most frequent findings, active chronic impetigo
and palpable liver over 3 cm in size, were tabulated separately for several different age groups
(Tables 7 and 8). The ages were based on thebest
available birth date estimations. A tendency for
these findings to occur more frequently in the
younger children was noted. The incidences, however, did not appear to be related to exposure to
radiation.
