[Dynamics of 134 + 137Cs accumulation in insects inhabiting the 30-kilometer zone of Chernobyl Nuclear Power Station].
Accumulation of the specific activity of 134 + 137Cs in insects was investigated in the most typical biogeocenoses within the 30-km zone of the Chernobyl NPP. The studied biogeocenoses had different rates of the exposure doses. It was shown that the specific activity of 134 + 137Cs in the insects inhabiting forest biotops was of the same order that in the crown, whereas in the insects inhabiting open biotops the specific activity was higher than in plants. Two periods of the increased 134 + 137Cs content in insects were found: May and September. Along with seasonal activity variations, a tendency to decreasing and stabilization of 134 + 137Cs content was observed during the period of the study.
