Health hazard evaluation report: HETA-2003-0111-2909, Ethicon Endo-Surgery, Cincinnati, Ohio.
NIOSH 2003 Aug; :1-12
On December 20, 2002, the National Institute for Occupational Safety and Health (NIOSH) received a Health Hazard Evaluation (HHE) request from management at Ethicon Endo-Surgery (EES) in Cincinnati, Ohio, to evaluate occupational exposure to radio-frequency (RF) radar emissions from an adjacent Ohio Air National Guard (OANG) facility. RF was measured in the 2.9 - 3.1 GigaHertz [GHz] range at the source of the radar (approximately 5 feet from the rotating radar transmitter) and at various points along the beam path (which is in direct alignment with the EES facility). All equipment used to document exposure was calibrated by the manufacturer approximately one month prior to the survey. The only power density measurement above the detection limit of the instrument was recorded 5 feet away from the hilltop rotating radar transmitter, at 0.33 milliwatts/square centimeter (mW/cm 2 ). This location is approximately 2500 ft from EES. The remaining levels were all below the limit of detection of the instrument (0.02 mW/cm 2 ), which is approximately 100 times below the Institute for Electrical and Electronic Engineers (IEEE) exposure limit for the general population. The NIOSH investigators determined that no health hazard existed from exposure to RF. Computer monitors and radio reception interference in the EES office is due to RF levels far below all applicable criteria.
