Y Type Liquid kānana kānana no nā ʻāpana i loaʻa nā Alpha Emitters i ka wai make i loko o ka Reactor Annular Chamber o Unit 2 o Fukushima Daiichi Nuclear Power Plant.

Mahalo iā ʻoe no kāu kipa https://likvchina.goodao.net/, ke hoʻohana nei ʻoe i kahi kākoʻo polokalamu kele pūnaewele no CSS co., LTD. No ka ʻike maikaʻi loa, manaʻo mākou e hoʻohana ʻoe i kahi polokalamu kele hou (a i ʻole e hoʻopau i ke ʻano hoʻohālikelike ma Internet Explorer). I kēia manawa, e hōʻoia i ke kākoʻo mau, e hōʻike mākou i ka pūnaewele me ka ʻole o nā ʻano a me JavaScript. Loaʻa nā ʻāpana i loaʻa nā alpha (α) nuclides i loko o nā sediment i loko o ka wai pōʻai o ka reactor no. 2 o ka Fukushima Daiichi Nuclear Power Plant (FDiNPS). ʻO ka Uranium (U), ka mea nui o ka wahie nuklea, ua nānā ʻia e ka scanning electron microscope (SEM). ʻO nā α -nuclides ʻē aʻe (plutonium [Pu], americium [Am] a me Curium [Cm]) ua ʻike ʻia e ka α locus, a ua kālailai ʻia ka morphology o nā ʻāpana α -nuclide e ka SEM ikehu spectrum analysis (EDX). Ua ʻike ʻia kekahi mau ʻāpana uranium mai ka submicron a i kekahi mau microns ma ka scanning electron microscopy. Aia i loko o kēia mau ʻāpana ka zirconium (Zr) a me nā mea ʻē aʻe e hana ai i ka uhi wahie a me nā mea hana. ʻO ka lākiō isotope 235U/238U i ka hakina paʻa (me nā ʻāpana U) ua kūlike me ka wahie nuklea i loaʻa ma ka reactor no. 2. Hōʻike kēia i ka ʻoi aku ka maikaʻi o ka uranium o ka hui wahie like. ʻO nā ʻāpana i loaʻa nā nuclides i ʻike ʻia e ka alpha trajectory analysis ka nui mai ka ʻumi a hiki i nā haneli microns. Hōʻike ka loiloi spectroscopic EDX he hao ka nui o kēia mau ʻāpana. Hoʻopili ʻia ʻo Pu, Am a me Cm ma nā ʻāpana Fe ma muli o ka liʻiliʻi o ka α -nuclide. Hōʻike kēia haʻawina i nā ʻokoʻa o nā ʻano nui o U a me nā alpha nuclides ʻē aʻe i loko o nā waihona hydroponic o ke keʻena annular o FDiNPS 2 reactor. Ua hoʻopōʻino nui ʻia ʻo Tepco's Fukushima Daiichi nuclear power plant (FDiNPS) e ke ōlaʻi ma Malaki 11, 2011 a me ke kai eʻe. I kēlā manawa, e hana ana nā ʻāpana 1-3 o nā reactors ʻeono, a ua pōʻino ka wahie nuklea ma nā ʻāpana 1-3. Hoʻokomo ʻia ka wai kai a me ka wai maʻemaʻe e wehe i ka wela palaho mai ka wahie nuklea. Noho ka wai ma lalo o ka hale, kahi e hoʻoheheʻe ai nā ʻāpana o ka wahie nuklea, e hana ana i kahi wai radioactive nui o ka wai. Loaʻa i ka wai make nā radionuclides e like me nā huahana fission a me nā actinides wahie nuklea. E hoʻokumu i ke kaʻina hana kemika no ka wehe ʻana i nā radionuclides, hoʻokumu i ka ʻōnaehana ʻenekinia kaʻapuni, a hoʻihoʻi hou i ka wai anuanu no ka hoʻohana hou ʻana. Mai ia manawa, ua emi mālie ka nui o ka wai kū, akā ua ʻike ʻia nā ʻāpana maikaʻi i loaʻa nā kiʻekiʻe kiʻekiʻe o nā radionuclides alpha (α) ma lalo o ka lepo i loko o nā hale reactor. ʻOi aku ka kiʻekiʻe o ka nui o nā alpha nuclides (102-105 Bq/L) i ka wai kū, me ka sediment, ma mua o ka wai anuanu ma nā hale o lalo. Hiki i nā radionuclides i hoʻomālamalama ʻia, e like me ka uranium (U) a me ka plutonium (Pu), ke hōʻeha nui i ka ʻike i loko ke komo lākou i ke kino. ʻO α -nuclide ka nuclide nui o nā huahana fission a pono e hoʻomalu pono ʻia me ka cesium (Cs) -137 a me ka strontium (Sr) -90. Pono e hoʻomohala ʻia nā ʻenehana no ka wehe ʻana i nā alpha nuclides mai ka wai kū. No kēia hopena, ua hōʻiliʻili ʻia ka wai paʻa i loko o ke keʻena annular ma ka haʻahaʻa o ka hale reactor o Unit 2, a ua loiloi ʻia ka sediment i loko o ka wai stagnant e ka loiloi radiochemical. Ua hōʻoia ka loaʻa ʻana o nā radionuclides alpha i loko o nā laʻana i loaʻa nā ʻāpana lepo hui ʻia mai ka wai kū o ka hale reactor. I mea e hoʻomau ai i ka mālama ʻana i ka wai kū i ka hohonu i loko o nā hale reactor i kēia mua aku, pono ka ʻike maikaʻi ʻana i nā ʻano like ʻole o ka alpha emitters, ʻoi aku ka poʻe i loaʻa nā mea paʻa i loko o ka wai kū. I loko o kēia noiʻi, ua ʻike ʻia nā ʻāpana radioactive e pili ana me nā mea Cs (CsMPs) ma waho o ka pūnaewele FDiNPS, a ua kālailai ʻia ko lākou kino a me kemika a me ka morphology 3, 4, 5, 6, 7, 8. Abe et al. hōʻiliʻili ʻia nā CsMP i hoʻokuʻu ʻia e FDiNPS mai ka lewa a nānā iā lākou me ka hoʻohana ʻana i nā kukui X synchronous e ʻike iā U i nā CsMPs. Ochiai et al. ua ʻike ʻia he mau haneli nanometer o nā ʻāpana U ma CsMP e ka nānā ʻana SEM-EDX. Ua ʻike ʻia ke ʻano ʻokoʻa o ka UO2 ma ka magnetite e ka microscope electron transmission, a ua hōʻike nā hopena i ke ʻano o UO2. Pēlā nō, ua loaʻa nā ʻano ʻokoʻa o UO2 a me zirconia no nā ʻāpana hui ʻia o Zr a me U ma CSMP. Hōʻike kēia aia ʻo U ma CsMP ma ke ʻano o UO2 a me U-Zr nanocrystals. Kurihara et al. 8 kālailai i ka isotope lākiō o 235U a me 238U ma CsMP e nanoscale sub-ion nuipa spectrometry a loaa ia U i loko o ka wahie haku mele o reactor no. 2 ma CsMP. Ua hōʻike pū ʻia nā loiloi lepo 9, 10, 11, 12, 13, nā ʻāpana lewa a me CsMPs7 i ka hoʻokuʻu ʻana i nā polyurethanes i loaʻa i ka wahie i loko o ke kaiapuni. ʻO ka Buddha
