A more recent report (35)listed a total of 249 Marshallese who were exposed at Rongelap (n = 67), Ailingnae (n = 19), and Utirik (n = 163). This total included 12 individuals who were in-utero at the time of the incident (3, 1, and 8 at Rongelap, Ailingnae, and Utirik, respectively) . The exposed population comprised individuals of different ages ranging from those in-utero to the elderly as shown in Table 2. Table 2.
