Thaum 1 teev tsaus ntuj thaum Lub Yim Hli 24, 2023, tsoomfwv Nyij Pooj tsis quav ntsej txog kev tsis ntseeg siab thiab kev tawm tsam ntawm cov zej zog thoob ntiaj teb thiab unilaterally yuam kom tso cov dej tsis huv los ntawm Fukushima nuclear kev sib tsoo.Qhov Nyij Pooj tau ua yog txhawm rau hloov kev pheej hmoo rau lub ntiaj teb, txuas ntxiv qhov mob rau noob neej yav tom ntej, ua kev puas tsuaj ntawm ib puag ncig ecological thiab lub ntiaj teb Marine polluter, ua txhaum txoj cai rau kev noj qab haus huv, kev loj hlob thiab ib puag ncig ntawm txhua lub teb chaws, thiab ua txhaum nws. lub luag hauj lwm ncaj ncees thiab txoj cai thoob ntiaj teb.Nyiv cov kab ntawm cov dej tsis huv nuclear yuav raug txim los ntawm cov zej zog thoob ntiaj teb mus ntev.Tsoomfwv Suav yeej ib txwm muab cov neeg ua ntej thiab yuav ua txhua yam kev ntsuas tsim nyog los tiv thaiv zaub mov kev nyab xeeb thiab kev noj qab haus huv ntawm cov neeg Suav.
Tom qab tso dej pov tseg los ntawm Nyiv, tus nqi ntawm tritium pom nyob rau hauv Marine ib puag ncig yuav nce, uas yuav cuam tshuam rau Marine ecosystem.Raws li lub tebchaws tseem ceeb hauv hiav txwv, Tuam Tshoj txoj kev saib xyuas dej hiav txwv tritium ntawm ntug dej hiav txwv tuaj yeem nkag siab cov kev hloov pauv hauv Marine ib puag ncig thiab coj kev nyab xeeb ntawm Marine ecological ib puag ncig.
Raws li lub teb chaws tseem ceeb nyob ze Nyiv, kev saib xyuas biorioactivity ntawm cov nqaij nruab deg kuj tseem ceeb heev los tiv thaiv tib neeg kev noj qab haus huv thiab ib puag ncig ecological.
Ua ntej, cov nqaij nruab deg muaj cov khoom noj muaj txiaj ntsig zoo thiab kev lag luam xav tau.Txawm li cas los xij, vim muaj cov pa phem hauv Marine thiab muaj cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ntawm cov nqaij nruab deg tuaj yeem dhau tus qauv, ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv.Yog li ntawd, kev soj ntsuam cov qib ntawm cov xov tooj cua ntawm Suav cov nqaij nruab deg tuaj yeem ua kom cov zaub mov muaj kev nyab xeeb ntawm cov neeg siv khoom.
Qhov thib ob, dej hiav txwv yog ib feem tseem ceeb ntawm lub ntiaj teb ecological ib puag ncig.Kev puas tsuaj ntawm cov khoom siv hluav taws xob rau Marine ecological ib puag ncig tsis tuaj yeem tsis quav ntsej.Kev soj ntsuam cov xov tooj cua ntawm cov nqaij nruab deg Suav tuaj yeem tsis tsuas yog tiv thaiv kev noj qab haus huv ntawm tib neeg lub cev, tab sis kuj tseem pab kom nkag siab txog kev ua qias tuaj ntawm Marine ecological ib puag ncig, thiab muab kev tshawb fawb txog kev tiv thaiv ib puag ncig.
Nyob rau hauv luv luv, qhov tseem ceeb ntawm kev saib xyuas cov nqaij nruab deg lom hluav taws xob hauv Suav teb tom qab tso dej pov tseg los ntawm Nyiv yog qhov tseeb ntawm nws tus kheej.Peb yuav tsum tau txais kev saib xyuas kev tshawb fawb thiab ua tau zoo txhais tau tias txhawm rau txhim kho qhov zoo thiab kev saib xyuas kev nyab xeeb ntawm cov nqaij nruab deg kom ntseeg tau tias tib neeg lub neej muaj kev nyab xeeb thiab noj qab haus huv.
Peb lub tuam txhab tau muab rau koj nrog cov txheej txheem saib xyuas cov dej hiav txwv thiab cov nqaij nruab deg, suav nrog cov qauv, cov qauv kev npaj thiab kev soj ntsuam cov kauj ruam ntawm cov dej hiav txwv thiab cov nqaij nruab deg, thiab muaj cov cuab yeej siv tau pom zoo.
Kev sim cov kauj ruam rau tritium hauv dej:
1. Kev kuaj xyuas teb;
2. Distillation thiab lwm yam kev tshem tawm ntawm ions;
3. Raws li HJ1126-2020 "Kev soj ntsuam txoj kev ntawm tritium hauv dej", siv cov txheej txheem electrolytic, nrog rau tritium electrolytic concentration ntsuas;
4. Cov kua dej Sintillation tau ntxiv thiab ntsuas siv lub ntsuas hluav taws xob ua kua.
Los ntawm cov txheej txheem no, tritium radioactivity hauv dej hiav txwv tuaj yeem raug txiav txim thiab txheeb xyuas.
Txheeb xyuas cov kauj ruam rau tritium thiab carbon 14 hauv cov nqaij nruab deg:
1. Qauv;
2. Txiav / txiav daim;
3. Lyophiliser lyophilization (lyophilized dej khaws cia ua ke rau kev kuaj pom, kuj tseem muaj tritium!);
4. Sib tsoo tshuab sib tsoo;
5. Siv cov khoom siv organic tritium carbon sampling los rho cov xov tooj cua tritium thiab carbon-14;
6. Triitium yog muab rho tawm hauv daim ntawv ntawm cov dej catalytic;
7. Cov pa roj carbon dioxide yog muab rho tawm hauv daim ntawv catalytic ntawm carbon dioxide thiab absorbed los ntawm sodium hydroxide;
8. Cov khoom siv hluav taws xob rho tawm tau muab ntxiv rau hauv cov kua dej scintillation thiab ntsuas siv lub ntsuas hluav taws xob ua kua.
Tom qab cov txheej txheem no, tritium thiab carbon radioactivity hauv cov nqaij nruab deg tuaj yeem raug txiav txim thiab tshuaj xyuas.
