Iziphumo zemilinganiselo yeradon yezakhiwo zesixeko zigqityiwe: ukulungiswa kweradon kuyenziwa kwindawo enye.

Zonke iipropati zesixeko saseKerava zinemilinganiselo ye-radon eyenziwe entwasahlobo kusetyenziswa izimbiza zokulinganisa i-radon, iziphumo zazo zihlalutywa yiZiko loKhuseleko lweRadiation (STUK). Ngokusekelwe kwiziphumo, kukho imfuneko yokwenza ulungiso lwe-radon kwindawo enye yangasese. Ngokusekelwe kwiziphumo, akukho mfuneko yamanyathelo angaphezulu kwezinye iipropati zesixeko. Imilinganiselo yenziwa kwiindawo ze-70, apho kwakukho iindawo zokulinganisa ze-389, oko kukuthi iingqayi zokulinganisa.

Kwindawo enye yomlinganiselo wepropathi esetyenziselwa bucala, ixabiso lereferensi yomndilili wonyaka woxinzelelo lweradon wama-300 Bq/m3 ligqithiwe. Ngexesha lehlobo le-2019, isayithi liya kulungiswa kwe-radon kwaye inqanaba lokuxininisa liya kulinganiswa kwakhona ngokuhambelana nemiyalelo ye-Arhente yoKhuseleko lweMisebe ekwindla.

Ngokumalunga nezakhiwo zikawonke-wonke, ugxininiso lweradon lwalungaphantsi kwexabiso lereferensi kuzo zonke iindawo zokulinganisa, ngaphandle kwendawo enye yokulinganisa. Kule nqanaba lokulinganisa, ixabiso lereferensi ligqithisiwe, kodwa iZiko loKhuseleko lweRadiation alizange limisele imilinganiselo eyongezelelweyo yesikhala, kuba akusiyo indawo yokuhlala kwaye ngoko akukho mfuneko yokunciphisa i-radon exposure.

Ngezilungiso kuMthetho weRadiation, owahlaziywa ekupheleni kwe-2018, i-Kerava ingomnye woomasipala apho umlinganiselo we-radon kwiindawo zokusebenza unyanzelekile. Kwixesha elizayo, imilinganiselo ye-radon iya kwenziwa kwiipropati ezintsha emva kokugunyaziswa okanye kwiipropati ezindala emva kokulungiswa okukhulu, ngokwemiyalelo ye-Arhente yoKhuseleko lweRadiation, phakathi kokuqala kukaSeptemba nokuphela kukaMeyi.
