ID Number		1306
Study Type		Human / Provocation
Model		Occupational exposure from EM fields (radar workers, air traffic controlers, video display unit operators) and analysis of hematological effects and subjective complaints
Details		Radar operators (n = 43) employed as air traffic controllers were analyzed over a 4 year period for hematological parameters and correlations with occupational exposure to microwaves, heat, soft X-ray radiation, and noise. The authors report that occupational exposure correlated with a decreased number of erythrocytes, reticulocytes, platelets, segmented granulocytes and monocytes, and an increased number of leucocytes and lymphocytes. The changes were not pathologically significant and most were reversible. In related studies, video display terminal operators (n = 49) were questioned regarding subjective complaints via a questionnaire. The authors report a high occurrence of such complaints with the terminal operators, although measurements of non-ionizing and ionizing radiation emissions of the terminals showed them to be within permissible levels.
