  "main_findings": "A single case described momentary exposure of the right hand to microwave oven irradiation, resulting in transient paresthesias and a cold, pale hand that resolved spontaneously within 60 minutes without treatment. The report notes that even momentary exposure can result in severe coagulation necrosis with possible eventual loss of the exposed extremity.",
