An international team of researchers (Malaysia, France, USA – UC Berkeley, Berkeley Lawrence Livermore National Laboratory) recovered complex association of millimeter-sized, aerodynamically-shaped debris, including glass spherules, glass filaments, and composite-fused melt particles was from beach sands on the shores of the Motoujina Peninsula in Hiroshima Bay, Japan. These paticles are generally produced by single high-energy catastrophic events, such as an extraterrestrial body impacting Earth or a nuclear explosion. This study interprets the large volumes of fallout debris generated under extreme temperature conditions as products of the Hiroshima August 6th, 1945 atomic bomb aerial detonation. The chemical composition of the melt debris provides clues to their origin, particularly about city building materials…read more. Open Access TECHNICAL ARTICLE
