Amanzi amdaka enyukliya ≠ ilindle lenyukliya
Amanzi amdaka eNyukliya ngokubanzi abhekisa kumanzi amdaka akhutshwa kwimizi-mveliso yamandla enyukliya.Amanzi amdaka eNyukliya ikakhulu abandakanya ezona zixhobo zingundoqo kunye nezixhobo ezincedisayo zokukhupha amanzi, amanzi alahlwayo kwireyitha, ikakhulu kumanzi amdaka aphantsi naphakathi anokusasazeka ngemitha.Amanzi amdaka eNyukliya Nasemva “kokucoca” ukucocwa kwamanzi amdaka enyukliya, ikwaqulathe, i-carbon 14, i-drill 60, 90 kunye nezinye ezinzima ukususa ngokupheleleyo iintsalela zemathiriyeli ye-radioactive.Amanzi angcolileyo enyukliya ayingozi ngakumbi, kwaye iJapan idibanisa ezi zimbini.
Angakanani amanzi angcolisekileyo aseFukushima asichaphazele?
Ngokohlolo lwangaphambili lwengozi yenyukliya yaseFukushima, emva kokuba amanzi angcolileyo enyukliya angene kwindawo yaseLwandle, iqala ukuthuthwa ngamaza olwandle, kwaye iya kusasazeka kwiilwandle ezahlukeneyo, malunga neentsuku ze-240 emva kokungena elwandle lwethu.
Nokuba yeyobomi baseLwandle, okanye yeyabantu, iyingozi kakhulu.Nje ukuba ingcoliswe zezi ngcoliseko zeradioactive, inokungena ngokuthe ngqo ngaphakathi kwizityalo nezilwanyana, ibangele iinguqu kulandelelwano lwemfuza, ibangele izifo ezinzulu, ezinjengomhlaza njalo njalo.Kwangaxeshanye, impembelelo yayo kwisizukulwana esilandelayo nayo inkulu kakhulu, eyona mpembelelo intuitive kukonakala okunzulu kunye nezifo zofuzo zesizukulwana esitsha.
Indlela yokufumanisa i-radiation ngeenxa zonke?
Nangona imitha yenyukliya ayinakubonwa kwaye ichukunyiswe, kodwa eneneni emoyeni, emhlabeni, emanzini olwandle kwindawo ephakathi, ukuba ixabiso lemitha yenyukliya lidlula uluhlu olukhuselekileyo, luya kubangela ingozi kumzimba womntu, ufuna ukubona inyukliya. ngemitha, kufuneka usebenzise izixhobo zobungcali: isitshingi semitha yenyukliya.
Sisebenza njani isixhobo semitha yenyukliya?
Isibonisi semitha yenyukliya saziwa ngokuba sisiqalelo sokubona inyukliya.Sisixhobo sokubona ukusasazeka kwemitha.
Elona candelo lingundoqo lesixhobo sokubona ukusasazeka kwemitha yenyukliya sisiva.Isivamvo semitha yenyukliya sisekwe ekufunxeni, ekusasazweni okanye kwi-ionizing excitation yento elinganisiweyo.Iisotophu ezisasazwa ngemitha zikhupha amasuntswana (okanye imitha) enomlinganiselo othile wamandla ngexesha lokubola, kuquka ialpha, ibeta, igamma, nemitha yeneutron.Umsebenzi wayo kukuguqula ulwazi olwahlukeneyo lomzimba, iikhemikhali kunye nolunye oluguquguqukayo olufuna ukubonwa kwiimpawu zombane ezinokulinganiswa, kwaye emva koko udlulisele kwi-chip ukubala.
Zeziphi iitshiphusi ezifunekayo kwizichongi zemitha yenyukliya?
1. Itshiphu yomamkeli yenye yezinto ezingundoqo eziyimfuneko kwisichopheli semitha yenyukliya;Nazi iitshiphusi ezisi-7 ze-ADI
