Tsuas yog ob qhov chaw tsim cov californium-252: lub Oak Ridge National Laboratory hauv Tebchaws Meskas, thiab Lub Tsev Haujlwm Tshawb Fawb ntawm Atomic Reactors hauv Dimitrovgrad, Russia.
gram ntawm californium-252 nqi npaum li cas?
Californium yog lwm cov khoom siv hluav taws xob, siv feem ntau hauv kev tshawb fawb thiab hauv cov cuab yeej siv hauv kev lag luam roj av. Ib gram ntawm californium-252 tuaj yeem raug nqi $ 27 lab ib gram, uas ua rau nws kim dua li lutetium, tab sis tsawg dua francium.
californium-252 ua li cas?
Californium-252 tsis tuaj yeem pom hauv qhov xwm txheej. Yog li ntawd, nws yog feem ntau synthesized nyob rau hauv lub chaw soj nstuam siv nyob rau hauv kev tshawb fawb thiab kev soj ntsuam kev khiav hauj lwm. Cf-252 yog tsim los ntawm kev siv curium; ib microgram ntawm cov khoom yog bombarded nrog alpha hais, uas ua rau tsim ntawm 5,000 atoms ntawm Cf-252.
Vim li cas california-252 thiaj li kim?
Californium-252 muaj nuj nqis vim nws cov cuab yeej ua lub zog neutron emitter, yog li, nws cov ntawv tshwj xeeb. Hauv cov tshuab hluav taws xob nuclear, nws yog siv los ua qhov chaw pib neutron thiab ua cov khoom siv hluav taws xob hauv nruab nrab hauv kev txheeb xyuas cov lej ntawm qee cov ntsiab lus (piv txwv li, kev tshuaj xyuas neutron ua kom muaj zog).
3 siv dab tsi rau california?
Californium yog lub zog neutron emitter heev. Nws yog siv nyob rau hauv portable hlau ntes, txhawm rau txheeb xyuas cov nyiaj kub thiab nyiaj, txhawm rau txheeb xyuas dej thiabcov roj txheej hauv cov roj qhov dej thiab txhawm rau kuaj cov hlau qaug zog thiab kev ntxhov siab hauv aeroplanes.
