levels reaching 3.70 V/m in passenger areas.
Plain English Summary
Scientists measured radio waves from ship transmitters across three deck levels, taking 528 measurements. They found EMF levels on the bridge roof exceeded safety limits for the general public but stayed within workplace exposure limits, providing crucial data for maritime EMF safety standards.
Why This Matters
This research fills a critical gap in our understanding of EMF exposure in maritime environments, where multiple high-powered transmitters operate simultaneously in confined spaces. The finding that general public safety limits were exceeded on the bridge roof is significant because many commercial vessels carry passengers who aren't trained maritime workers. What makes this particularly concerning is that the measured levels of 2.15-3.70 V/m on the bridge roof are substantial - for comparison, typical cell phone tower emissions at ground level are often much lower. The reality is that maritime vessels represent a unique EMF environment where multiple radio systems operate in close proximity to occupied areas, creating exposure scenarios that current safety guidelines may not adequately address for all users of these vessels.

Exposure Context
This study used 0.82–0.86, 2.15–3.70, and 0.47–1.15 V/m for electric fields:
- 1.6x above the Building Biology guideline of 0.3 V/m

In this paper, we provide a new data collection model for future surveys, which could be conducted with larger samples to verify our observations. Furthermore, this new method could be useful as a reference for researchers and industry professionals without direct access to the necessary equipment
