Nyob ze ntawm cov hluav taws xob ultraviolet UV hluav taws xob siab tshaj 10 eV (wavelength luv dua 125 nm) yog suav tias yog ionizing. Txawm li cas los xij, tus so ntawm UV spectrum los ntawm 3.1 eV (400 nm) mus rau 10 eV, txawm hais tias technically non-ionizing, tuaj yeem tsim cov tshuaj tiv thaiv photochemical uas ua rau cov molecules puas tsuaj los ntawm lwm yam uas tsis yog cov cua sov yooj yim.
Dab tsi yog qhov tsawg kawg ntawm ionizing hluav taws xob?
EURATOM Cov Lus Qhia (1996): Ionizing Radiation: Kev hloov hluav taws xob hauv daim ntawv ntawm cov khoom lossis cov hluav taws xob hluav taws xob ntawm lub wavelength ntawm 100 nm lossis tsawg dua lossis ntau zaus ntawm 1.1015 Hz los yog muaj peev xwm ua tau ions ncaj qha lossis tsis ncaj.
Puas yog ionizing hluav taws xob ntau zaus?
Radiation muaj nyob thoob plaws ib spectrum los ntawm tsawg-zog (tsawg-frequency) hluav taws xob mus rau hnyav-zog (high-frequency) hluav taws xob. … Cov kab hluav taws xob no, nrog rau qee lub zog ntau dua UV hluav taws xob, yog hom hluav taws xob ionizing, uas txhais tau tias lawv muaj lub zog txaus los tshem tawm cov hluav taws xob los ntawm (ionize) ib qho atom.
Ntawm zaus hluav taws xob ua puas tsuaj?
Cov pov thawj tshawb fawb qhia tias mob qog noj ntshav tsis yog txuas nrog lub xov tooj ntawm tes hluav taws xob nkaus xwb thiab lwm yam kuj tseem tuaj yeem cuam tshuam rau nws txoj kev loj hlob. Feem ntau cov neeg siv xov tooj ntawm tes siv los ntawm cov xov tooj cua zaus hauv ntau li 300 MHz txog 3 GHz uas tuaj yeem ua rau tib neeg noj qab haus huv (1).
Dab tsi ntawm cov hluav taws xob hluav taws xob yog ionizing?
Nyobntau zaus ntawm EM hluav taws xob, suav nrog x-rays thiab gamma rays, yog hom hluav taws xob ionizing. Tsawg zaus hluav taws xob, muaj xws li ultraviolet (UV), infrared (IR), microwave (MW), Xov tooj cua zaus (RF), thiab tsis tshua muaj zaus (ELF) yog hom hluav taws xob tsis-ionizing.
