I le aso 24 o Aokuso, na tatalaina ai e Iapani le lafoaia o le suavai leaga na afaina i le faalavelave faaniukilia a Fukushima i le Vasa Pasefika.I le taimi nei, e tusa ai ma faʻamatalaga lautele a le TEPCO ia Iuni 2023, o le lapisi ua saunia e lafoai e masani lava ona aofia ai: o le gaioiga a le H-3 e tusa ma le 1.4 x10⁵Bq / L;o le gaioiga o le C-14 o le 14 Bq / L;I-129 o le 2 Bq / L;o le gaioiga a Co-60, Sr-90, Y-90, Tc-99, Sb-125, Te-125m ma Cs-137 o le 0.1-1 Bq / L. I lenei tulaga, tatou te taulai atu e le gata i le tritium i totonu. vai otaota faaniukilia, ae fa'apea fo'i i luga o a'afiaga e ono a'afia ai isi radionuclides.Na'o le TepCO na fa'aalia le aofa'i o le α ma le aofa'i o fa'amatalaga fa'aeletonika β o vai fa'aleagaina, ma e le'i fa'ailoaina fa'amaumauga fa'amauina o nuclides ultra-uranium sili ona oona pei ole Np-237, Pu-239, Pu-240, Am-240, Am- 241, Am-243 ma le Cm-242, o se tasi foi lea o lamatiaga autu mo le saogalemu mo le lafoaia o vai faaniukilia i le sami.
O le fa'aleagaina o le radiation o le fa'aleagaina o le si'osi'omaga ose filogia natia, a maua loa o le a iai se a'afiaga leaga i tagata o lo'o si'omia.E le gata i lea, afai o le meaola faʻasalalau poʻo le faʻasalalauga faʻasalalau i luga o le alaleo eletise e afaina i le radionuclide, e mafai ona faʻasalalau mai le tulaga maualalo i le maualuga e ala i le filifili meaʻai ma faʻaauau pea ona faʻatamaoaigaina i le faagasologa o felauaiga.O le taimi lava e ulu atu ai nei mea eleelea i totonu o le tino o le tagata e ala i meaai, e mafai ona faaputuputu i totonu o le tino o le tagata, e ono afaina ai le soifua maloloina o le tagata.
Ina ia faʻaitiitia pe aloese mai le afaina o le faʻaalia o le radiation i tagata lautele ma puipuia le soifua maloloina lautele i le maualuga maualuga, o le "International Basic Safety Standards for Radiation Protection and Radiation Source Safety" o loʻo faʻamaonia ai e tatau i pulega faʻapitoa ona faʻatulagaina le maualuga o faʻamatalaga mo radionuclides i meaʻai. .
I Saina, ua faʻatulagaina tulaga talafeagai mo le suʻeina o le tele o radionuclids masani.O faʻataʻitaʻiga mo le suʻesuʻeina o mea faʻasalalau i meaʻai e aofia ai GB 14883.1~10- -2016 "National Standard for Food Safety: Suʻesuʻeina o mea faʻasalalau i meaʻai" ma GB 8538- -
2022 "National Standard for Food Safety Infusion Natural Mineral Water", GB / T 5750.13- -2006 "Radioactive Index for Standard Inspection Methods for Infusion Water", SN / T 4889- -2017 "Determination of γ Radionuclide in Export High-salt Food ", WS / T 234- -2002 "Suʻeina o Mea Faʻasao Leitio i Meaʻai-241", ma isi.
