Ionizing hluav taws xob ntau npaum li cas yog teeb meem?
Muaj kev pheej hmoo tseem ceeb hauv thaj tsam li 0 - 100 millisievert thiab qhov kev pheej hmoo muaj txiaj ntsig zoo rau cov koob tshuaj tsawg li 50 - 100 millisieverts. Qhov kev pheej hmoo ntawm qhov nruab nrab ntawm txhua lub hnub nyoog thiab hom mob qog noj ntshav yog hais txog 1 ntawm 10, 000 ib millisievert.
Puas yog hluav taws xob ua rau koj lub neej luv?
"Kev faib cov hlwb sai sai, xws li cov qog nqaij hlav cancer, yog cuam tshuam ntau dua los ntawm kev kho hluav taws xob ntau dua li cov hlwb ib txwm muaj. Feem ntau cov txheej txheem me me thiab feem ntau tsis ua teeb meem mus sij hawm ntev uas cuam tshuam rau lub neej zoo. "
5 siv hluav taws xob dab tsi?
Hnub no, kom muaj txiaj ntsig rau tib neeg, hluav taws xob tau siv hauv tshuaj, kev kawm, thiab kev lag luam, nrog rau kev tsim hluav taws xob. Tsis tas li ntawd, hluav taws xob muaj txiaj ntsig zoo hauv thaj chaw xws li kev ua liaj ua teb, archaeology (carbon dating), kev tshawb nrhiav chaw, kev cai lij choj, geology (xws li mining), thiab ntau lwm yam.
