Puas ionizing hluav taws xob ua rau mob qog noj ntshav?
Radiation ntawm qee qhov wavelengths, hu ua ionizing hluav taws xob, muaj muaj zog txaus los ua puas DNAthiab ua rau mob qog noj ntshav. Ionizing hluav taws xob muaj xws li radon, x-rays, gamma rays, thiab lwm yam ntaub ntawv ntawm high-zog hluav taws xob.
hluav taws xob ua rau mob qog noj ntshav li cas?
Radiation tej zaum yuav disassemble atoms thiab ua rau DNA puas nyob rau hauv hlwb, ua rau muaj kev phiv loj heev, nrog rau mob qog noj ntshav. Lub teeb ultraviolet los ntawm lub hnub tuaj yeem ua rau cov tawv nqaij puas tsuaj thiab ua rau muaj kev pheej hmoo ntawm melanoma lossis lwm yam mob qog noj ntshav.
Ionizing hluav taws xob ua puas hlwb li cas?
Ionizing hluav taws xob ncaj qha cuam tshuam DNA qauv los ntawm kev ua kom DNA tawg, tshwj xeeb, DSBs Cov teebmeem thib ob yog cov cim ntawm cov pa oxygen reactive (ROS) uas oxidize proteins thiab lipids, thiab kuj induce ntau qhov kev puas tsuaj rau DNA, zoo li tiam ntawm qhov chaw abasic thiab ib qho strand so (SSB).
hom mob qog noj ntshav ua rau ionizing hluav taws xob ua rau?
Cov kab mob cuam tshuam nrog kev siv tshuaj ntau ntau suav nrog leukemia, mis, zais zis, plab, siab, ntsws, txoj hlab pas, zes qe menyuam, ntau yam myeloma, thiab mob qog noj ntshav.
