Tsis - ionizing (los yog tsis yog - ionizing ) hluav taws xob hais txog txhua yam ntawm hluav taws xob hluav taws xob uas tsis nqa lub zog txaus ib quantum (photon zog) rau ua ionize atoms los yog molecules-uas yog, kom tshem tawm cov electron los ntawm lub atom los yog molecule.
Ib sab ntawm qhov no, puas yog cov hluav taws xob tsis zoo ionizing rau tib neeg?
Tsis - ionizing tawg yog qhov qis zog hluav taws xob uas tsis muaj zog txaus rau ua ionize atom los yog molecules. Nws nyob ntawm qhov kawg ntawm cov electromagnetic spectrum. Txawm hais tias tsawg dua txaus ntshai tshaj ionizing tawg , overexposure rau tsis yog - ionizing tawg tuaj yeem ua rau muaj teeb meem kev noj qab haus huv.
Ib yam nkaus, puas tuaj yeem tsis tawg hluav taws xob ua kom puas DNA? Lawv, nrog rau qee lub zog UV siab dua hluav taws xob , e npe ionizing tawg , uas txhais tau tias lawv muaj lub zog txaus los tshem tawm lub tshuab hluav taws xob los ntawm ( ua ionize ) atom los yog molecule. Qhov no tuaj yeem ua puas cov DNA sab hauv ntawm cov cell, uas tau ua rau mob qog noj ntshav. Nws yog ib yam ntawm tsis yog - ionizing tawg.
Ua li no, puas yog hluav taws xob hluav taws xob ionizing?
Ionizing hluav taws xob ( ionizing hluav taws xob ) yog hluav taws xob , taug kev raws li cov khoom me me lossis hluav taws xob yoj, uas nqa lub zog txaus los tshem cov electrons los ntawm atoms lossis molecules, yog li ionizing lawv.
Dab tsi yog non-ionizing hluav taws xob vs ionizing?
Hluav taws xob yog cais raws li yog tsis yog - ionizing los yog ionizing . Tsis - ionizing tawg ntev dua nthwv dej/qis zaus qis zog. Thaum ionizing tawg yog luv wavelength / siab zaus siab zog. Ionizing hluav taws xob muaj lub zog txaus los tsim cov ions hauv cov teeb meem ntawm qib molecular.

Thaum lub sijhawm koj nyob, koj yuav tsum tau zaum rau ntau qhov kev xeem ua los ntawm American Boardof Radiology. Qhov no suav nrog kev sau ntawv thiab kev hais lus ntawm rooj sab laj thiab kev tshuaj xyuas lub cev
Lub tshuab hluav taws xob X hluav taws xob ua haujlwm li cas?
Lub tshuab hluav taws xob X-ray feem ntau muaj lub raj xoo hluav taws xob los tsim cov duab hluav taws xob. Lub raj xoo hluav taws xob yog lub raj nqus yooj yim uas muaj cov cathode, uas coj cov dej ntawm cov hluav taws xob mus rau hauv lub tshuab nqus tsev, thiab anode, uas khaws cov hluav taws xob thiab ua los ntawm tungsten kom tshem tawm cov cua sov uas tsim los ntawm kev sib tsoo
