Likarolo tse nang le li-nuclide tsa alpha (α) li fumanoe ka har'a sediment ka metsing a chitja a reactor no. 2 ea Setsi sa Matla a Nyutlelie ea Fukushima Daiichi (FDiNPS). Uranium (U), e leng karolo e ka sehloohong ea mafura a nyutlelie, e ile ea hlahlobjoa ka ho hlahloba microscope ea elektronike (SEM). Li-α -nuclide tse ling (plutonium [Pu], americium [Am] le Curium [Cm]) li ile tsa fumanoa ke α locus, 'me morphology ea likaroloana tsa α -nuclide e ile ea hlahlojoa ke SEM energy spectrum analysis (EDX). Likaroloana tse 'maloa tsa uranium ho tloha ho submicron ho ea ho li-micron tse' maloa li ile tsa fumanoa ka ho hlahloba microscope ea elektronike. Likaroloana tsena li na le zirconium (Zr) le lintho tse ling tse etsang likhahla tsa mafura le thepa ea meralo. Karo-karolelano ea 235U/238U ea isotope karolong e tiileng (ho kenyeletsoa le likaroloana tsa U) e lumellana le mafura a nyutlelie a fumanoang ho reactor no. 2. Sena se bontša hore uranium ea motsoako o tšoanang oa mafura e ba ntle haholoanyane. Likarolo tse nang le li-nuclide tse khetholloang ke tlhahlobo ea alpha trajectory li fapana ka boholo ho tloha ho mashome ho isa ho makholo a li-micron. Tlhahlobo ea spectroscopic ea EDX e bontša hore likaroloana tsena li na le tšepe haholo. Pu, Am le Cm li adsorbed holim'a likaroloana tsa Fe ka lebaka la palo e nyenyane ea α -nuclide. Phuputso ena e hlakisa liphapang tsa mefuta e hlahelletseng ea U le li-alpha nuclide tse ling ka har'a depositi ea hydroponic ea kamore ea selemo ea FDiNPS 2 reactor. Setsi sa matla a nyutlelie sa Tepco sa Fukushima Daiichi (FDiNPS) se senyehile haholo ke tšisinyeho ea lefatše ea la 11 Hlakubele 2011 le tsunami e ileng ea latela. Ka nako eo, likarolo tsa 1-3 tsa li-reactor tse tšeletseng li ne li sebetsa, 'me mafura a nyutlelie ka likarolo tsa 1-3 a senyehile. Metsi a leoatle le metsi a hloekileng a kenngoa ho tlosa mocheso o bolileng oa mafura a nyutlelie. Metsi a sala a le mokatong o ka tlaase oa mohaho, moo likarolo tsa mafura a nyutlelie li qhalanang, 'me li etsa letamo la metsi a nang le mahlaseli a kotsi haholo. Metsi a shoeleng a na le li-radionuclides tse kang lihlahisoa tsa fission le li-actinide tsa mafura a nyutlelie. Theha ts'ebetso ea kalafo ea lik'hemik'hale ho tlosa li-radionuclide, ho theha sistimi ea boenjiniere ba potoloho, le ho khutlisa metsi a pholileng hore a sebelisoe hape. Ho tloha ka nako eo, palo ea metsi a emeng e fokotsehile butle-butle, empa likaroloana tse ntle tse nang le likhahla tse phahameng tsa alpha (α) radionuclides li fumanoe ka tlas'a lefatše mehahong ea li-reactor. Li-alpha nuclides (102-105 Bq/L) metsing a emeng, ho kenyeletsoa le sediment, li phahame ho feta metsing a pholileng mehahong e ka tlaase. Li-radiated radionuclides, joalo ka uranium (U) le plutonium (Pu), li ka baka ts'oaetso e matla ea kahare ha li kena 'meleng. α -nuclide ke nuclide e ka sehloohong ea lihlahisoa tsa fission 'me e lokela ho laoloa ka thata ha e bapisoa le cesium (Cs) -137 le strontium (Sr) -90. Mekhoa ea ho tlosa li-alpha nuclide metsing a emeng e tlameha ho ntlafatsoa. Ho fihlela sena, metsi a emeng a ile a bokelloa phaposing ea selemo e mokatong o ka tlase oa moaho oa setsi sa 2, 'me seretse se metsing a emeng se ile sa hlahlojoa ka tlhahlobo ea radiochemical. Mehlala e nang le likarolo tse tsoakaneng tsa seretse ho tsoa metsing a emeng a moaho o netefalitseng boteng ba alpha radionuclides. Bakeng sa ho tsoela pele ho phekola metsi a emeng botebong ba meaho ea merafo nakong e tlang, ho hlokahala kutloisiso e betere ea mefuta e fapaneng ea li-alpha emitters, haholo-holo tse nang le lintho tse tiileng metsing a emeng. Phuputsong ena, likaroloana tsa radioactive tse amanang le Cs particles (CsMPs) li ile tsa fumanoa ka ntle ho sebaka sa FDiNPS, 'me sebopeho sa bona sa' mele le lik'hemik'hale le morpholoji li ile tsa hlahlojoa 3, 4, 5, 6, 7, 8. Abe et al. e ile ea bokella li-CsMP tse hlahisoang ke FDiNPS ho tloha sepakapakeng 'me ea li hlahloba ka ho sebelisa li-X-rays tse lumellanang ho lemoha U ho CsMPs. Ochiai et al. e fumane li-nanometer tse makholo tsa likaroloana tsa U ho CsMP ka tlhahlobo ea SEM-EDX. Mokhoa oa diffraction oa UO2 holim'a magnetite o ile oa bonoa ka microscope ea elektronike ea phetisetso, 'me liphetho li ne li bontša sebopeho sa UO2. Ka mokhoa o ts'oanang, mekhoa ea diffraction ea UO2 le zirconia e ile ea fumanoa bakeng sa likaroloana tse tsoakiloeng tsa Zr le U ho CSMP. Sena se bontša hore U e teng ho CsMP ka sebopeho sa UO2 le U-Zr nanocrystals. Kurihara et al. 8 e hlahlobile litekanyo tsa isotope tsa 235U le 238U ho CsMP ka nanoscale sub-ion mass spectrometry mme ea fumana hore ho na le U ka sebopeho sa mafura sa reactor no. 2 ho CsMP. Litlhahlobo tsa mobu 9, 10, 11, 12, 13, likaroloana tse tsamaisoang ke moea le CsMPs7 le tsona li tlalehile ho lokolloa ha mafura a tsoang ho polyurethanes tikolohong. Buddha
