Kuopsa kwa Radon Kuchokera ku Granite Countertops
Kodi granite amatha kusokoneza kwenikweni khansa yamapapu? Kodi mungadziwe bwanji? Kodi mungadziwe bwanji ngati muli otetezeka?
Kodi Zizindikiro za Granite Zimatha Bwanji Kansa ya Pakhungu?
Kuda nkhawa za granite kumapangitsa kuti khansa ya m'mapapo ichitike chifukwa timadziwa kuti malo ena enieni akhoza kutulutsa khansa. Kuwonongeka kwabwino kwa uranium komwe kumapezeka mu granite kumapangitsa mpweya wa radon , koma kuchuluka kwa mpweya umenewu kumasiyana kwambiri.
Kuti timvetse bwino izi tiyeni tibwerere ndikukambirana za kufunikira kwa radon mu kansa ya m'mapapo kuti muthe kumvetsa chiopsezo chanu, ngati chiripo.
Radon ndi Exposure ndi Khansa ya M'magazi
Kuwonetsa mpweya wa radon m'nyumba zathu-kotheka paliponse padziko lonse ndi m'ma 50 States-akuganiza kuti ndiyo yachiwiri yomwe imayambitsa khansa ya m'mapapo, ndipo imayambitsa khansa ya m'mapapo mwa osakhala fodya . Popeza khansara yamapapu sichimasuta fodya ndiyo yotsatira 6 yomwe imayambitsa imfa ya khansa ku United States, izi siziri zing'onozing'ono. Poyerekeza mwamsanga, pali amayi pafupifupi 40,000 omwe amafa ndi khansa ya m'mawere ku US chaka chilichonse. Pali anthu 27,000 omwe amafa ndi khansa ya m'mapapo ya rasa . Komabe, timamva zambiri za khansa ya m'mawere.
Kumva mawu radon kukhoza kujambula chithunzi cha abambo anu, koma makamaka, omwe ali pangozi kwambiri ndi omwe amakhala nthawi zambiri panyumba: akazi ndi ana.
Dothi la Radon limachokera ku kuvunda kwabwino kwa uranium, komwe kungakhalepo mu madigiri osiyana mu thanthwe pansi pa nyumba zathu.
Mukawamasulidwa kumtunda kunja, si vuto ngati limasiyana kwambiri. Pamene talowa mumakomo mwathu, magulu angapangitse kukhala apamwamba kwambiri, ndipo pamapeto pake, amabweretsa khansa.
Ma radon ambiri amapezeka chifukwa cha radon yomwe imalowa m'nyumba mwathu kupyolera mu maziko, mapuloteni, ndi zotupa.
Msinkhu wa nyumba yanu siwothandiza, ndipo nyumba zatsopano zingapereke chiopsezo chachikulu chifukwa chokhala losindikizidwa kwambiri.
Bwererani ku Zowonongeka ndi Kuwonetsa Radon
Kafukufuku wasonyeza kuti mayendedwe a granite amatha kutulutsa radon ndi ma radiation, koma nthawi zambiri amakhala otsika kwambiri omwe ali pansi pa mlingo womwe ukupezeka m'nyumba zambiri, komanso pansi pa malire a Environmental Protection Agency (EPA).
Ndikofunika kwambiri, musanayang'ane mwachindunji pa granit, kuti muzindikire kuti zambiri "zachibadwa" zogulitsa zidzanyamula radon pamtundu wina, mwa chikhalidwe chawo. Zida zochokera ku dothi, njerwa zamtengo wapatali, ndi gasi, zitha kukhala ndi radon, ndipo popeza granite ndi yopanda phindu kusiyana ndi zina mwazinthu zina, ziyenera kukhala zovuta kwambiri.
Izi zikuti, kawirikawiri, radon yomwe imachokera kumalo otetezera granite wakhala ofunika kwambiri. Kodi mungatani kuti mukhale otetezeka?
Choyamba - Yesani Kunyumba Yanu
Ngati simunayese nyumba yanu ya radon, sitepe yoyamba iyenera kukhala kuiwala za mapepala anu oyeretsera komanso kuyesa nyumba yanu . Mpata wanu wokhala ndi radon m'nyumba mwanu ndi waukulu kuposa mwayi wanu wotsegula kuchokera pa kompyuta yanu. Zitsulo zimapezeka pa malo osungirako katundu oposa $ 10.
Ngati msinkhu wanu uli wosayenerera (magulu akutchulidwa m'nkhaniyi pamwambapa pa kuyesedwa kwa radon,) onani zowonongekazi pochita kuchepetsa radon .
Gawo Lachiwiri - Taganizirani za Kukhoza kwa Radon mu Mapulani Anu
Ngati mukufuna kupeza lingaliro lanu nokha ngati mapepala anu a granite akudetsa nkhaŵa, mungaganize kuti mukuyesa radon imodzi pamtunda wotsika kwambiri wa nyumba yanu, ndi ina m'chipinda chomwe muli ndi pepala la granite. (Kapena mwina yesero lachitatu mu chipinda chapatali koma pamtunda womwewo monga tsamba lanu la granite.) Ngati mutayesa izi, ndi bwino kuti muike makiti onsewa masentimita 20 pansi, kuchokera pa tsamba la granite.
Ngati magawowa ndi osapitirira, retest onsewa amatha kuwerenga kachiwiri.
Ngakhale makina anu a granite akupereka radon wochuluka, izi sizikutanthauza kuti ayenera kuchotsedwa. Njira zowonetsera mpweya kuti zipititse patsogolo mlengalenga zikhoza kuchepetsa msinkhu wa radon kuti zikhale zoyenera.
Ngati mukudandaula kuti mapepala anu a granite angakhale akukweza mlingo wa radon m'nyumba yanu mutatha kuchepetsa, pali njira zingapo. EPA ikuwonetsa kuti mungagule katswiri wa radon kuti muyesetse kupeza zipangizo zina za radon m'nyumba mwanu monga mapiritsi a granite. Bungwe la American Association of Radon Asayansi ndi Akatswiri a Sayansikali ali ndi mndandanda wa akatswiri odziwa bwino ntchito. Ndikofunika kuzindikira kuti, malinga ndi EPA, ena mwa mayesero omwe akugwiritsidwa ntchito (Geiger counter measurements) si olondola.
Pakalipano, palibe malamulo omwe amafuna kuti opanga azitsulo aziyesa kukhalapo kwa radon mu zomangamanga. Koma izi zingasinthe mtsogolo pamene tikuphunzira zambiri.
Pansi pa Granite Countertops ndi Radon Yopangitsidwa Khansa
Ngakhale kuti pangakhale pangozi yowonongeka kwa rasidi chifukwa cha mapiritsi a granite, chiopsezo choterechi chimawoneka poyerekeza ndi chiwopsezo chomwe chimakhala ndi chiwopsezo cha radon m'nyumba yomwe imakhudzidwa ndi radon mu nthaka pansi pa nyumba kapena ngakhale pansi pamadzi. Kawirikawiri, iwo omwe amafunitsitsa kuchepetsa kuchepa kwa kadojeni akhoza kupeza kuchepa kwakukulu pa zoyesayesa zawo pakuyang'ana njira zina zomwe mungachepetsere chiopsezo cha khansa ya m'mapapo , mwinanso kuwonjezera zina mwaziwisi Matenda a khansa ya m'mapapo ya pansi pamaphunziro anu a tsiku ndi tsiku.
