  "main_findings": "In 43 radar operators occupationally exposed to low-intensity microwave radiation over four years, several blood cell counts decreased (erythrocytes, reticulocytes, platelets, segmented granulocytes, monocytes) while leucocytes and lymphocytes increased. The reported changes were not pathologically significant and most were reversible.",
