Kuleli sonto, i-IAEA ihlele umhlangano obonakalayo ukuze kubhekwane nenqubekelaphambili ekunciphiseni ubungozi obuhlobene nemisebe ezigulini ezidinga izithombe zezokwelapha ezivamile, kuyilapho iqinisekisa ukulondolozwa kwezinzuzo. Emhlanganweni, ababekhona baxoxisane ngamasu okuqinisa imihlahlandlela yokuvikela isiguli nokusebenzisa izixazululo zobuchwepheshe zokuqapha umlando wokuchayeka kwesiguli. Ngaphezu kwalokho, babuyekeze izinhlelo zamazwe ngamazwe okuhloswe ngazo ukuqhubeka nokuthuthukisa ukuvikeleka kwemisebe yeziguli.
“Nsuku zonke, izigidi zeziguli zihlomula ngezithombe zokuxilonga ezifana ne-computed tomography (CT), i-X-rays, (eqedwa ngemidiya ehlukile futhi ngokuvamile izinhlobo ezineama-injection aphezulu we-presspure: I-CT injection eyodwa, I-CT dual head injector, Umjovo we-MRI, futhiI-Angiography or Isijovo semidiya esihlukile se-DSA ephezulu(kuphinde kubizwe ngokuthi "cath lab"),kanye nesirinji namashubhu), kanye nezinqubo zokungenelela eziqondiswa yisithombe izinqubo zemithi yenuzi, kodwa ngokwanda kokusetshenziswa kwezithombe zemisebe kufika ukukhathazeka mayelana nokwanda okuhlobene nokuchayeka kwemisebe ezigulini, "kusho uPeter Johnston, uMqondisi we-IAEA Radiation, Uphiko lwezokuThutha nokuPhepha kukaDoti. "Kubalulekile ukusungula izindlela ezibambekayo zokuthuthukisa ukuthethelelwa kwesithombe esinjalo kanye nokwenza kahle kokuvikelwa kwemisebe esigulini ngasinye esithola ukwelashwa nokwelashwa okunjalo."
Emhlabeni jikelele, zingaphezu kwezigidigidi ezi-4 izinqubo zokuxilonga ze-radiological and nuclear medicine zenziwa minyaka yonke. Izinzuzo zalezi zinqubo zidlula kakhulu noma yiziphi izingozi zemisebe lapho zenziwa ngokuhambisana nokufaneleka komtholampilo, zisebenzisa ukuchayeka okuncane okudingekayo ukuze kufezwe imigomo edingekayo yokuxilonga noma yokwelapha.
Umthamo wokukhishwa kwemisebe obangelwa inqubo yokuthwebula ngayinye ngokuvamile uncane, ngokuvamile uhluka ukusuka ku-0.001 mSv ukuya ku-20-25 mSv, kuye ngohlobo lwenqubo. Leli zinga lokuchayeka lifana nemisebe yangemuva abantu abahlangabezana nayo ngokwemvelo phakathi nenkathi yezinsuku ezimbalwa kuya eminyakeni embalwa. UJenia Vassileva, Uchwepheshe Wokuvikelwa Kwemisebe kwa-IAEA, uxwayise ngokuthi izingozi ezingaba khona ezihlobene nemisebe zingase zikhule lapho isiguli senza uchungechunge lwezinqubo zokuthwebula izithombe ezihlanganisa ukuchayeka emisebeni, ikakhulukazi uma kwenzeka ngokulandelana eduze.
Ochwepheshe abangaphezu kuka-90 abavela emazweni angu-40, izinhlangano zamazwe ngamazwe ezingu-11 kanye nezinhlaka eziqeqeshiwe zihambele umhlangano kusukela mhla ziyi-19 kuya zingama-23 kuMfumfu. Abahlanganyeli bahlanganisa ochwepheshe bokuvikela imisebe, izazi ze-radiologists, odokotela bemithi yenuzi, odokotela, ochwepheshe bezokwelapha, ochwepheshe bemisebe, izazi ze-radiobiologist, izazi zezifo, abacwaningi, abakhiqizi nabameleli beziguli.
Ukulandelela ukuchayeka kwemisebe yeziguli
Amadokhumenti anemba futhi angaguquki, ukubika, nokuhlaziywa kwemithamo yemisebe etholwe iziguli ezikhungweni zezokwelapha kungathuthukisa ukuphathwa kwemithamo ngaphandle kokufaka engozini ulwazi lokuxilonga. Ukusebenzisa idatha erekhodiwe yokuhlolwa kwangaphambilini nemithamo elawulwayo kungadlala indima ebalulekile ekugwemeni ukuchayeka okungadingekile.
UMadan M. Rehani, uMqondisi weGlobal Outreach for Radiation Protection eMassachusetts General Hospital e-United States kanye noSihlalo womhlangano, uveze ukuthi ukusetshenziswa okwandisiwe kwezinhlelo zokuqapha ukuchayeka kwemisebe kunikeze idatha ephakamisa ukuthi inani leziguli eziqongelela umthamo osebenzayo I-100 mSv nangaphezulu phakathi neminyaka embalwa ngenxa yezinqubo ze-tomography yekhompuyutha ephindaphindayo iphezulu kunalokho obekucatshangwa ngaphambilini. Isilinganiso somhlaba simi ezigulini eziyisigidi ngonyaka. Ngaphezu kwalokho, ugcizelele ukuthi isiguli esisodwa kweziyisihlanu kulesi sigaba kulindeleke ukuthi sibe ngaphansi kweminyaka engu-50 ubudala, siphakamise ukukhathazeka ngemiphumela engase ibe khona emisebeni, ikakhulukazi kulabo abanesikhathi eside sokuphila kanye nethuba eliphakeme lokuba nomdlavuza ngenxa yokwanda kokuchayeka emisebeni.
Indlela eya Phambili
Abahlanganyeli bafinyelele ukuvumelana kokuthi kunesidingo sokusekelwa okuthuthukisiwe nokusebenza kahle kweziguli ezibhekene nezifo ezingelapheki nezimo ezidinga ukuthwebula izithombe njalo. Bavumelana ngokubaluleka kokusebenzisa kabanzi ukulandelela ukuchayeka emisebeni nokukuhlanganisa nezinye izinhlelo zolwazi lokunakekelwa kwezempilo ukuze kuzuzwe imiphumela emihle. Ngaphezu kwalokho, bagcizelele isidingo sokuqhubekisela phambili ukuthuthukiswa kwemishini yokuthwebula esebenzisa imithamo encishisiwe namathuluzi esoftware yokuqapha umthamo ojwayelekile wokusetshenziswa komhlaba wonke.
Kodwa-ke, ukusebenza kahle kwamathuluzi anjalo athuthukile akuncikile kuphela emishinini nasezinhlelweni ezithuthukisiwe, kodwa ekwazisweni kwabasebenzisi abafana nodokotela, izazi zefiziksi yezokwelapha, nochwepheshe. Ngakho-ke, kubalulekile kubo ukuba bathole ukuqeqeshwa okufanele kanye nolwazi lwakamuva mayelana nezingozi zemisebe, ukuhwebelana ngolwazi, futhi bahlanganyele ekuxoxisaneni okusobala neziguli nabanakekeli mayelana nezinzuzo nezingozi ezingaba khona.
