Peb hais tias x-rays yog "ionizing," txhais tau hais tias lawv muaj peev xwm tshem tawm cov electrons ntawm atoms thiab molecules hauv qhov teeb meem uas lawv dhau mus. Kev ua ionizing tuaj yeem hloov cov molecules hauv cov hlwb ntawm peb lub cev. Qhov kev txiav txim ntawd yuav ua rau muaj kev phom sij (xws li mob qog noj ntshav).
Yuav ua li cas electromagnetic nthwv dej yog ionizing?
X-rays thiab gamma rays muaj lub zog txaus uas thaum muaj kev cuam tshuam nrog cov atoms, lawv tuaj yeem tshem tawm cov hluav taws xob thiab ua rau lub atom dhau los lossis ionized. Yog vim li cas peb xa mus rau cov no li ionizing hluav taws xob. Thaum neeg feem coob tham txog hluav taws xob, lawv hais txog hluav taws xob ionizing.
Yuav ua li cas electromagnetic yoj yog Ionising tshaj plaws?
Alpha particles muaj kwv yees li plaub npaug ntawm qhov loj ntawm proton lossis neutron thiab kwv yees li ~ 8,000 npaug ntawm qhov loj ntawm beta particle (Daim duab 5.4. 1). Vim tias qhov loj ntawm cov alpha particle, nws muaj lub zog ionizing siab tshaj plaws thiab muaj peev xwm ua rau cov ntaub so ntswg puas.
Yuav ua li cas hom EM yoj tsis yog ionizing?
Tsis yog-ionizing hluav taws xob tau piav qhia raws li cov kab hluav taws xob tsis muaj zog uas tsim los ntawm oscillating hluav taws xob thiab sib nqus teb ncig ntawm qhov ceev ntawm lub teeb. Tsis-ionizing hluav taws xob suav nrog cov spectrum ntawm ultraviolet (UV), pom lub teeb, infrared (IR), microwave (MW), xov tooj cua zaus (RF), thiab tsis tshua muaj zaus (ELF).
Puas yog xov tooj cua ionizing?
xov tooj cua zaus (RF) yog dab tsi? Radiofrequency (RF) hluav taws xob, uas suav nrog cov xov tooj cua thiab microwaves, yog nyob rau ntawm lub zog qis kawg ntawm electromagnetic spectrum. Nws yog hom tsis-ionizing hluav taws xobTsis yog-ionizing hluav taws xob tsis muaj lub zog txaus los tshem tawm cov hluav taws xob ntawm lub atom.
