Description

Radiocaesium pollutants on the pinecones contaminated were measured by a germanium semiconductor detector and autoradiography in 2013 - 2015. The 137Cs concentration of gray pinecone in 2015 around Fukushima Prefecture was high and they were weak correlations between the dose rate map of November, 2011 and some strongly spot were shown in the autoradiography. It was thought that the falling gray pinecones of Pinus densiflora were including high radiocaesium pollution in Northern Fukushima Prefecture after 2015 for a while. (author)

Abstract (Japanese)

2015年におけるマツカサの放射性セシウム汚染を,ゲルマニウム半導体検出器とオートラジオグラフィーで調査した。2015年採取のアカマツの灰色マツカサにおける137Cs濃度は,2013年の予想に反して2011年と同程度の高濃度汚染であった。アカマツの灰色マツカサの137Cs濃度は,2011年に空間線量率が高かった場所で高濃度の傾向があった。高濃度汚染マツカサ表面のオートラジオグラフィーを行うと,不規則な強いスポットが観察された。福島のアカマツの灰色マツカサは,2015年以降もしばらくは高濃度の放射性セシウムに汚染のものが含まれると思われた。(著者)
