50, 57, 64 and 76 hours post detonation. 78 hours post detonation (0C68). Evacuation at Utirik was completed at These assumed water intakes led to estimates of ingested activity which were tabulated in Table 7. This was a conservative estimate of radioiodine activity intake from this pathway because all the activity in the liquid phase in the cistern was assumed to be due only to the iodine isotopes. 3. Activity in Food Preparation and consumption of food in the open was a common prac~ tice among the Marshallese people (Na83). food (see Figures 9-15). Fallout was ingested directly with Food was reported to taste strange by persons interviewed at Rongelap during the 1954 evacuation (Sh57). Fallout was reported at Rongelap to appear like table salt and flour, or like taro powder or chalk dust, and taste like cement and blackened the sky as if night were approaching (Sh57). One family group reported that the only food not dusted by fallout was coconut meat and milk (Sh57). Most families reported eating in the usual open air style and prepared foods such as cooked pumpkin, starch tubes, rice and bread products over open campfires. In addition, fish was normally dried on open air racks prior to intake. 4. Activity Ingested with Food The majority of activity fell during the afternoon at Rongelap Is~ land during preparation of the mid-day and evening meals. Fallout was even visi- ble on peoples skin; it caused itching, sneezing and coughing (Sh57). The open air living pattern of the Marshallese led to direct ingestion of BRAVO fallout in amounts which can only be estimated roughly. The living patterns at Utirik and Sifo were similar to those at Rongelap and, at Utirik the fallout was not visible during or following deposition (0C68). 27 No attempt at removing visible
