Achọtala ihe ndị nwere alfa (α) nuclides na sediments na mmiri okirikiri nke reactor no. 2 nke Fukushima Daiichi Ngwá Ọrụ Ike Nuclear (FDiNPS). A tụlere Uranium (U), bụ isi ihe na-emepụta mmanụ ụgbọ ala, site na nyocha eletrọnịkị microscope (SEM). Achọpụtara α-nuclides ndị ọzọ (plutonium [Pu], americium [Am] na Curium [Cm]) site na mpaghara α, na nyocha nke morphology nke α-nuclide particles site na nyocha SEM energy spectrum analysis (EDX). Ahụrụ ọtụtụ irighiri ihe uranium sitere na submicron ruo ọtụtụ microns site na nyocha microscopy eletrọn. Ihe ndị a nwere zirconium (Zr) na ihe ndị ọzọ mejupụtara ihe mkpuchi mmanụ na ihe nhazi. Oke isotope 235U/238U na akụkụ siri ike (gụnyere U irighiri ihe) kwekọrọ na mmanụ nuklia achọtara na reactor no. 2. Nke a na-egosi na uranium nke otu mmanụ ụgbọala mejupụtara na-aghọ mma.
