APPENDIX SAMPLE CASE INTERVIEW After being evacuated to Kwajalein on 2 March 1954, all of the military personnel assigned to Rongerik Atoll were interviewed to determine their specific activities during the period 1 March until their subsequent evacuation on 2 March. Some of the interviews provided sufficient detail to determine an individual's activities, hence his whereabouts, on an hour-to-hour basis. Because the film badge dose estimates in this memorandum are based on seventeen such interviews, this appendix shows how these data are utilized in calculating the film badge doses. Reference 3 contains a summary of the interviews obtained from the 28 military personnel after being evacuated to Kwajalein. The results of an interview with CN 406, extracted from Reference 3, is as follows: CN406 Duty. Rawinsonde Operator. Activities. 1 March: On duty day of 1 March until 1630. Took shower before chow. Attended movie in messhall. 2 March: Worked outside, helping to wash outside of messhall. Clothing. Wore shorts until 1530. Changed to long clothing. Food and Drink. Ate evening meal | March. Had coffee for breakfast, 2 March. No lunch. Fallout. Observed fallout at about 1500. "White ashes; light, floated down." Film Badge. None. CN408 wore badge for group. Evacuated. In first group (1245, 2 March). Note: High school education. Thirteen months remaining of present enlistment. Based on the interview with CN406, it is possible to estimate where this individual was at a particular time and, hence, determine what radiation protection was provided by the particular building he was in. When particular structure was not specified, it was assumed he was outdoors (PF=1.0). Table 6 details the activities of CN406 as inferred from his interview, and lists the calculated film badge dose for this individual during his stay on Rongerik. 34
