counts of all four components with increasing age
at the time of radiation. There was no evidence
at the 3% level of any sex difference for any of the
blood components exceptplatelets, for which the
male count wassignificantly lower (1% level) than
the femaie count.
“There was no evidenceat the 1% level that
significant. For lymphocytes there was evidence
at the 5% level of an interaction between exposure

and sex, and for neutrophils there was evidence
at the 3% level of an interaction between exposure
and year. The four-factor interaction was treated
as error, an assumption which appearedjustified °
upon examination of the variances. Since these
data are being further analyzed, no interpretation
as to biological significance of the above interactlonsis justified at present.”
