Abstract

Epidemiological studies related to radiofrequency (RF) electromagnetic fields (EMF) have mainly used crude proxies for exposure, such as job titles, distance to, or use of different equipment emitting RF EMF. The Royal Norwegian Navy (RNoN) has measured RF field emitted from high-frequency antennas and radars on several spots where the crew would most likely be located aboard fast patrol boats (FPB). These boats are small, with short distance between the crew and the equipment emitting RF field. We have described the measured RF exposure aboard FPB and suggested different methods for calculations of total exposure and annual dose. Linear and spatial average in addition to percentage of ICNIRP and squared deviation of ICNIRP has been used. The methods will form the basis of a job exposure matrix where relative differences in exposure between groups of crew members can be used in further epidemiological studies of reproductive health.

Main findings

RF fields from high-frequency antennas and radars were measured at multiple locations on fast patrol boats where crew would likely be located. The paper describes the measured exposure and proposes several approaches to summarize exposure and estimate total exposure/annual dose, intended to support development of a job exposure matrix.

Outcomes measured

  • Measured RF field levels at crew locations aboard fast patrol boats
  • Methods for calculating total exposure and annual dose (e.g., linear/spatial averages; percent of ICNIRP; squared deviation of ICNIRP)
  • Basis for a job exposure matrix for future epidemiological studies (reproductive health mentioned as future application)

Limitations

  • No health outcomes reported (methods/dose assessment focus)
  • Frequencies and quantitative exposure levels not provided in the abstract
  • Sample size/number of boats or measurements not stated in the abstract
