Cytogenetic and hematological analyses were performed
on the peripheral blood lymphocytes (PBLs) obtained
from Korean native cattle bred in the vicinity of three
nuclear power plants (Wolsong, Uljin and Yeonggwang)
and in a control area. The micronucleus (MN) rates for
the cattle from the Wolsong, Uljin and Yeonggwang
nuclear power plants and for the control area were 9.87 กพ
2.64, 8.90 กพ 3.84, 9.20 กพ 3.68 and 9.60 กพ 3.91 per 1,000
cytokinesis-blocked lymphocytes, respectively. The apparent
difference is not statistically significant. The MN frequencies
of PBLs from cattle bred in the four areas are within the
background variation for this study. The MN frequencies
and hematological values were similar regardless of
whether the cattle were bred near a nuclear power plant
or in the control area.
