Nuclear wastewater ≠ nuclear dej phwj
Nuclear wastewater feem ntau yog hais txog cov dej khib nyiab tawm ntawm nuclear fais fab nroj tsuag.Nuclear wastewater feem ntau suav nrog cov cuab yeej tseem ceeb thiab cov cuab yeej pabcuam cov dej ntws tawm, cov dej tso tawm reactor, feem ntau yog rau cov dej khib nyiab tsawg thiab nruab nrab.Nuclear wastewater Txawm tias tom qab "filtration" kev kho cov dej khib nyiab nuclear, nws kuj muaj, carbon 14, laum 60, 90 thiab lwm yam nyuaj kom tshem tawm cov khoom siv hluav taws xob tag nrho.Nuclear contaminated dej yog txaus ntshai, thiab Nyiv conflates ob.
Fukushima dej paug tau cuam tshuam li cas rau peb?
Raws li kev soj ntsuam yav dhau los ntawm Fukushima nuclear kev sib tsoo, tom qab cov dej tsis huv nuclear nkag mus rau hauv Marine ib puag ncig, nws yog thawj zaug thauj los ntawm dej hiav txwv tam sim no, thiab yuav kis mus rau cov dej hiav txwv sib txawv, txog 240 hnub tom qab nkag mus rau hauv peb lub hiav txwv.
Txawm hais tias nws yog rau Marine lub neej, lossis rau tib neeg, nws muaj kev phom sij heev.Thaum kis tau los ntawm cov pa phem no, nws tuaj yeem nkag mus rau sab hauv ntawm cov nroj tsuag thiab tsiaj txhu, ua rau muaj kev hloov pauv hauv cov caj ces, ua rau muaj kab mob loj, xws li mob qog noj ntshav thiab lwm yam.Nyob rau tib lub sijhawm, nws qhov kev cuam tshuam rau cov tiam tom ntej kuj tseem loj heev, qhov cuam tshuam zoo tshaj plaws yog qhov loj deformities thiab cov kab mob caj ces ntawm cov tiam tshiab.
Yuav ua li cas thiaj nrhiav tau hluav taws xob nyob ib puag ncig?
Txawm hais tias cov hluav taws xob hluav taws xob tsis tuaj yeem pom thiab kov tau, tab sis qhov tseeb hauv huab cua, av, dej hiav txwv hauv qhov chaw nruab nrab, yog tias tus nqi hluav taws xob hluav taws xob ntau tshaj qhov kev nyab xeeb, nws yuav ua rau muaj kev phom sij rau tib neeg lub cev, xav pom nuclear. hluav taws xob, koj yuav tsum siv cov cuab yeej tshaj lij: nuclear hluav taws xob ntes.
Lub ntsuas hluav taws xob nuclear ua haujlwm li cas?
nuclear radiation detector tseem hu ua nuclear detection element.Nws yog ib qho khoom siv los kuaj xyuas hluav taws xob.
Lub hauv paus tseem ceeb ntawm cov cuab yeej ntsuas hluav taws xob nuclear yog lub sensor.Cov hluav taws xob hluav taws xob nuclear yog raws li qhov nqus, rov qab los yog ionizing excitation ntawm cov khoom ntsuas.Radioactive isotopes muab cov khoom (los yog rays) nrog ib tug npaum li cas ntawm lub zog thaum lub sij hawm lwj, xws li alpha, beta, gamma, thiab neutron rays.Nws txoj haujlwm yog los hloov ntau yam ntawm lub cev, tshuaj lom neeg thiab lwm yam ntaub ntawv sib txawv uas yuav tsum tau kuaj pom hauv cov teeb liab ntsuas hluav taws xob, thiab tom qab ntawd dhau mus rau lub nti rau kev suav.
Cov chips twg xav tau rau cov tshuab hluav taws xob hluav taws xob?
