Lub lim tiam dhau los, IAEA pom muaj hluav taws xob ntau tshaj nws cov qauv kev nyab xeeb hauv ib lub zos 40 mais ntawm Fukushima. Nws pom zoo tias Nyij Pooj txuas ntxiv thaj chaw muaj kev phom sij tab sis tsis tau hais ntau npaum li cas. Lub caij no, Tebchaws Asmeskas, Tebchaws Askiv, thiab Canada tau pom zoo tias nws cov neeg nyob hauv tebchaws tau ua tiav 80km ua deb ntawm Fukushima.
Ntawm no, hluav taws xob kis tau mus deb npaum li cas?
Kev tuag yog qhov muaj feem ntau thiab cov hluav taws xob lom yuav luag yog qhov tseeb yog tias ib tus raug ntes nyob rau hauv qhov qhib tsis muaj struts lossis lub tsev npog qhov cuam tshuam nyob rau hauv ib lub vojvoog ntawm 0-3 km los ntawm 1 megaton airburst, thiab 50% txoj kev tuag ntawm lub moj tej tawg txuas ntxiv mus. rau ~ 8km ua los ntawm tib 1 megaton atmospheric tawg.
Tsis tas li ntawd, hluav taws xob tuaj yeem mus deb npaum li cas los ntawm nuclear fais fab nroj tsuag? Lub chaw tsim hluav taws xob hluav taws xob ua haujlwm tsim hluav taws xob thiab cov kua dej me me, nrog rau cov hluav taws xob ncaj qha me me. Yog koj nyob hauv 50 mij ntawm ib lub tuam txhab hluav taws xob nuclear, koj yuav tau txais qhov nruab nrab hluav taws xob ntau li ntawm 0.01 millirem ib xyoos twg.
Ib yam li ntawd, puas yog hluav taws xob los ntawm Fukushima mus txog Asmeskas?
Fukushima hluav taws xob muaj mus txog U. S . ntug dej. Thawj thawj zaug, seaborne hluav taws xob los ntawm Nyiv Fukushima kev puas tsuaj nuclear tau raug kuaj pom ntawm ntug dej hiav txwv sab hnub poob ntawm Tebchaws Meskas. Vim tias nws lub neej ib nrab luv, cesium-134 tuaj yeem tsuas yog los ntawm Fukushima.
Puas yog Chernobyl phem dua Fukushima?
Qee cov kws tshawb fawb hais Fukushima yog phem dua tshaj li xyoo 1986 Chernobyl kev huam yuaj, uas nws qhia txog qib siab tshaj plaws-7 qhov ntsuas ntawm qhov swb ntawm kev puas tsuaj nuclear.
