individuals have had a clinically significant depression of any cell type (8).
Hemoglobin/hematrocrit levels have been virtually identical to the unexposed (Figure 3).

Immunologic Status

In 1957 the first of several tests for evaluating the immune function of exposed Marshailese
was performed (16). The serologic responses to primary and secondary challengesof tetanus toxoid

were found notto be significantly different between exposed and unexposed persons, although the
range of titers was great, the numberof persons tested was small, and the primary response was

somewhat lower in the exposed. In 1959 complementfixation tests for a battery of viral and
rickettsial disease (including influenza, mumps, and adenovirus) were performed. The Rongelap
group had lower meantiters than the comparison group for most antibodies tested, Nosignificant
