I-lymphocytic leukemia , noma i-CLL, i-leukemia evame kakhulu emhlabeni wesentshonalanga. Ilandisa ngamaphesenti angaba ngu-30 azo zonke i-leukemi.
I-CLL futhi i- leukemia evame kakhulu kubantu abadala e-United States. Njengama-cancer amaningi, imbangela yayo eqondile ayifakazi, futhi futhi njengamanye amagciwane kaningi, akwamanje okwamanje amasu atholakala ekuvimbeleni.
Ngaphandle komthetho?
I-radiation yinto eyaziwayo engozini yezinhlobo ezithile ze-leukemia, kodwa i-CLL ibhekwe njengento ehlukile kulowo mthetho.
Le mbono isekelwe ekubonweni okuningi . Isibonelo, abantu abavezwe ngama-radiation aphakeme kakhulu - njengezikhathi zengozi ezitshalweni zamandla enyukliya - bavame ukuthuthukisa ezinye izinhlobo ze-leukemia - kodwa hhayi CLL . Futhi ngakho ukuxhumana phakathi kwemisakazo kanye ne-CLL kuye kwaba impikiswano. Kodwa-ke, isifundo esisha sibheka ukuthi kungenzeka ukuthi i-radon - umthombo wemisebe - ingachaza amaphethini athile aboniswe nge-CLL.
I-Radon: I-Natural, i-Radiation Ehamba Ngomoya
I-Radon iyi-gesi evuthayo. Ayibonakali futhi ayikho iphunga noma inambitha. Kunezinhlobo ezahlukene zemisebe, futhi imisebe evela ku-radon, eyaziwa ngokuthi i-ray ray, ayikwazi ukungena esikhunjeni noma izingubo zokugqoka, futhi ihamba kuphela ngamasentimitha ambalwa ukusuka emthonjeni wayo emoyeni. Uma umthombo ukhala noma usungisiwe, lokho kungaba yinkinga yempilo yabantu. Uma uphefumulela umoya oqukethe i-radon, umzimba wakho ubonakala, futhi lokhu kuyimbangela eyodwa yomdlavuza wamaphaphu.
I-EPA ilinganisela ukuthi i-radon ibangela izinkulungwane zabantu abafa njalo ngonyaka - ezinye zazo kubantu abangakaze bapheze. Eqinisweni, udokotela ohlinzayo uxwayise ukuthi i-radon iyimbangela yesibili yomdlavuza wamaphaphu e-United States namuhla. Ukubhema kuphela kubangela ukufa kwabantu abaningi emdlalweni wamaphaphu. Uma wenza okwenzekayo ukubhema , futhi ikhaya lakho linamazinga aphezulu e-radon, ingozi yakho yomdlavuza wamaphaphu iphezulu kakhulu, ngokusho kwe-EPA.
Uvelaphi Radon?
Njengezinyosi zelanga nezinyoka eziyingozi, i-radon ivela emvelweni: ukuwohloka kwemvelo kwe-uranium emhlabathini, edwaleni namanzi futhi kufinyelele emoyeni ophefumulayo. I-Radon ingatholakala kuwo wonke ama-United States. I-Radon ingangena kunoma yiluphi uhlobo lwesakhiwo njengamakhaya, izikole namahhovisi, futhi kungaholela ekwenzeni izinga eliphezulu eliphezulu le-radon. I-EPA inikeza ulwazi mayelana "nezindawo ze-radon" kufaka phakathi ibalazwe elihlangene. Amanothi e-agency, kodwa-ke, ukuthi imephu ayihloselwe ukusetshenziselwa ukucacisa ukuthi ngabe ikhaya elisezindaweni elinikeziwe kufanele lihlolwe yini i-radon, ngoba amakhaya angenawo amazinga aphezulu e-radon atholakala kuzo zonke izindawo ze-EPA.
I-Radon ne-CLL
Kuze kube manje, ubudlelwane obuphakathi kuka-radon no-CLL yiyona mbono ehlanzekile - inhlangano esekelwe kulolu cwaningo olulodwa, futhi mhlawumbe izifundo ezimbalwa ezincane okungenzeka ziye zafakazela ekutholeni okufanayo. Akukho okwanele ubufakazi obucacile bokusekela lo mbono; Kodwa-ke, yilokho okucatshangelwayo okwamanje.
Isifundo se-2016
"Kuyaziwa ukuthi izifundo ze-ecologic, kufaka phakathi lezo ezibandakanya i-radon, zingahle zidukise," kusho abalobi balezi zifundo zakamuva, njengoba bevuma ukuthi kunendawo ephelele yephutha lapha.
Noma kunjalo, abacwaningi ababili abashicilela ngoJanuwari 2016 "I-Future Oncology," baphawula ukuthi indawo ye-CLL ayiyona engahleliwe, kanti amanani aphakeme ayenzeka emazweni asezindaweni zasemaphandleni enyakatho nephakathi kwe-USA.
Bakuthola lokhu kanzima ukuchaza. Futhi bayaqaphela ukuthi, kubantu abaningi, i-radon iyona mthombo omkhulu wokuvezwa kwemisebe ye-ionizing.
Laba baphandi babheka izinga lemigomo elilinganiselwa kudala le-CLL e-US futhi bazama ukulinganisa ukuvezwa kwabantu kulawa kuthiwa yi-radon usebenzisa isistimu yokulinganisa - nezibalo ukuzama ukulungisa izinto ezithile ezaziwayo ezingahle zidaka amanzi.
Ukusebenzisa lo modeli wokubala, babone ubudlelwane phakathi kwe-CLL ne-radon, beqaphela ukuthi le nhlangano izobuyiselwa futhi iqinisekiswe - ngoba abantu, hhayi bathi, bahlakulele i-CLL.
Ngaphansi
Lolu cwaningo lunokuthola okuthakazelisayo futhi luhlinzekela uphenyo olwengeziwe. Lokhu kwakungokutholwa kokuqala ngomqondo wokuthi abacwaningi babekhathazeke ngokuyinhloko ngombuzo othi, " Kungenzeka yini ukuthi amazinga ka-radon angabandakanyeka ekuthuthukiseni i-CLL?" Abalobi basikisela ukuthi okutholakele kulolu cwaningo kuhlinzeka ngemigomo kulabo abangase baphathe ngokuhamba kwesikhathi nombuzo wokuthi noma ngabe abantu ngabanye abavezwe kumazinga aphezulu e-radon basengozini enkulu yokuthuthukisa i-CLL.
