Abstract: | The large number of radio frequency (RF) transmitters employed in modern marine platforms requires that they operate in mutual
coexistence while posing no danger to operators and equipment despite the limited available physical space. A key to the successful
system integration is the control of the electromagnetic environment on the ships’ topsides, which might pose radiation hazards
(RADHAZ) to personnel (HERP). HERP are caused by transmitter antenna installations that generate intentional EM radiation
in excess of the safe levels in zones of personnel activity. Radiation safety to personnel is achieved when the average radiation
power density is below the permissible exposure limits (PEL) for HERP at locations of personnel activity and medical equipment
operation. This paper describes the analysis tools and techniques for the evaluation of HERP on marine platforms. The same
approaches could be employed in the analysis of land site antenna deployment scenarios. |
