Kev tiv thaiv hluav taws xob yeej ib txwm yog ib feem tseem ceeb ntawm kev ua haujlwm nuclear.
Tau ntau xyoo lawm, nuclear fais fab nroj tsuag, kev tshawb fawb reactors, roj- lub voj voog cov chaw, thiab cov chaw ua cov khoom siv hluav taws xob tau nqis peev ntau rau hauv cov hluav taws xob saib xyuas hluav taws xob tsim los tiv thaiv cov neeg ua haujlwm thiab xyuas kom muaj kev ua raws cai.
Cov neeg feem coob koom nrog kev saib xyuas hluav taws xob nrog gamma rays thiab tswj kev sib kis. Txawm li cas los xij nyob rau hauv cov chaw niaj hnub nuclear, lwm hom hluav taws xob nthuav tawm qhov kev sib tw tshwj xeeb uas feem ntau tau txais kev saib xyuas pej xeem tsawg:
Neutron hluav taws xob.
Tsis zoo li gamma hluav taws xob, cov neutrons yog qhov nyuaj dua los kuaj pom, nyuaj rau kev tiv thaiv, thiab tuaj yeem ua rau muaj txiaj ntsig zoo rau kev ua haujlwm hluav taws xob hauv qee qhov chaw nuclear.
Raws li cov chaw nuclear tau dhau los ua thev naus laus zis thiab ua haujlwm nyuaj, kev saib xyuas hluav taws xob neutron tau dhau los ua ib qho tseem ceeb ntxiv ntawm cov phiaj xwm tiv thaiv hluav taws xob niaj hnub no.
Nkag siab txog Neutron Radiation
Neutrons yog cov khoom siv hluav taws xob uas tsis muaj hluav taws xob tso tawm thaum lub sij hawm nuclear fission thiab qee cov txheej txheem nuclear.
Vim tias cov neutrons tsis muaj hluav taws xob, lawv cuam tshuam nrog cov teeb meem txawv dua li alpha, beta, lossis gamma hluav taws xob.
Cov yam ntxwv no ua rau ob qho kev sib tw tseem ceeb:
Neutrons tuaj yeem nkag mus rau hauv cov ntaub ntawv uas txawv ntawm gamma tawg.
