Abstract

事故翌年における果実発育期間中の果実中の放射性セシウム濃度の変化を調査した。放射性セシウム濃度は満開後15日で最も高くその後低下し,50日以降はほぼ一定であった。モモの果実と葉の放射性セシウム濃度と<sup>40</sup>K濃度の動態には差異が生じた。福島県内の24園地より採取した満開後60日果実と収穫果実の<sup>137</sup>Cs濃度を比較することで,摘果果実を用いた成熟果の放射性セシウム濃度の予測の可能性について検討した。

<i>To explore the predictability of radiocaesium concentration in the mature peach fruits based on the radiocaesium concentration in the young superfluous fruits picked at the fruit thinning period, the change in the radiocaesium concentration as well as potassium</i>(<sup>40</sup>K)<i> in peach fruits associated with fruit growth was monitored during the second year after the accident of the nuclear power plant in Fukushima. Radiocaesium concentration was found to be highest in the fruit 15 days after the full bloom stage, followed by the gradual decrease before harvest. In addition, variation of radiocaesium and </i><sup>40</sup>K<i> concentration with time was shown to be different in leaves and fruits. Finally, the young fruits 60 days after the full bloom date and the ripe fruits were taken from 24 orchards in Fukushima to compare their radiocaesium levels. The predictability of radiocaesium concentration and some considerations for practical use are discussed.</i>
