山田怜央院生の論文が学術誌"Radiation Measurements"に掲載されました

今春に修士課程を修了した山田怜央元院生の論文" Hydroxyl group formation and specific damage structures in gamma-exposed PADC track detector（ガンマ線を照射したPADC飛跡検出器中に生成するヒドロキシル基とその特異な構造）"が学術誌"Radiation Measurements"に掲載されました。固体飛跡検出器は化学エッチングによって放射線の通り道を拡大・可視化する検出器ですが、陽子には検出閾値が明確に存在する一方で、ガンマ線照射にはそれはありません。その理由を説明するモデルを世界で初めて提案しており、新しい検出器開発への道を開くものです。オープンアクセスです。https://doi.org/10.1016/j.radmeas.2026.107763

最終著者の山内教授によると、「20年以上に渡る研究の一里塚です。山田元院生が筆頭著者を務める論文は2つ目であり、博士課程に進まなかったことが悔やまれます」とのことです。

Reo Yamada’s academic paper has been published in the journal "Radiation Measurements"

The second paper by Reo Yamada, a former postgraduate student who completed his Master’s degree this spring, entitled ‘Hydroxyl group formation and specific damage structures in gamma-exposed PADC track detectors’, has been published in the academic journal Radiation Measurements. Solid-state track detectors are devices that use chemical etching to enlarge and visualise the path taken by radiation; whilst there is a clear detection threshold for protons, no such threshold exists for gamma-ray irradiation. This paper proposes the world’s first model to explain the reason for this, paving the way for the development of new detectors. It is available as open access. https://doi.org/10.1016/j.radmeas.2026.107763

According to Professor Yamauchi, the last author, "This study marks a milestone in over 20 years of research. This is the second paper for which former postgraduate student Yamada is the lead author, and I regret that he did not proceed to doctoral studies."
