Dab tsi cov yam ntxwv ua high linear zog hloov ( LET ) hluav taws xob muaj thaum piv nrog tsawg - LET radiation ? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau dua ionizations hauv cov ntaub so ntswg, sai sai poob. zog.

Ntawm no, dab tsi yog linear zog hloov hauv hluav taws xob?

Hauv dosimetry, linear zog hloov (LET) yog tus nqi ntawm zog uas yog ionizing particle hloov tsheb mus rau cov khoom traversed ib unit nrug. Nws piav txog qhov kev txiav txim ntawm hluav taws xob rau hauv qhov teeb meem. Nws zoo ib yam rau lub zog retarding uas ua rau cov nqi ionizing particle taug kev los ntawm qhov teeb meem.

Tsis tas li ntawd, dab tsi yog qhov tseem ceeb ntawm kev hloov hluav taws xob linear? Radiobiology > Lub cev txheej txheem > Linear Zog Hloov [LEEJ] > Linear Zog Hloov [LET] LEEJ yog tus nqi ntawm zog pauv mus rau lub zos ib puag ncig nyob rau hauv daim ntawv ntawm ionizations thiab excitations. Yog li, LET qhia txog lub peev xwm rau kev lom neeg tseem ceeb kev puas tsuaj los ntawm hluav taws xob.

Tom qab ntawd, LET hluav taws xob tsawg yog dab tsi?

Hluav taws xob yog cais raws li qhov siab linear zog hloov (siab LET ) lub qis linear zog hloov ( qis LET ), raws li tus nqi ntawm lub zog nws hloov mus rau ib chav tsev txoj kev ntev nws mus. Alpha hluav taws xob yog siab LET ; beta thiab gamma hluav taws xob yog qis LET.

Dab tsi yog cia hauv xray?

Lub ntsiab txhais yog li ntawd LET yog ib qho kev ntsuas ntawm lub zog tswj kev ua haujlwm ntawm kev them nyiaj ionizing particle taug kev los ntawm cov teeb meem. Thiab lub zog hloov pauv, txhais tau hais tias ntau npaum li cas ntawm cov hluav taws xob hluav taws xob tau xa mus rau hauv cov khoom nws yuav dhau mus. Lub tswvyim no muaj feem xyuam rau X - ray piv rau lwm hom hluav taws xob.
