Marble rooj tog muaj cov kev xav tau siab ntawm lub suab thiab kev tiv thaiv ib puag ncig ntawm lub rooj tsavxwm, thiab kev tswj hwm nruj ntawm cov xov tooj cua ntawm lub pob zeb. Tau ntev, tib neeg xav yuam kev tias cov rooj tog marble yuav muaj hluav taws xob, yog li lawv inevitably muaj qee qhov kev txhawj xeeb thaum yuav khoom. Qhov tseeb, radioactivity ntawm marble yog tsawg heev thiab yuav tsis ua mob rau tib neeg lub cev.
Nws yog qhov tseeb tias marble muaj hluav taws xob. Nws yuav tsum tau hais tias txhua lub pob zeb muaj hluav taws xob. Nws nyob ntawm qhov loj ntawm cov hluav taws xob. Rau cov xov tooj cua ntawm marble, cov kws tshaj lij los ntawm Standardization Institute ntawm National Building Materials Administration ntseeg tias cov hluav taws xob hluav taws xob muaj nyob hauv qhov xwm txheej. Ib yam li ntawd, muaj cov xov tooj cua hauv cov khoom siv pob zeb ntuj. Tus yuam sij yog saib seb nws puas dhau lub teb chaws tus qauv. Marble yog tsim los ntawm limestone nyob rau hauv sedimentary pob zeb los ntawm metamorphism nyob rau hauv kev cuam tshuam ntawm lwm yam xws li kub thiab siab. Cov xov tooj cua ntawm calcite thiab dolomite feem ntau qis heev, yog li cov xov tooj cua ntawm marble metamorphosed los ntawm cov xov tooj cua tsis tshua muaj limestone kuj tsawg heev.
Qhov txwv radionuclide ntawm granite thiab marble slab yuav tsum ua raws li cov kev cai ntawm GB 6566-2001 Txwv ntawm Radionuclide hauv Cov Khoom Siv Hauv Tsev
