Outline of Final Research Achievements

Since many radioactive nuclides spontaneously emit X-rays, we investigated whether radioactive nuclides in contaminated soil can be detected by the X-ray measurements. First, X-ray spectra were measured for Cs-137 and Sr-90 standard reference sources. Based on the obtained basic data, X-ray spectra were measured for contaminated soil collected in Fukushima Prefecture. As a result, it was clarified that Cs-137 can be quantitatively analyzed by measuring Ba KαX-rays. For highly contaminated soil, Zr Kα X-rays emitted from Sr-90 were also detected, which indicated that radioactive nuclides that do not emit any gamma-ray can also be detected by measuring X-rays.

Academic Significance and Societal Importance of the Research Achievements

本研究により、Sr-90などガンマ線を全く放出しない核種を含め、放射性核種から自発的に放出される特性X線のエネルギー、強度などを精密に測定したことは、従来から核データが十分ではなかったX線の放出に関して基礎データを提供した点において、学術的意義がある。一方、X線測定によりCs-137の定量、Sr-90の検出ができたことは、放射線汚染土壌などの簡便な放射能分析に道を拓くものであり、社会的意義が大きいと考える。
