Description/Abstract:
A REPORT ON A RADIATION ACCIDENT IN WHICH A TECHNOLOGIST WAS IN CLOSE PROXIMITY FOR 40 SECONDS TO A SOURCE CONTAINING 7,700 CURIES OF COBALT 60. THE AVERAGE BONE MARROW DOSE WAS ESTIMATED AT 118 RADS. WITHIN THE FIRST 24 HOURS POSTEXPOSURE, LYMPHOPENIA DEVELOPED AND AFTER TWO WEEK, THE PLATELET AND GRANULOCYTE COUNT BEGAN TO FALL AND REACHED NADIR AT APPROXIMATELY FOUR WEEKS. DURING THE PHASE OF GRANULOCYTE DEPRESSION, THE PROTECTIVE ENVIRONMENT OF A LAMINAR AIRFLOW FACILITY WAS BELIEVED TO HAVE LESSENED THE RISK OF INFECTION. THIS PATIENT'S HEMATOLOGICAL RECOVERY WAS COMPLETE IN SIX WEEKS. AFTER EXPOSURE TO HIGHER DOSES OF RADIATION THAN THIS PATIENT RECEIVED, RECOVERY CAN OCCUR IF APPROPRIATE SUPPORTIVE CARE, RANGING FROM REST AND OBSERVATION TO MARROW TRANSPLANTATION, IS EMPLOYED. THE CLINICAL COURSE, LABORATORY DATA, AND ESTIMATED DOSE-EXPOSURE WILL DICTATE WHAT TYPE OF THERAPY IS NEEDED. EACH CASE MUST BE INDIVIDUALLY EVALUATED.
