Izilinganiso ze-radon ziqala ezindaweni ezintsha nezilungisiwe zedolobha
Idolobhakazi lizoqhubeka nezilinganiso ze-radon ezaqalwa ngo-2019 ngokuhambisana nomthetho omusha wemisebe ezindaweni ezintsha nezilungisiwe eziphethwe yidolobha ezasetshenziswa ngonyaka odlule futhi ezinezindawo zokusebenza ezihlala unomphela.
Idolobhakazi lizoqhubeka nezilinganiso ze-radon ezaqalwa ngo-2019 ngokuhambisana nomthetho omusha wemisebe ezindaweni ezintsha nezilungisiwe zedolobha ezasetshenziswa ngonyaka odlule futhi ezinezindawo zokusebenza ezihlala njalo. Ukulinganisa ngokulandela imiyalelo ye-Swedish Radiation Protection Agency kuzoqala ngoJanuwari-February futhi zonke izilinganiso zizoqedwa ekupheleni kukaMeyi. Ukusebenza emagcekeni lapho ukukalwa kwe-radon kwenziwa khona kuyaqhubeka njengokujwayelekile.
Izilinganiso ze-radon zenziwa ngosizo lwezimbiza zokulinganisa ezimnyama ezifana nama-hockey pucks, abekwe endaweni ukuze ikalwe ngenani elidingekayo ngokusho kobukhulu bayo. Izilinganiso endaweni eyodwa zihlala okungenani izinyanga ezimbili, kodwa ukuqala kwesikhathi sokulinganisa kuyahluka phakathi kwezakhiwo ezihlukene. Ekupheleni kwesikhathi sokulinganisa, zonke izimbiza zokulinganisa endaweni zilethwa esikhungweni sokuvikela imisebe ukuze zihlaziywe. Imiphumela yocwaningo lwe-radon izomenyezelwa entwasahlobo ngemva kokuphothulwa kwemiphumela.
Ngezichibiyelo zomthetho wemisebe ovuselelwe ekupheleni kuka-2018, iKerava ingomunye womasipala lapho izilinganiso ze-radon ezindaweni zokusebenza ziyimpoqo. Ngenxa yalokhu, idolobha lakala ukugxiliswa kwe-radon kuzo zonke izakhiwo eziphethe ngo-2019. Ngokuzayo, izilinganiso ze-radon zizokwenziwa ezindaweni ezintsha ngemva kokugunyazwa nasezindaweni ezindala ngemva kokulungiswa okukhulu, ngokuya ngemiyalelo ye-Radiation Protection Agency. , phakathi kokuqala kuka-September nokuphela kuka-May.
