Suavai otaota faaniukilia ≠ otaota faaniukilia
Suavai otaota faaniukilia e masani lava ona faasino i le suavai lafoai mai fale eletise faaniukilia.Suavai otaota faaniukilia e masani lava ona aofia ai meafaigaluega autu ma meafaigaluega fesoasoani vai alavai, reactor vai lafoai, aemaise lava mo vai lapisi maualalo ma feololo.Suavai otaota faaniukilia E tusa lava pe a maeʻa le "faʻamamaina" togafitiga o vai otaota faaniukilia, o loʻo iai foʻi, carbon 14, drill 60, 90 ma isi mea faigata ona aveese atoa toega o mea faʻaola.E sili atu ona mata'utia le vai fa'aniukilia, ma ua fa'afefiloi e Iapani ia mea e lua.
O le a le tele o le vai ua afaina i Fukushima ua aafia ai i tatou?
E tusa ai ma le mataituina muamua o le faalavelave faaniukilia i Fukushima, pe a uma ona ulufale le vai ua faaleagaina i le gataifale o le gataifale, e muamua ona feaveaia e ala o le sami, ma o le a salalau atu i ogasami eseese, pe a ma le 240 aso talu ona ulufale mai i lo tatou sami.
Pe mo le gataifale, pe mo tagata soifua, e matua afaina lava.O le taimi lava e afaina ai i nei mea eleelea leitio, e mafai ona ulu saʻo i totonu o laʻau ma manu, mafua ai suiga i le faasologa o kenera, mafua ai faʻamaʻi ogaoga, e pei o le kanesa ma isi.I le taimi lava e tasi, o lona aʻafiaga i le isi augatupulaga e matua tele lava, o le sili ona faʻaogaina o aʻafiaga ogaoga ma faʻamaʻi faʻamaʻi o le tupulaga fou.
E fa'afefea ona su'esu'e fa'avevela o lo'o siomia ai?
E ui lava e le mafai ona vaʻaia ma paʻi i le faʻamalositino faaniukilia, ae o le mea moni i le ea, eleele, vai o le sami i totonu o le nofoaga feololo, pe afai e sili atu le tau o le radiation faaniukilia i le saogalemu, o le a afaina ai le tino o le tagata, manaʻo e vaʻai faaniukilia. fa'avevela, e mana'omia lou fa'aogaina o meafaigāluega fa'apolofesa: fa'amalama faaniukilia detector.
E fa'afefea ona galue se mea faigaluega fa'aola faaniukilia?
e iloa foi le mea faaniukilia le su'esu'eina o le elemene.Ose masini mo le su'eina o le radiation.
O le vaega autu o le meafaigaluega e iloa ai le radiation faaniukilia o le sensor.O le masini faʻaola faaniukilia e faʻavae i luga o le mitiia, faʻasalalau i tua poʻo le faʻafefe o le mea e fuaina.O isotopes leitio e tu'u ese ai ni vaega (po'o ave) ma se aofaiga o le malosi i le taimi o le pala, e aofia ai ave o le alpha, beta, gamma, ma neutron.O lana galuega o le fa'aliliuina lea o fa'amatalaga fa'aletino eseese, vaila'au ma isi fa'amatalaga fesuisuia'i e mana'omia ona iloa i fa'ailoga eletise fua, ona pasi atu lea i le pu mo le fa'atatauina.
O a tupe meataalo e mana'omia mo su'esu'ega faaniukilia?
1. O le chip receiver o se tasi lea o vaega taua o le su'esu'eina o le radiation faaniukilia;O meataalo e 7 ADI
