Na1 PM muna Nyamavhuvhu 24,2023, hurumende yeJapan yakafuratira kupokana kwakasimba uye kushorwa kwenharaunda dzepasirese uye unilaterally yakamanikidza kubuda kwemvura ine tsvina kubva mutsaona yenyukireya yeFukushima.Zvakaitwa neJapan kuendesa njodzi kupasirese, kuwedzera marwadzo kuzvizvarwa zvinotevera zvevanhu, kuve kukuvadzwa kwezvakatipoteredza uye musvibisi weMarine wepasirese, kutyora kodzero yehutano, budiriro uye nharaunda yenyika dzese, uye kutyora kwayo. mutoro wehunhu uye mutemo wepasi rose.Mutsara weJapan wemvura ine nyukireya yakasvibiswa ichashorwa nenyika dzepasirese kwenguva yakareba.Hurumende yeChina yagara ichiisa vanhu pamberi uye ichatora matanho anodiwa kuchengetedza chikafu uye hutano hwevanhu vekuChina.
Mushure mekubuda kwemvura yetsvina kubva kuJapan, huwandu hwetritium hunowanikwa munzvimbo yeMarine hunogona kuwedzera, izvo zvichave nemhedzisiro paMarine ecosystem.Senyika huru yegungwa, kutarisa kweChina kwemvura yegungwa tritium pamhenderekedzo yegungwa kunogona kubata panguva yakakodzera shanduko yenzvimbo yeMarine uye kuperekedza kuchengetedzwa kwenzvimbo yeMarine ecological.
Senyika yakakosha iri pedyo neJapan, kuongorora biorioactivity yezvokudya zvegungwa kwakakoshawo kuchengetedza hutano hwevanhu uye nharaunda.
Chekutanga, chikafu chemugungwa chine hutano hwepamusoro uye kudiwa kwemusika.Nekudaro, nekuda kwekusvibiswa kweMarine uye kuvapo kwezvinhu zvine radioactive, huwandu hwemwaranzi hwemugungwa hunogona kudarika mwero, zvichiunza njodzi inogona kukuvadza hutano hwevanhu.Naizvozvo, kutarisa mwero weradioactivity yeChinese chikafu chegungwa chinogona kuve nechokwadi chekuchengetedza chikafu chevatengi.
Chechipiri, gungwa chikamu chakakosha chemhoteredzo yepasi rose.Kukuvadza kwezvinhu zvine radioactive kuMarine ecological environment hakugone kufuratirwa.Kutarisisa mwero weradioactivity weChinese chikafu chemugungwa hakungogone kuchengetedza hutano hwemiviri yevanhu, asi zvakare kubatsira kunzwisisa mamiriro ekusvibiswa kweMarine ecological environment, uye kupa hwaro hwesainzi hwekuchengetedza kwezvakatipoteredza.
Muchidimbu, kukosha kwekutarisa seafood biological radioactivity muChina mushure mekubuda kwetsvina kubva kuJapan kunozviratidza.Tinofanira kutora nzira dzesainzi uye dzinoshanda dzekutarisa kusimbisa kunaka uye kuchengetedzwa kwekutarisa kwekudya kwegungwa kuti tive nechokwadi chekuchengetedza hupenyu hwevanhu uye hutano.
Kambani yedu yakupa iwe seti yakazara yekutarisa zvirongwa zvemvura yegungwa uye yegungwa, kusanganisira sampling, sampu yekugadzirira uye yekutarisa matanho emvura yegungwa uye yegungwa, uye ine inoenderana inokurudzirwa zviridzwa.
Kuedza matanho e tritium mumvura:
1. Sampling yemumunda;
2. Distillation nedzimwe nzira dzekubvisa ions;
3. Maererano neHJ1126-2020 "Kuongorora nzira ye tritium muMvura", uchishandisa nzira ye electrolytic, ine tritium electrolytic concentration instrument;
4. Sintillation fluid yakawedzerwa uye kuyerwa pachishandiswa liquid scintillation counter.
Kuburikidza nemaitiro aya, iyo tritium radioactivity mumvura yegungwa inogona kutongwa uye kuongororwa.
Matanho ekucherekedza etritium uye kabhoni 14 mune zvegungwa:
1. Muenzaniso;
2. Cheka / cheka zvidimbu;
3. Lyophiliser lyophilization (mvura yakaomeswa yakachengetwa pamwe chete kuti ionekwe, ichavawo ne tritium!）;
4. Kukuya muchina;
5. Kushandisa organic tritium carbon sampling device kubvisa radioactive tritium uye carbon-14;
6. Triitium inotorwa nenzira yemvura inokonzeresa;
7. Carbon inobudiswa mu catalytic form of carbon dioxide uye inobatwa ne sodium hydroxide;
8. Yakabviswa radioactive zvinhu yakawedzerwa kune scintillation fluid uye kuyerwa uchishandisa liquid scintillation counter.
Mushure mekuita uku, iyo tritium uye kabhoni radioactivity mune zvegungwa zvinogona kutongwa uye kuongororwa.
Zvishandiso zvinoenderana
