Xav txog qhov no, lub xov tooj cua twg yog qhov txaus ntshai tshaj plaws rau tib neeg?

Gamma

Qhov thib ob, alpha hluav taws xob cuam tshuam rau lub cev li cas? Alpha hais tsis muaj lub zog kom nkag mus txawm tias txheej txheej ntawm daim tawv nqaij, yog li raug rau sab nraud lub cev tsis yog ib qho kev txhawj xeeb loj. Yog alpha - emitters yog nqus tau, nqos, los yog nkag mus rau hauv lub cev los ntawm kev txiav, lub alpha hais ua tau kev puas tsuaj cov ntaub so ntswg nyob.

Tib neeg kuj nug, alpha lossis beta hais puas txaus ntshai?

alpha hluav taws xob yog cov txaus ntshai tshaj plaws vim nws yooj yim absorbed los ntawm hlwb. beta thiab gamma hluav taws xob tsis yog li txaus ntshai vim tias lawv tsis tshua muaj peev xwm nqus tau los ntawm lub cell thiab feem ntau yuav dhau los ntawm nws.

Dab tsi yog qhov phom sij ntawm hluav taws xob?

Tshaj tawm rau qib siab heev ntawm hluav taws xob , xws li nyob ze rau qhov tawg atomic, tuaj yeem ua rau mob hnyav xws li tawv nqaij kub hnyiab thiab mob hnyav. hluav taws xob syndrome (" hluav taws xob mob").
