Uhlelo lokutholwa lulonke lwe-tritium emanzini ne-tritium carbon ku-biology

Ngo-1 PM ngo-Agasti 24, 2023, uhulumeni waseJapan akazange akunake ukungabaza okunamandla nokuphikiswa komphakathi wamazwe omhlaba futhi waphoqelela ukukhishwa kwamanzi angcolile engozini yenuzi yaseFukushima.Okwenziwe yiJapan ukudlulisa izingozi emhlabeni, ukwelula ubuhlungu ezizukulwaneni ezizayo zesintu, kube umonakalo wendawo ezungezile kanye nomngcolisi wasolwandle womhlaba wonke, kwephule ilungelo lezempilo, ukuthuthukiswa kanye nemvelo yawo wonke amazwe, futhi kwephule umthetho wayo. isibopho sokuziphatha kanye nomthetho wamazwe ngamazwe.Uhide lwaseJapan lwamanzi angcolile enuzi luzolahlwa umphakathi wamazwe ngamazwe isikhathi eside.Uhulumeni waseShayina uhlale ebeka abantu phambili futhi uzothatha zonke izinyathelo ezifanele ukuvikela ukuphepha kokudla kanye nempilo yabantu baseChina.

Ngemva kokukhishwa kwamanzi angcolile avela e-Japan, inani le-tritium elitholakala endaweni yasolwandle lingase lenyuke, elizoba nomthelela ku-ecosystem yasolwandle.Njengezwe elikhulu lasolwandle, ukuqapha kweShayina i-tritium yamanzi olwandle ogwini kungakwazi ukuqonda izinguquko endaweni yasolwandle ngesikhathi esifanele futhi kuphelezele ukuphepha kwemvelo yasolwandle.

Njengezwe elibalulekile eliseduze ne-Japan, ukuqapha i-biorioactivity yezilwane zasolwandle nakho kubaluleke kakhulu ukuvikela impilo yabantu nendawo ezungezile.

Okokuqala, ukudla kwasolwandle kunenani eliphezulu lokudla okunempilo kanye nesidingo semakethe.Nokho, ngenxa yokunukubezeka kwasolwandle kanye nokuba khona kwezinto ezikhipha imisebe, amazinga emisebe yezilwane zasolwandle angase eqe izinga, kube usongo olukhulu empilweni yomuntu.Ngakho-ke, ukuqapha izinga le-radioactivity yezilwane zasolwandle zaseShayina kungaqinisekisa ukuphepha kokudla kwabathengi.

Okwesibili, ulwandle luyingxenye ebalulekile yemvelo yomhlaba wonke.Ukulimala kwezinto ezikhipha imisebe endaweni yemvelo yasolwandle akunakushaywa indiva.Ukuqapha izinga le-radioactivity yezilwane zasolwandle zaseShayina akukwazi nje ukuvikela impilo yemizimba yabantu, kodwa futhi kusiza ukuqonda isimo sokungcoliswa kwemvelo yasolwandle, futhi kunikeze isisekelo sesayensi sokuvikelwa kwemvelo.

Ngamafuphi, ukubaluleka kokuqapha i-seafood biological radioactivity e-China ngemva kokukhishwa kwamanzi angcolile avela e-Japan kuyabonakala.Kufanele sisebenzise izindlela zokuqapha zesayensi nezisebenzayo ukuze siqinise izinga nokuqapha kokuphepha kwezilwane zasolwandle ukuze siqinisekise ukuphepha nempilo yabantu.

Inkampani yethu ikunikeze isethi ephelele yezinhlelo zokuqapha amanzi olwandle nezilwane zasolwandle, okuhlanganisa ukusampula, ukulungiswa kwesampula kanye nezinyathelo zokuqapha amanzi olwandle nezilwane zasolwandle, futhi inamathuluzi ahambisanayo anconyiwe.

Izinyathelo zokuhlola i-tritium emanzini:

1. Ukusampula kwenkundla;
2. I-distillation nezinye izindlela zokukhipha ama-ion;
3. Ngokusho kwe-HJ1126-2020 "Indlela yokuhlaziya ye-tritium emanzini", kusetshenziswa indlela ye-electrolytic, ne-tritium electrolytic concentration;
4. Uketshezi lwe-sintillation lwengezwe futhi kukalwa kusetshenziswa ikhawunta ye-liquid scintillation.

Ngale nqubo, i-tritium radioactivity emanzini olwandle ingahlulelwa futhi ihlaziywe.

Izinyathelo zokutholwa kwe-tritium ne-carbon 14 ekudleni kwasolwandle:

1. Isampula;
2. Sika / usike izingcezu;
3. I-Lyophiliser lyophilization (amanzi a-lyophilized agcinwe ndawonye ukuze abonwe, futhi azoqukatha i-tritium!);
4. Umshini wokugaya umshini wokugaya;
5. Ukusebenzisa idivayisi yesampula ye-tritium carbon ukuze kukhishwe i-tritium enemisebe ne-carbon-14;
6. I-Triitium ikhishwa ngendlela yamanzi e-catalytic;
7. Ikhabhoni ikhishwa ngendlela ye-catalytic ye-carbon dioxide futhi imuncwe yi-sodium hydroxide;
8. Impahla ekhipha imisebe ekhishiwe yengezwa kuketshezi lwe-scintillation futhi kukalwa kusetshenziswa ikhawunta ye-liquid scintillation.

Ngemuva kwale nqubo, i-tritium ne-carbon radioactivity ekudleni kwasolwandle ingahlulelwa futhi ihlaziywe.
