Tom qab formaldehyde tau dhau los ua kev ntshai ntawm kev txhim kho hauv tsev hauv tib neeg lub siab, kev noj qab haus huv ntawm marble kuj tau dhau los ua qhov kev txhawj xeeb thib ob hauv tib neeg lub siab. Keeb kwm, txhua leej txhua tus xav tias pob zeb yog cov khoom kho kom zoo nkauj tshaj plaws, txawm tias nws yog pob zeb ntuj lossis pob zeb dag. Kev xaiv, tab sis tsis tu ncua ntawm cov ntaub ntawv tsis zoo kuj tau mus txog tib neeg lub pob ntseg, thiab leej twg yog thiab leej twg tsis yog yuav tsum tau ua tib zoo tshawb xyuas.
Hais txog kev phom sij ntawm marble, koj tuaj yeem nrhiav ntau cov lus ceeb toom txog cov roj radon uas tsim los ntawm marble yog tias koj tshawb hauv Is Taws Nem casually. Radon yog ib qho tsis muaj xim, tsis muaj ntxhiab thiab tsis pom zoo cov pa roj. Radon thiab nws cov progeny generated los ntawm marble hluav taws xob nkag mus rau tib neeg lub cev nrog cov huab cua, los yog txuas mus rau lub tracheal mucosa thiab lub ntsws nto, los yog yaj mus rau hauv lub cev kua thiab nkag mus rau hauv hlwb thiab cov ntaub so ntswg, tsim hluav taws xob nyob rau hauv lub cev. , induce ntsws cancer, leukemia thiab kab mob ua pa.
Raws li Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Hauv Ntiaj Teb, radon yog qhov thib ob uas muaj carcinogen tom qab haus luam yeeb. Yog li ntawd, ntau tus neeg txhawj xeeb tias marble hluav taws xob yuav ua rau peb noj qab haus huv.
Hais txog hluav taws xob phom sij ntawm marble dav rumored nyob rau hauv Internet, tam sim no muaj lwm lub suab, "Qhov tseeb, tsuav yog muaj radon nyob rau hauv lub tsev, tshwj xeeb tshaj yog tus nqi ntawm radon generated nyob rau hauv lub qub tsev yog siab dua nyob rau hauv lub tsev tshiab." "Lub tsev. Tsis marble tsuas yog tsim radon. Yog li peb tsis tas yuav txhawj xeeb txog qhov hu ua marble phom sij. Artificial marble tsis muaj teeb meem ntau dua li ntuj marble."
Cov qauv tsim ntawm marble yog tag nrho nyob rau hauv qhov kev nyab xeeb ntawm Lub Xeev Lub Chaw Tiv Thaiv Ib puag ncig, thiab txhua tus tuaj yeem siv nrog kev ntseeg siab. Cov hluav taws xob ntawm marble feem ntau qis dua 13μGy / h. Hauv cov ntaub ntawv saib xyuas ib puag ncig, koj yuav pom tias cov hluav taws xob yog 20 μGy / h (micro Gy / h). Kev phom sij tsis suav nrog hauv qab no.
Raws li rau "Marble vuas muaj hluav taws xob", cov tub lag luam muaj kev xav sib txawv. Txhawm rau rov qab qhov tseeb ntawm qhov xwm txheej, Zhu Li, tus thawj coj ua haujlwm ntawm Lub Chaw Tiv Thaiv Hluav Taws Xob ntawm Tsinghua University hauv Suav teb, tus kws kho mob ntawm geochemistry, tau ua qhov kev tshuaj xyuas ntawm qhov chaw ntawm cov nqi hluav taws xob ntawm marble hluav taws xob nrog cov cuab yeej tshaj lij. Cov txiaj ntsig kev sim tau pom tias tag nrho peb cov khoom siv coj mus kuaj ua rau muaj kev hloov pauv ntawm cov hluav taws xob sab hauv tsev. Cov vuas dub marble nce qhov ntsuas hluav taws xob los ntawm 2105cpm rau 2416cpm. Cov qauv pobzeb daj thiab dawb kuj nce qhov ntsuas emissivity. Puas muaj hluav taws xob puas tsuaj rau marble?
Xibfwb Zhu Li cov ntsiab lus ntawm qhov chaw: Cov qauv xeem yog cov khoom siv hauv tsev A-qib thiab muaj kev nyab xeeb siv! Raws li cov lus ceeb toom: Tam sim no, Tuam Tshoj tus qauv tsim cov khoom siv nruj me ntsis tswj cov qauv ntawm cov xov tooj cua.
Muaj peb qib A, B, thiab C. Piv txwv li, cov khoom siv hauv tsev nrog cov nqi emission nyob rau hauv chav kawm A tsis txwv rau lawv qhov kev siv thiab tsim nyog siv rau txhua qhov chaw. Chav B cov ntaub ntawv hauv tsev raug txwv rau thaj chaw uas tsis yog chav pw. Cov ntaub ntawv hauv tsev Class C tsuas yog tsim rau sab nraum zoov lossis lwm yam siv. Yog li ntawd, qhov ntxoov ntxoo ntawm cov xim puas yuav cuam tshuam rau cov hluav taws xob ntawm marble? Xibhwb Zhu tau hais tias cov xim ntawm lub pob zeb tuaj yeem siv los ua cov ntaub ntawv, yog li tsis muaj kev siv rau cov vuas!
