Doses were calculated from average exposure rates for each atoll,
Multiple year dose calculations were made on the background substracted exposure rate.
assumed to be the average of exposure rates detected at Ailuk and Wotje Atolls.
Dose represents increase over background.
Conservatively assumes 100 percent of time spent on Utirik Island.
Based on a superficial survey of Eniwetak Island only.
Background was
