Mhedzisiro yezviyero zveradon zvezvivakwa zveguta zvakapedzwa: kururamisa radon kuri kuitwa mune imwe nzvimbo.

Zvese zvivakwa zveguta reKerava zvakave nezviyero zveradon zvakagadzirwa muchirimo uchishandisa radon yekuyeresa zvirongo, mhedzisiro yacho inoongororwa neRadiation Dziviriro Center (STUK). Zvichienderana nemhedzisiro, pane kudikanwa kwekuita radon kururamisa mune imwe yakavanzika pfuma. Zvichienderana nemhedzisiro, hapana kudikanwa kwemamwe matanho mune zvimwe zvivakwa zveguta. Kuyerwa kwakaitwa munzvimbo makumi manomwe, uko kwaive nehwerengedzo yenzvimbo dzekuyeresa 70, i.e. zvirongo zvekuyeresa.

Mune imwe kuyerwa kwenzvimbo yenzvimbo mukushandiswa kwakavanzika, kukosha kwereferensi yeavhareji yeradon concentration ye300 Bq/m3 yakapfuudzwa. Munguva yezhizha ra2019, iyo saiti ichaitwa radon kugadziridzwa uye iyo yekusimbisa nhanho ichayerwa zvakare zvinoenderana nemirairo yeRadiation Dziviriro Agency mukudonha.

Nezvezvivakwa zveveruzhinji, iyo radon yekumisikidza yaive pazasi kukosha kwereferensi munzvimbo dzese dzekuyerwa, kunze kwekuyerwa kumwe chete. Panguva ino yekuyera, kukosha kwereferensi kwakapfuudzwa, asi Radiation Dziviriro Center haina kuraira mamwe matanho enzvimbo, nekuti haisi nzvimbo yekugara uye saka hapana chikonzero chekudzikamisa radon kuratidzwa.

Nezvigadziriso zveRadiation Act, iyo yakadzokororwa mukupera kwa2018, Kerava ndeimwe yemakanzuru uko kuyerwa kweradon kumabasa kunosungirwa. Mune ramangwana, kuyerwa kweradon kuchaitwa muzvivakwa zvitsva mushure mekutumwa kana mune zvekare zvivakwa mushure mekugadzirisa kukuru, maererano nemirairo yeRadiation Protection Agency, pakati pekutanga kwaGunyana uye kupera kwaMay.
