Health hazard evaluation report, HETA-2004-0064-2933, ISCO International, Mt. Prospect, Illinois.

NIOSH 2004 Mar; :1-6
On November 26, 2003, the National Institute for Occupational Safety and Health (NIOSH) received a confidential employee request for a health hazard evaluation (HHE) at ISCO International in Mt. Prospect, Illinois. The requestor expressed concerns about possible excessive exposures to radiofrequency (RF) radiation while working near or at the minimum detectable signal (MDS) station. Reported symptoms included skin rashes, sunburn-like redness and swelling of face and back, burning feeling in the eyes, headaches, fatigue, elevated temperature, and diarrhea. The test transmitters were reportedly active throughout the day even when no products were being tested. On February 2, 2004, NIOSH investigators completed a source characterization of the RF fields emitted from the testing station at ISCO International. This evaluation assessed occupational exposure to RF fields in the frequency range from 0.3 to 3,000 megahertz (MHz) among workers during a typical daily work regimen. All measurements taken with the Narda Shaped Frequency Response Probe 8742D, combined with the Narda Model 8718B Electromagnetic Radiation Survey Meter, were below the occupational exposure limits of 2.7 to 3.0 milliwatts per square centimeter (mW/cm2) recommended by the U.S. Federal Communication Commission for frequencies between 800 to 900 MHz. Further, all of the measurements were below 1.5 percent of the limit, which indicates that the emissions from this testing station pose no threat to employees or the general population who visit or pass through the area. No RF exposure hazards exist from the testing station located at the ISCO International manufacturing facility. This conclusion is based on the RF measurements taken on February 2, 2004, which were all below any RF exposure limits for the general population or occupational work environments.
