Kuleli sonto, i-IAEA ihlele umhlangano we-inthanethi ukuze kubhekwe inqubekela phambili ekunciphiseni izingozi ezihlobene nemisebe yeziguli ezidinga izithombe zezokwelapha njalo, ngenkathi kuqinisekiswa ukulondolozwa kwezinzuzo. Emhlanganweni, ababekhona baxoxe ngamasu okuqinisa iziqondiso zokuvikelwa kweziguli nokusebenzisa izixazululo zobuchwepheshe zokuqapha umlando wokuchayeka kweziguli. Ngaphezu kwalokho, babuyekeze izinhlelo zomhlaba wonke ezihlose ukuthuthukisa njalo ukuvikelwa kwemisebe yeziguli.
"Nsuku zonke, izigidi zeziguli ziyazuza ekuhlolweni kwezithombe okufana ne-computed tomography (CT), ama-X-ray, (okugcwaliswa ngemidiya ephikisanayo futhi ngokuvamile izinhlobo ezine ze-"ama-injector acwebezelayo acindezelwe kakhulu: Umjovo owodwa we-CT, Umjovo wekhanda eliphindwe kabili we-CT, Umjovo we-MRI, futhiI-Angiography or I-DSA high pressure contrast media injector(futhi kubizwa ngokuthi “ilabhorethri ye-cath“),kanye nesirinji namapayipi athile), kanye nezinqubo zokungenelela eziqondiswa yizithombe, izinqubo zokwelapha ngenyukliya, kodwa ngokusetshenziswa okwandisiwe kwezithombe zemisebe kuvela ukukhathazeka ngokwanda kokuvezwa kwemisebe ezigulini,” kusho uPeter Johnston, uMqondisi we-IAEA Radiation, Transport and Waste Safety Division. “Kubalulekile ukusungula izinyathelo eziqondile zokuthuthukisa izizathu zokuthathwa kwezithombe ezinjalo kanye nokwenza ngcono ukuvikelwa kwemisebe kwesiguli ngasinye esithola ukuxilongwa nokwelashwa okunjalo.”
Emhlabeni jikelele, kwenziwa izinqubo zokuxilonga ngemisebe kanye nemithi yenuzi ezingaphezu kwezigidigidi ezine minyaka yonke. Izinzuzo zalezi zinqubo zidlula kakhulu noma yiziphi izingozi zemisebe uma zenziwa ngokuhambisana nezizathu zezokwelapha, kusetshenziswa ukuvezwa okuncane okudingekayo ukuze kufezwe imigomo yokuxilonga noma yokwelapha edingekayo.
Umthamo wemisebe ovela enkambisweni yokuthwebula izithombe yomuntu ngamunye uvame ukuba mncane kakhulu, ngokuvamile uhluka kusukela ku-0.001 mSv kuya ku-20-25 mSv, kuye ngohlobo lwenqubo. Leli zinga lokuchayeka lifana nemisebe yangemuva abantu abahlangana nayo ngokwemvelo esikhathini esiyizinsuku eziningana kuya eminyakeni embalwa. UJenia Vassileva, uchwepheshe Wokuvikela Imisebe e-IAEA, uxwayise ngokuthi izingozi ezingaba khona ezihlobene nemisebe zingase zande lapho isiguli sidlula ochungechungeni lwezinqubo zokuthwebula izithombe ezihilela ukuchayeka kwemisebe, ikakhulukazi uma zenzeka ngokulandelana.
Ochwepheshe abangaphezu kuka-90 abavela emazweni angu-40, izinhlangano zomhlaba wonke ezingu-11 kanye nezinhlangano zobungcweti babe khona emhlanganweni kusukela mhla ziyi-19 kuya ku-23 Okthoba. Abahlanganyeli babehlanganisa ochwepheshe bokuvikela imisebe, odokotela bemisebe, odokotela bemithi yenuzi, odokotela, ososayensi bezokwelapha, ochwepheshe bemisebe, ososayensi bezinto ezibangela imisebe, ososayensi bezinto ezibangela imisebe, ososayensi bezifo ezibangelwa amagciwane, abacwaningi, abakhiqizi kanye nabamele iziguli.
Ukulandelela ukuchayeka kwemisebe kweziguli
Imibhalo enembile nehambisanayo, ukubika, kanye nokuhlaziywa kwemithamo yemisebe etholwa yiziguli ezikhungweni zezokwelapha kungathuthukisa ukuphathwa kwemithamo ngaphandle kokubeka engcupheni ulwazi lokuxilonga. Ukusebenzisa idatha eqoshiwe evela ezivivinyweni zangaphambilini kanye nemithamo enikezwayo kungadlala indima ebalulekile ekugwemeni ukuchayeka okungadingekile.
UMadan M. Rehani, uMqondisi we-Global Outreach for Radiation Protection eMassachusetts General Hospital e-United States kanye noSihlalo womhlangano, wembule ukuthi ukusetshenziswa okwandisiwe kwezinhlelo zokuqapha ukuchayeka kwemisebe kunikeze idatha ephakamisa ukuthi inani leziguli eziqoqa umthamo osebenzayo we-100 mSv nangaphezulu eminyakeni eminingana ngenxa yezinqubo ze-computed tomography eziphindaphindwayo liphakeme kunalokho obekulindelwe ngaphambilini. Isilinganiso somhlaba wonke simi ezigulini eziyisigidi ngonyaka. Ngaphezu kwalokho, wagcizelela ukuthi isiguli esisodwa kwezihlanu kulesi sigaba kulindeleke ukuthi sibe ngaphansi kweminyaka engama-50 ubudala, ephakamisa ukukhathazeka ngemiphumela engaba khona yemisebe, ikakhulukazi kulabo abaphila isikhathi eside kanye namathuba aphezulu omdlavuza ngenxa yokuchayeka kwemisebe okwandisiwe.
Indlela Eya Phambili
Abahlanganyeli bafinyelele esivumelwaneni sokuthi kunesidingo sokusekelwa okuthuthukisiwe nokuphumelelayo kweziguli ezibhekene nezifo ezingamahlalakhona nezimo ezidinga ukuthwetshulwa kwezithombe njalo. Bavumelana ngokubaluleka kokusebenzisa kabanzi ukulandelela ukuchayeka emisebeni nokuyihlanganisa nezinye izinhlelo zolwazi lwezempilo ukuze kufezwe imiphumela emihle kakhulu. Ngaphezu kwalokho, bagcizelele isidingo sokuthuthukisa ukuthuthukiswa kwamadivayisi okuthwetshulwa kwezithombe asebenzisa imithamo encishisiwe kanye namathuluzi esofthiwe okuqapha imithamo ejwayelekile ukuze kusetshenziswe emhlabeni jikelele.
Kodwa-ke, ukusebenza kahle kwamathuluzi anjalo athuthukile akuxhomekile kuphela emishinini nasezinhlelweni ezithuthukisiwe, kodwa nasebucikweni babasebenzisi njengodokotela, izazi zefiziksi zezokwelapha, kanye nochwepheshe. Ngakho-ke, kubalulekile ukuthi bathole ukuqeqeshwa okufanele kanye nolwazi lwakamuva mayelana nezingozi zokukhishwa kwemisebe, ukushintshana ngolwazi, kanye nokuxhumana okusobala neziguli kanye nabanakekeli mayelana nezinzuzo kanye nezingozi ezingaba khona.
