Thaum Lub Plaub Hlis 18, 2015, Yangzi Yav Hmo Ntuj Xov Xwm tau luam tawm tag nrho nplooj ntawv hu ua "Puas yog tus neeg raug liam tias mob ntsws cancer ntawm tus txiv thiab tus poj niam ib nrab xyoo sib nrug ib qho loj ntawm ntuj marble nyob hauv tsev?" Tshaj tawm ntawm. Nws tau hais hauv tsab xov xwm tias ob tus neeg laus tsis haus luam yeeb, noj zaub mov noj qab haus huv thiab ua haujlwm ntxiv, tab sis lawv tau kuaj pom tias muaj mob qog noj ntshav hauv rau lub hlis. Thaum Song Yong, tus kws kho mob tseem ceeb ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Kab Mob ntawm Nanjing General Tsev Kho Mob ntawm Nanjing Tub Rog Thaj Chaw, tau pab taug qab qhov ua rau, nws pom tias tus txiv neej lub tsev tau dai kom zoo nkauj luxurious thiab siv lub ntuj ntoo loj heev. Tus kws kho mob xav tias qhov teeb meem yog nyob rau hauv no marble [2].
Ua li cas marble ho nrog mob ntsws cancer? Qhov teeb meem yog cov roj hluav taws xob tsis zoo hu ua radon. Radon yog tib yam khoom siv hluav taws xob tsis zoo uas tsim los ntawm kev lwj ntawm radium, thorium thiab lwm yam xov tooj cua hauv cov xwm txheej. Cov pa roj yog xim tsis muaj xim thiab tsis qab. Radon tuaj yeem pom hauv pob zeb, av thiab dej. Tam sim no, radon tau lees paub tias yog qhov thib ob ua rau mob ntsws cancer dua li haus luam yeeb. Raws li Xinmin.com, radon hluav taws xob rau tib neeg lub cev suav txog li 55% ntawm tag nrho cov hluav taws xob tau txais los ntawm tib neeg hauv lawv lub neej. Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb tau teev radon ua ib qho ntawm 19 cov kab mob loj hauv ib puag ncig. Qhov kev pheej hmoo ntawm mob ntsws cancer yog linearly cuam tshuam nrog radon raug. Cov ntaub ntawv pov thawj qhia tau hais tias kwv yees li 50000 tus neeg tuag los ntawm mob ntsws cancer los ntawm radon txhua xyoo hauv Suav teb [2].
Ua li no, nws zoo li tsim nyog tias radon hluav taws xob hauv marble tuaj yeem ua rau mob qog noj ntshav. Yog li, ntau npaum li cas radon marble muaj? Nws puas txaus ua rau mob qog noj ntshav? Puas muaj kev pheej hmoo mob qog noj ntshav thaum siv marble hauv tsev kho kom zoo nkauj [2]?
Cov Xov Xwm Yav Hmo Ntuj Yangtze tom qab xam phaj Zhu Xixu, tus kws kho mob tseem ceeb ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob ntawm Nanjing General Tsev Kho Mob ntawm Nanjing Tub Rog Cheeb Tsam. Cov kws tshaj lij tau hais tias cov neeg nyob hauv yuav tsum tsis txhob txhawj xeeb ntau dhau ntawm kev kho kom zoo nkauj marble hauv lawv lub tsev. Lub xub ntiag ntawm marble tsis tas txhais tau tias ntau dhau radon yuav raug tso tawm. Feem ntau, qhov tshwm sim ntawm sab hauv radon tshaj tus qauv yog tsawg heev. Qhov tseeb tiag, thaum ntxov li 2013, Tuam Tshoj Pob Zeb Association, National Stone Quality Supervision and Inspection Center thiab National Stone Standardization Technical Committee tau koom tes tshaj tawm tsab ntawv ceeb toom hais tias Tsis muaj xov tooj cua txaus ntshai ntawm Marble khoom rau tib neeg, uas piav qhia tias marble feem ntau yog tsim los ntawm carbonate minerals, thiab nws cov txheej txheem tsim tsis ncaj qha rau cov khoom siv hluav taws xob, yog li nws tsis muaj hluav taws xob txaus ntshai rau tib neeg. Raws li rau cov hluav taws xob hluav taws xob ntawm cov khoom siv hluav taws xob hauv marble, Zou Chuansheng, tus thawj tswj hwm ntawm Tuam Tshoj Pob Zeb Association, tau hais hauv kev tshaj tawm ntawm Daim Ntawv Dawb ntawm Suav Ntuj Marbles nyob rau hauv Xiamen hauv xyoo 2014 tias txhua yam hauv qhov xwm txheej yuav muaj xov tooj cua, tab sis peb yuav tsum paub qhov txawv. seb qhov hluav taws xob hluav taws xob no puas tsim kev puas tsuaj rau tib neeg kev noj qab haus huv. Tus neeg txhawb nqa ntawm lub rooj sib tham tau qhia meej tias ntau yam khoom siv pob zeb ua los ntawm ntuj marble yuav tsis ua rau muaj kev phom sij rau tib neeg lub cev. Nyob rau hauv 2013, Nanfang Daily tseem tau tshaj tawm tias National Stone Quality Supervision and Inspection Center tau ua kev soj ntsuam cov xov tooj cua ntawm ntau tshaj 100 yam ntawm cov khoom siv hauv tsev thiab txawv teb chaws marble feem ntau siv hauv kev lag luam hauv 10 xyoo dhau los, thiab cov txiaj ntsig tau qhia tias qhov nruab nrab tshwj xeeb. Kev ua haujlwm ntawm radionuclides ntawm tag nrho cov qauv marble kuaj yog 0.02, uas tsuas yog ib feem tsib ntawm Chav Kawm A Performance index (tsis txwv ntau lawm, kev lag luam thiab siv cov peev txheej) hauv lub teb chaws tus qauv "Radionuclide txwv rau cov khoom siv hauv tsev", Nws tuaj yeem tsis quav ntsej kiag li [2] .
Nws tuaj yeem pom tau tias qhov kev thov tias marble hluav taws xob ua rau mob qog noj ntshav yog qhov tseeb exaggerated. Piv nrog rau cov ntsuas hluav taws xob thoob ntiaj teb, cov ntsuas hauv Suav teb kuj tseem nruj, tab sis nyob rau xyoo tas los no, cov tuam haujlwm cuam tshuam tau tshem tawm cov xov tooj cua pom ntawm marble, uas ua rau pom kev nyab xeeb ntawm cov khoom siv marble hauv tsev. Yog li ntawd, cov neeg siv khoom tuaj yeem yuav cov khoom siv marble nrog kev ntseeg siab hauv cov txheej txheem ntawm kev kho kom zoo nkauj hauv tsev. Txawm li cas los xij, thaum yuav cov khoom siv pob zeb zoo nkauj, cov neeg siv khoom yuav tsum nco ntsoov xyuas "CMA Radioactive Analysis Test Certificate" uas tau lees paub los ntawm Lub Xeev Lub Tuam Txhab Saib Xyuas Kev Tshawb Fawb thiab cov peev txheej ntawm kev siv cov khoom, thiab yuav khoom los ntawm cov tuam txhab tsim khoom.
