Ukuchayeka kwigesi ye-radon kuyimbangela yesibili ehamba phambili yomdlavuza, ngokusho kwe-a ucwaningo olusha lwezwe lonke eholwa umcwaningi waseNyuvesi yaseCalgary.
Ababhali bathi lolu cwaningo, olukhishwe ngoLwesithathu, luyisibuyekezo sokuqala esibanzi mayelana nokuchayeka kwe-radon eCanada kusukela ngo-2012.
Ithi cishe amaphesenti angu-17.8, noma amakhaya aseCanada ayizigidi ezingu-10.3, aqukethe amazinga ayingozi egesi ebangela umdlavuza. Lokho kungaphezu kokuphindwe kabili kwamaphesenti angu-7 emizi okwakulinganiselwa ukuthi inamazinga e-radon ocwaningweni olukhulu lokugcina ngo-2012.
Ucwaningo olusha olunzulu luthi cishe amaphesenti angu-17.8, noma amakhaya aseCanada ayizigidi ezingu-10.3 aqukethe amazinga ayingozi egesi ye-radon ebangela umdlavuza.

I-Radon iyigesi engenambala, engenaphunga, enemisebe eyakha ngokwemvelo lapho i-uranium, i-thorium noma i-radium – izinsimbi ezikhipha imisebe – ziphuka emadwaleni, enhlabathini nasemanzini angaphansi komhlaba.
Ukuchayeka kuvela ekuphefumuleni i-radon emoyeni engena ezakhiweni nasekhaya ngokusebenzisa imifantu nezikhala futhi kwandisa ingozi yamangqamuzana amaphaphu aguquke abe umdlavuza, ikakhulukazi uma evezwa eminyakeni eminingi noma enanini elikhulu kakhulu le-radon.
Umhlahlandlela we-Health Canada we-radon izinga lika-200 Bq/m3 futhi uma lingaphezu kwalokho, i I-Canadian Cancer Society uthi umnikazi womuzi kufanele sebenzisana nochwepheshe ukuze behliswe.
Lolu cwaningo “lunikeza ukuqonda okwengeziwe kokuthi abantu abahlala eCanada ngawo-2020 bachayeka kanjani ku-radon emiphakathini yethu ehlukahlukene, ezindlini nasezifundeni,” kusho uDkt. Aaron Goodarzi, uprofesa we-biochemistry kanye ne-molecular biology e-University of Calgary’s. Isikole Sezokwelapha saseCumming.
Ukuchayeka kurediyo kuvela ekuphefumuleni komoya ongena ezakhiweni nasekhaya ngemifantu nezikhala.
Izindaba Zomhlaba
Ucwaningo lwango-2024 luhlanganisa ukufundwa okungu-75,000 okuvela ezakhiweni zokuhlala zasemadolobheni nezasemaphandleni kulo lonke elaseCanada.
Lo mbiko uqukethe futhi izibalo eziphindwe kahlanu kunezi-14,000 ezathathwa ngo-2012.
Thola izindaba zezempilo zamasonto onke
Thola izindaba zakamuva zezokwelapha nolwazi lwezempilo olulethwa kuwe njalo ngeSonto.
“Ngokombono wami njengomcwaningi ofunda lokhu eminyakeni eyi-10 edlule, akumangazi. Njengommeli wokuvikela umdlavuza wamaphaphu, kuyathusa impela,” kusho uGoodarzi.

Imiphakathi yasemaphandleni ibhekene nezingozi ezinkulu zokuchayeka kwe-radon: abacwaningi
ECalgary nase-Edmonton, umbiko uthi cishe indawo eyodwa kweziyisithupha inamazinga e-radon noma ngaphezulu kwemihlahlandlela ye-Health Canada.
Emiphakathini yase-High River, Okotoks nase-Strathmore, okungenani ikota eyodwa ukuya kuhhafu wezindawo zokuhlala ziqukethe i-radon eku-200 Bq/m³ noma ngaphezulu.
Eminye yemiphumela eyinhloko yocwaningo ihlanganisa:
- Ibhilidi eli-1 kwezingu-5 zokuhlala zaseCanada liku-200 Bq/m³ noma ngaphezulu;
- Indawo engu-1 kwezi-4 zasemakhaya ePrairie kanye ne-NWT iku-200 Bq/m³ noma ngaphezulu;
- Indawo engu-1 kwezingu-6 zasemadolobheni ePrairie kanye ne-NWT iku-200 Bq/m³ noma ngaphezulu;
- Izakhiwo ezi-1 kwezingu-5 ze-Prairie kanye ne-NWT ezihlukanisiwe ziku-200 Bq/m³ noma ngaphezulu;
- Indawo engu-1 kwezingu-6 ePrairie kanye ne-NWT Ehlukaniswe kancane iku-200 Bq/m³ noma ngaphezulu;
- Indawo engu-1 kwezingu-10 iPrairie kanye nesitayela seRow ye-NWT iku-200 Bq/m³ noma ngaphezulu.
UGoodarzi uthe kungenzeka ukuthi ukunyuka kwe-radon kube ngokwengxenye ngoba ukufunda kuthathwe phansi noma endaweni engaphansi uma kuqhathaniswa nendlu yonke.
Uthe ukwakhiwa kwezindlu ezintsha nakho konga amandla futhi kucupha i-radon ngaphakathi.
“Abantu baseCanada baphakathi kwabantu abachayeka kakhulu yi-radon eMhlabeni, futhi lokho kusho ukuthi sidinga ukubhekana nalokhu ukugwema ikusasa lomdlavuza wamaphaphu odlangile kodwa ogwemeka ngenye indlela,” kwengeza uGoodarzi.
Abantu badinga ukufaka imitshina ye-radon ezindlini zabo futhi bathathe izinyathelo zokususa amazinga aphezulu egesi, kwengeza u-Goodarzi.
Unethemba lokuthi kuzophinde kwenziwe izinguquko ekwakhiweni kwezindlu ezintsha ezizobhekelela i-radon.
I-Canadian Cancer Society ithi abanikazi bezindlu abanamazinga aphezulu e-radon kufanele basebenzisane nochwepheshe ukuze behlise.
Izindaba Zomhlaba
Lo mbiko uxhaswe yiCanadian Institutes of Health Research Healthy Cities Research Initiative, i-Health Canada, i-Alberta Real Estate Foundation kanye neCanadian Cancer Society.
Umfelandawonye wabacwaningi uhlanganisa ososayensi abavela e-Health Canada nase-CAREX Canada.
“Ngikhathazeke kakhulu. Ngicabanga ukuthi ukunemba kwedatha yombiko omusha kunamandla kakhulu, ”kusho u-Allison Wallace, udokotela ohlinza isifuba e-QEII Health Sciences Center eHalifax kanye nombhali ngokubambisana walo mbiko.
“Izinombolo zangempela futhi abantu kufanele bazithathele phezulu.”
ILung Health Foundation income lo mbiko “ngomyalezo wawo ocacile nophuthumayo.”
“Manje siyazi ukuthi cishe amaphesenti angu-18 emizi yaseCanada aqukethe amazinga e-radon ayingozi adinga isinyathelo esisheshayo. Kubi kakhulu kunalokho ebesikucabanga ngaphambilini,” kusho uJessica Buckley, umongameli kanye ne-CEO yenhlangano
“Sicabanga ukuthi kuzogqugquzela abantu baseCanada abaningi ukuthi bahlole amakhaya abo nezindawo zokusebenza.”
