-21~ .- Fertility Effects of radiation exposure on fertility is difficult to assess in the Mershellese. If there has been any effect on fertility it must have been very short lived since pregnancies are occurring normally and at rete similar to other groups of Marshallese, Pregnan There bas been’no apparent effects of radiation on the course of pregnancy in the Marshallese. Since the delivery of the four women who were pregnant at the time cf the event, there have been twelve pregnancies which have terminated. Ten of these términated normally, one terminated in a stillbirth and one baby died several hours after birth apparently of an infection of the cord, tal statistics makes this data difficult to interpret.

Effects on the Fetus The three babies irradiated in-utero have not shown any abnormalities such as wes observed in ome of the Japanese tabies irradiated in-utero (for example microcephaly).

Anthropometri Since the nuabers of children are small the data is not easily subjected to statistical analysis. However there does appear to be evidence suggestive of a slight inpedrment of growth and development as meesured by comparison of height and weight in the control and exposed children, Ko abnormalities of the eyes have been observed.
