Nge-24 ka-Agasti, iJapan yavula ukukhutshwa kwamanzi amdaka angcoliswe yingozi yenyukliya yaseFukushima kuLwandlekazi lwePasifiki.Okwangoku, ngokusekelwe kwidatha yoluntu ye-TEPCO ngoJuni 2023, ugutyulo olulungiselelwe ukukhupha ikakhulu luqukethe: umsebenzi we-H-3 malunga ne-1.4 x10⁵Bq / L;umsebenzi we-C-14 yi-14 Bq / L;I-129 yi-2 Bq / L;umsebenzi we-Co-60, Sr-90, Y-90, Tc-99, Sb-125, Te-125m kunye ne-Cs-137 yi-0.1-1 Bq / L. Kulo mba, asigxininisi kuphela kwi-tritium amanzi amdaka enyukliya, kodwa nakwimingcipheko enokubakho yezinye iiradionuclides.I-TepCO idize kuphela i-α iyonke kunye ne-β iyonke idatha ye-radioactive yamanzi angcolisekileyo, kwaye ayizange ichaze idatha yoxinaniso yeenuclides ze-ultra-uranium ezinetyhefu kakhulu njenge-Np-237, Pu-239, Pu-240, Am-240, Am- 241, Am-243 kunye ne-Cm-242, ekwayenye yeengozi ezingundoqo zokhuseleko lokukhutshelwa kwamanzi angcolisekileyo enyukliya elwandle.
Ungcoliseko lwemitha yokusingqongileyo lungcoliseko olufihlakeleyo, xa luvelisiwe luya kuba nempembelelo embi kubahlali abasingqongileyo.Ukongeza, ukuba i-biological okanye i-media media ejikeleze umthombo we-radioactive ingcolisekile yi-radionuclide, inokudluliselwa ukusuka kwinqanaba eliphantsi ukuya kwinqanaba eliphezulu ngekhonkco lokutya kwaye iphuculwe ngokuqhubekayo kwinkqubo yosulelo.Nje ukuba ezi zinto zingcolisa iradioactive zingene emzimbeni womntu ngokutya, zinokuqokelelana emzimbeni womntu, ezinokuba nefuthe kwimpilo yabantu.
Ukuze kuncitshiswe okanye kuthintelwe ubungozi bokuvezwa ngemitha eluntwini kunye nokukhusela impilo yoluntu ukuya kuthi ga kwinqanaba eliphezulu, "iMigangatho yoKhuseleko oluSiseko lwaMazwe ngaMazwe loKhuseleko lweRadiation kunye noKhuseleko lweMithombo yeRadiation" imisela ukuba abasemagunyeni abanobuchule benze inqanaba lereferensi yeradionuclides ekutyeni. .
E-China, imigangatho efanelekileyo iye yaqulunqwa ukuze kufunyanwe ii-radionuclids ezininzi eziqhelekileyo.Imigangatho yokufunyanwa kwezinto ezinomsakazo ekutyeni ziquka i-GB 14883.1 ~ 10- -2016 "uMgangatho weSizwe woKhuseleko lokuTya: Ukumiselwa kwezinto ze-radioactive kuKutya" kunye ne-GB 8538- -
I-2022 "uMgangatho weSizwe woKhuseleko lokuTya ukusela amanzi amaminerali endalo", i-GB / T 5750.13- -2006 "I-Radioactive Index yeendlela zokuHlola eziMgangatho zaManzi okusela", SN / T 4889- -2017 "Ukumiselwa kwe-γ i-Radionuclide kwi-Export High-Salt Food ", WS / T 234- -2002 "Umlinganiselo weMicimbi yeRadioactive kwi-Food-241", njl.
