Science qhia cov khoom sib xyaw muaj kev nyab xeeb

Tsis muaj xwm txheej

Cleveland, Auj, Cuaj hlis 4, 2008 -Cov ntaub ntawv txheeb xyuas tshaj plaws ntawm cov ntaub ntawv tshawb fawb ntawm RADON tawm ntawm Granite Radon Qib yog hauv qab EPA cov txheej txheem thiab txawm tias qib pom nyob rau hauv huab cua sab nraum zoov.

Txoj kev kawm tshuaj xyuas ntau tshaj li 500 ntsuas ntawm Radon emissions los ntawm Granite luam tawm hauv cov phooj ywg phau ntawv sau cia. Nws qhia tau tias qhov nruab nrab granite slab pab txhawb rau sab hauv radon qib uas yog:

300 lub sij hawm qis dua qib radon nyob rau sab nraum zoov huab cua,
1,000 zaus hauv qab qhov nruab nrab nruab nrab ntawm Radon pom nyob rau hauv huab cua ntawm peb tsev, thiab
3,000 zaus tsawg dua li theem kev nqis tes rau sab hauv huab cua pom zoo los ntawm Asmeskas ib puag ncig kev tiv thaiv lub koomhaum (EPA).

"Peb tau saib cov ntaub ntawv tshaj tawm los ntawm txhua tus phooj ywg - Tus thawj coj ntawm kev noj qab haus huv," Tsis muaj lub ntsiab lus pom tseeb "Kom pom tseeb, tus lej tuaj ntawm cov kev tshawb fawb tshawb fawb txog lwm cov kws tshawb fawb, uas tau ntsib ntau dua cov ntaub ntawv feem ntau tau tshaj tawm hauv cov xov xwm nrov."

"Hauv kev xav txog kev noj qab haus huv rau pej xeem, peb nug cov lus nug tseem ceeb {{}} Ntau npaum li cas cov pob zeb countertops pab txhawb rau tus nqi radon hauv Asmeskas tsev?" Mccarthy nug. "Cov lus teb yog tsawg heev, raws li cov pov thawj zoo tshaj plaws uas muaj nyob rau lub sijhawm no."

Kev tsom xam tau ntsuas tshaj tawm radon thiab ntsuas qhov cuam tshuam lawv yuav muaj nyob rau theem radon tam sim no nyob hauv lub tsev raug. Qhov kev tshawb pom pom tias nruab nrab pob zeb yuav pab txhawb nqa NW nyuam qhuav radon. Txawm tias qhov siab tshaj plaws emitting lub pob zeb nyob rau hauv lub tsev nruj tshaj plaws tseem yuav ua rau cov qib radon 70 npaug qis dua EPA kev txiav txim siab.

"Txoj kev tshawb no zoo ib yam nkaus nrog txhua qhov kev tshawb fawb peb tau pom yav dhau los, lub teb chaws muaj kev phom sij hauv Marble, uas tau muaj txiaj ntsig ntawm cov tshuaj ntsuam kev noj qab haus huv ntawm cov countertops. "Txawm hais tias qhia txog kev txhawj xeeb txog kev nyab xeeb txog kev nyab xeeb ntawm granite countertops, kev tshawb fawb txuas ntxiv cov ntawv ceeb toom tsis muaj qhov tseeb."

Tom qab cov lus qhia tsis ntev los no cov countertops tuaj yeem txaus ntshai, kev tshawb fawb loj hlob tau rov qab ua kom muaj kev pheej hmoo txaus ntshai. Kev tshawb fawb thiab cov koom haum pej xeem uas tau sib txuas rau kev nyab xeeb ntawm cov countertopttops xws li:

Washington State Department of Washingment of Health, uas tau hais tias Radon qhov teeb meem yuav tsum tsis yog "txiav txim siab txog kev ua txhaum lossis tsis txhob tau txais granite countertops."

American Assient cov kws tshawb fawb thiab thev naus laus zis (AART), uas cov neeg uas cov kws tshaj lij hauv daim teb Radon kev sim thiab tshawb fawb.
Kev Noj Qab Haus Huv Lub Koom Haum (HPS), yog lub koom haum kws tshawb fawb thiab cov neeg ua haujlwm tshwj xeeb hauv kev nyab xeeb hauv kev ua haujlwm thiab kev nyab xeeb ib puag ncig.
Dr. Ll Chyi, xibfwb ntawm Geochemistry thiab ib puag ncig genology ntawm Chav Lis Haujlwm Genology thiab ib puag ncig kev tshawb fawb, University of Akron.
Florida Lub Chaw Haujlwm Saib Xyuas Kev Noj Qab Haus Huv, uas nws tus kheej txoj kev xeem granite qhia lub pob zeb ua kev pheej hmoo.
Lub Tsev Haujlwm Texas cov chaw pabcuam kev noj qab haus huv, uas tau hais meej meej txog cov qib hluav taws xob ntau dua los ntawm cov countrying tshaj los ntawm granite countertops.
Lub North Carolina geological kev tshawb fawb, uas lawb tawm granite - Raws li kev pheej hmoo txaus ntshai.
Teb Chaws Asmeskas Kev Pabcuam Tiv Thaiv Ib Puag Ncig, uas nyuam qhuav hloov kho cov countertops: "Raws li cov kev tshawb fawb hauv tsev tsis paub txog kev txhawb nqa hluav taws xob thiab cov radon hauv nruab nrab tsev."

Ib daim qauv ntawm kev kawm tiav, suav nrog cov ntawv sau cia ntawm cov ntawv cim uas nws tau txheeb xyuas, tuaj yeem rub tawm los ntawm Marble Lub koom haum ntawm Asmeskas ntawm

Hais txog Lub Koom Haum Marble ntawm America

Rau ntau tshaj 60 xyoo Lub Tsev Haujlwm Marble ntawm America (Mia) tau yog lub ntiaj teb cov ntaub ntawv pabcuam kev pab cuam thiab tus neeg tawm tsam cov ntaub ntawv thiab kev lag luam nruab nrab ntev. Mia cov tswv cuab suav nrog Marble, Granite, Sandstone, thiab lwm yam pob zeb tsim khoom, chaw faib khoom, thiab cog lus thoob ntiaj teb.
