LIS PHAJPuas yog thawj cov kev ua yeeb yam, txhuas yog qhov tseem ceeb tshaj plaws hlau, muaj ntau yam ntxwv tseem ceeb, nyuaj thiab tiv thaiv kev tiv thaiv kev ua haujlwm zoo. Nrog cov loj loj thiab ntom ntom, tsuas yog siv nyob rau hauv kev tsim cov roj teeb, coj kev lag luam ua cov khoom lag luam txij nkawm thiab fuse. Fuse. Leading alloys muaj tin thiab antimony yog siv rau kev luam ntawv hom, thiab cov hlau ua hmoov txhuas tau siv rau hauv kev tsim kho cov phiaj txheem. Lead muaj qhov zoo nqus ntawm X-ray thiab gamma rays thiab yog siv dav ua cov ntaub ntawv txij nkawm rau cov khoom siv xoo hluav taws xob. Cov hmoov txhuas tau raug lossis yuav raug hloov los ntawm lwm cov ntaub ntawv hauv qee thaj teb rau cov laj thawj ntawm kev lom zem thiab kev lag luam. Ib qho tseem ceeb tshaj plaws yog siv hauv kev tiv thaiv hluav taws xob. Ntawm no yog li cas cov hmoov txhuas plays lub luag haujlwm hauv kev tiv thaiv hluav taws xob:
A particle particle tsis muaj zog, ib daim ntawv tuaj yeem thaiv; Kev tiv thaiv cov phaj txhuas tuaj yeem thaiv txhua tus, tiv thaiv Alpha Radiat Xyuas Tseem Nco Tsis txhob noj, cov tawv nqaij tsuas. Lwm yog qhov beta ray, uas muaj kev nkag mus. Cov hmoov txhuas thaiv feem ntau tuaj yeem thaiv cov duab txhuas feem ntau yog tiv thaiv nrog ib qho kev thaiv ntawm tus lej qis dua, yog li kom tsis txhob tsim bremsstrahlung. Thaum kawg, Gamma Ray yog tsim nrog α thiab β, nrog rau kev siv lub ntsej muag ua kom muaj zog nrog cov kev tiv thaiv kev tiv thaiv kev tiv thaiv, theoretically tsis tuaj yeem raug thaiv kiag li. Tab sis tsis muaj qhov xav tau rau kev thaiv tag nrho. Qhov tseeb, radiocactivity yog txhua qhov chaw, thiab muaj hluav taws xob hauv qhov chaw ib puag ncig, tsuav nws tau khaws cia nyob rau hauv kev txwv tsim nyog.
