Ma ʻAukake 24, ua wehe ʻo Iapana i ka hoʻokuʻu ʻana i ka wai ʻino i hoʻohaumia ʻia e ka ulia nuklea Fukushima i ka Moana Pākīpika.I kēia manawa, e pili ana i ka ʻikepili lehulehu o TEPCO i Iune 2023, ʻo ka wai i hoʻomākaukau ʻia no ka hoʻokuʻu ʻana ka mea nui: ʻo ka hana a H-3 ma kahi o 1.4 x10⁵Bq / L;ʻO ka hana o C-14 he 14 Bq / L;ʻO I-129 ka 2 Bq / L;ʻO ka hana a Co-60, Sr-90, Y-90, Tc-99, Sb-125, Te-125m a me Cs-137 he 0.1-1 Bq / L. Ma kēiaʻano,ʻaʻole mākou e nānā wale i ka tritium i loko. ka wai ʻōpala nuklea, akā ma luna o nā pilikia o nā radionuclides ʻē aʻe.Ua hōʻike wale ʻo TepCO i ka ʻikepili hana radioactive α a me β a pau o ka wai i hoʻohaumia ʻia, a ʻaʻole i hōʻike i ka ʻikepili koʻikoʻi o nā nuclides ultra-uranium ʻona loa e like me Np-237, Pu-239, Pu-240, Am-240, Am- 241, Am-243 a me Cm-242, ʻo ia kekahi o nā pilikia palekana koʻikoʻi no ka hoʻokuʻu ʻia ʻana o ka wai i hoʻohaumia ʻia i loko o ke kai.
ʻO ka pollution radiation kaiapuni kahi haumia huna, ke hana ʻia e loaʻa kahi hopena maikaʻi ʻole i nā kamaʻāina a puni.Eia kekahi, inā hoʻohaumia ʻia nā mea olaola a i ʻole nā mea hoʻolaha a puni ke kumu radioactive e ka radionuclide, hiki ke lawe ʻia mai ka pae haʻahaʻa a i ke kiʻekiʻe ma o ke kaulahao meaʻai a hoʻonui mau ʻia i ke kaʻina hana.Ke komo kēia mau mea hoʻohaumia radioactive i ke kino o ke kanaka ma o ka meaʻai, hiki iā lākou ke hōʻiliʻili i loko o ke kino o ke kanaka, a he hopena paha ia i ke olakino kanaka.
I mea e hōʻemi ai a pale aku paha i ka pōʻino o ka hoʻolaha ʻana i ka radiation i ka lehulehu a pale i ke olakino ākea a hiki i ka palena kiʻekiʻe loa, ʻo ka "International Basic Safety Standards for Radiation Protection and Radiation Source Safety" e kuhikuhi ana i nā mana kūpono e hoʻokumu i ka pae kuhikuhi no nā radionuclides i ka meaʻai. .
Ma Kina, ua hoʻokumu ʻia nā kūlana kūpono no ka ʻike ʻana i kekahi mau radionuclids maʻamau.ʻO nā maʻamau no ka ʻike ʻana i nā mea radioactive i loko o ka meaʻai me GB 14883.1~10- -2016 "National Standard for Food Safety: Determination of radioactive substances in Food" a me GB 8538- -
