Electromagnetic Radiation vs Nuclear Radiation
hluav taws xob hluav taws xob thiab hluav taws xob hluav taws xob nuclear yog ob lub ntsiab lus sib tham hauv physics. Cov ntsiab lus no tau siv dav hauv kev lag luam xws li optics, xov tooj cua technology, kev sib txuas lus, kev tsim hluav taws xob, thiab ntau yam kev lag luam. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo hauv hluav taws xob hluav taws xob thiab hluav taws xob nuclear thiaj li ua tau zoo hauv cov haujlwm no. Hauv tsab xov xwm no, peb yuav tham txog dab tsi hluav taws xob hluav taws xob hluav taws xob thiab hluav taws xob hluav taws xob nuclear yog dab tsi, lawv cov lus txhais, lawv cov ntawv thov, qhov sib xws ntawm hluav taws xob hluav taws xob thiab hluav taws xob hluav taws xob nuclear, thiab thaum kawg qhov sib txawv ntawm hluav taws xob hluav taws xob thiab hluav taws xob nuclear.
Electromagnetic Radiation
hluav taws xob hluav taws xob, lossis feem ntau hu ua EM hluav taws xob, yog thawj zaug los ntawm James Clerk Maxwell. Qhov no tom qab tau lees paub los ntawm Heinrich Hertz uas ua tiav thawj EM nthwv dej. Maxwell tau muab cov qauv nthwv dej rau cov hluav taws xob thiab sib nqus nthwv dej thiab ua tiav qhov kev ntsuas ceev ntawm cov nthwv dej no. Txij li thaum lub nthwv dej no sib npaug rau qhov kev sim ntawm qhov ceev ntawm lub teeb, Maxwell kuj tau hais tias lub teeb yog, qhov tseeb, ib daim ntawv ntawm EM nthwv dej. Electromagnetic nthwv dej muaj ob qho tib si hluav taws xob thiab ib qho chaw sib nqus oscillating perpendicular rau ib leeg thiab perpendicular rau cov kev taw qhia ntawm yoj propagation. Txhua qhov hluav taws xob hluav taws xob muaj tib qhov kev tshaj tawm hauv lub tshuab nqus tsev. Qhov zaus ntawm electromagnetic yoj txiav txim siab lub zog khaws cia hauv nws. Tom qab ntawd nws tau pom tias siv quantum mechanics tias cov nthwv dej no yog, qhov tseeb, pob ntawv ntawm nthwv dej. Lub zog ntawm pob ntawv no nyob ntawm qhov zaus ntawm nthwv dej. Qhov no qhib lub teb ntawm nthwv dej - particle duality ntawm teeb meem. Tam sim no nws tuaj yeem pom tias hluav taws xob hluav taws xob tuaj yeem suav tias yog nthwv dej thiab hais. Ib yam khoom, uas tau muab tso rau hauv qhov kub thiab txias tshaj qhov xoom xoom, yuav tawm EM nthwv dej ntawm txhua lub wavelength. Lub zog uas qhov siab tshaj plaws ntawm cov photons tawm yog nyob ntawm qhov kub ntawm lub cev.
Nuclear Radiation
Ib qho tshuaj tiv thaiv nuclear yog cov tshuaj tiv thaiv uas cuam tshuam nrog cov nuclei ntawm atoms. Muaj ntau hom kev tawm tsam nuclear. Lub fusion nuclear yog ib qho tshuaj tiv thaiv qhov twg ob lossis ntau dua cov nuclei sib xyaw ua ke los tsim cov nucleus hnyav. Lub nuclear fission yog ib qho kev tshwm sim uas ib tug hnyav nucleus tawg mus rau hauv ob los yog ntau tshaj me me nuclei. Nuclear lwj yog qhov emission ntawm cov khoom me me los ntawm qhov hnyav, tsis ruaj khov. Nuclear cov tshuaj tiv thaiv tsis tas yuav txaus siab rau kev txuag ntawm huab hwm coj lossis kev txuag hluav taws xob tab sis kev txuag ntawm huab hwm coj-zog txaus siab. Nuclear hluav taws xob yog cov hluav taws xob hluav taws xob hluav taws xob tawm hauv cov kev cuam tshuam zoo li no. Feem ntau ntawm lub zog no yog tawm hauv X-ray thiab gamma ray cheeb tsam ntawm electromagnetic spectrum.
Dab tsi yog qhov txawv ntawm Electromagnetic thiab Nuclear Radiation?
• Nuclear hluav taws xob tsuas yog tawm hauv cov tshuaj tiv thaiv nuclear xwb tab sis hluav taws xob hluav taws xob tuaj yeem tawm hauv txhua qhov xwm txheej.
• Nuclear hluav taws xob yog hluav taws xob hluav taws xob uas tshwm sim hauv cov tshuaj tiv thaiv nuclear. Nuclear hluav taws xob feem ntau yog qhov nkag siab heev yog li tuaj yeem tsim kev phom sij heev, tab sis tsuas yog hluav taws xob hluav taws xob hluav taws xob muaj hluav taws xob muaj teeb meem xwb.
• Nuclear radiation mas muaj gamma rays thiab lwm yam high-zog electromagnetic rays nrog rau cov me me xws li electrons thiab neutrinos. Electromagnetic hluav taws xob tsuas muaj photons.
