Kule veki, i-IAEA iququzelele intlanganiso ebonakalayo yokujongana nenkqubela phambili yokunciphisa imingcipheko enxulumene nemitha kwizigulana ezifuna ukubonwa rhoqo kwezonyango, ngelixa iqinisekisa ukugcinwa kwezibonelelo. Kwintlanganiso, ababekho baxoxa ngezicwangciso zokuqinisa izikhokelo zokukhusela isigulane kunye nokuphumeza izisombululo zeteknoloji zokubeka iliso kwimbali yokuvezwa kwesigulane. Ngaphaya koko, baye baphonononga amalinge ezizwe ngezizwe ajolise ekwandiseni ukhuseleko lwemitha yezigulana.
“Yonke imihla, izigidi zezigulana ziyazuza kwi-diagnostic yokuxilonga efana ne-computed tomography (CT), ii-X-rays, (egqityezelwa ngamajelo osasazo olwahlukileyo kwaye ngokubanzi ezine iintloboii-injector zoxinzelelo oluphezulu: CT injectior enye, CT isitofu sentloko ezimbini, Isitofu seMRI, kwayeI-Angiography or I-DSA yokuchasa uxinzelelo oluphezulu lwesitofu semidiya(ikwabizwa ngokuba "cath lab"),kunye nesirinji kunye neityhubhu), kunye neenkqubo zongenelelo ezikhokelwa ngumfanekiso, kodwa ngokunyuka kokusetyenziswa kwemithamo yemitha kuza inkxalabo malunga nokonyuka kokuvezwa kwemitha kwizigulana, utshilo uPeter Johnston, uMlawuli wecandelo le-IAEA Radiation, Transport and Waste Safety.
Kwihlabathi jikelele, ngaphezulu kwe-4 yeebhiliyoni zeenkqubo zokuxilonga ngeradiyoloji kunye nenyukliya ziqhutywa minyaka le. Izibonelelo zezi nkqubo zigqithisa kakhulu nayiphi na imingcipheko yokusasazeka kwemitha xa zisenziwa ngokuhambelana nesizathu seklinikhi, zisebenzisa i-exposure encinci efunekayo ukufezekisa iinjongo eziyimfuneko zokuxilonga okanye zonyango.
Idosi yokusasazeka ngemitha evela kwinkqubo yokucinga yomntu iqhele ukuba mncinci, iqhele ukuhluka ukusuka ku-0.001 mSv ukuya ku-20-25 mSv, kuxhomekeke kuhlobo lwenkqubo. Eli nqanaba lokuba sesichengeni liyafana nemvelaphi yokusasazeka kwemitha abantu ngokwendalo abadibana nayo kwisithuba seentsuku ezininzi ukuya kwiminyaka embalwa. UJenia Vassileva, iNgcali yoKhuseleko lweRadiation kwi-IAEA, walumkisa ukuba iingozi ezinokubakho ezinxulumene nemitha yemitha zinokunyuka xa isiguli sifumana uthotho lweenkqubo zokucinga ezibandakanya ukuvezwa kwemitha, ngakumbi ukuba zenzeke ngokulandelelana.
Ngaphezulu kweengcali ze-90 ezivela kumazwe angama-40, imibutho ye-11 yamazwe ngamazwe kunye namaqumrhu aqeqeshiweyo azimase intlanganiso ukusuka kwi-19 ukuya kwi-23 ka-Oktobha. Abathathi-nxaxheba baquka iingcaphephe zokhuseleko lokusasazeka kwemitha, iingcali ngemitha, oogqirha bamayeza enyukliya, oogqirha, iingcali zonyango, iiteknoloji ngemitha, iradiobiologists, i-epidemiologists, abaphandi, abavelisi kunye nabameli bezigulane.
Ukulandelela ukuba sesichengeni ngemitha yezigulane
Amaxwebhu achanekileyo kunye angaguqukiyo, ukunika ingxelo, kunye nohlalutyo lweedosi zemitha ezifunyenwe zizigulane kumaziko onyango kunokuphucula ulawulo lweedosi ngaphandle kokuphazamisa ulwazi lokuxilonga. Ukusebenzisa idatha erekhodiweyo evela kwiimviwo zangaphambili kunye needosi ezilawulwayo kunokudlala indima ephambili ekuthinteleni ukutyhileka okungeyomfuneko.
UMadan M. Rehani, uMlawuli weGlobal Outreach for Radiation Protection eMassachusetts General Hospital eUnited States kunye noSihlalo wentlanganiso, udize ukuba ukusetyenziswa okwandisiweyo kweenkqubo zokubeka iliso kwi-radiation exposure kubonelele ngedatha ecebisa ukuba inani lezigulane eziqokelela idosi esebenzayo ye-100 mSv nangaphezulu kwiminyaka eliqela ngenxa yenkqubo ye-tomography ephindaphindiweyo iphezulu kunokuba bekuqikelelwa ngaphambili. Uqikelelo lwehlabathi limi kwisigidi sezigulane ngonyaka. Ngaphaya koko, ugxininise ukuba esinye kwisigulana esihlanu kolu didi kulindeleke ukuba sibengaphantsi kweminyaka engama-50 ubudala, siphakamisa inkxalabo malunga neziphumo ezinokubakho ngemitha, ngakumbi kwabo baphila ixesha elide kunye nokuba nokwenzeka okuphezulu komhlaza ngenxa yokwanda kokuvezwa kwemitha.
Indlela eya Phambili
Abathathi-nxaxheba bafikelele kwimvumelwano yokuba kukho imfuneko yokuphucula kunye nenkxaso efanelekileyo kwizigulane ezijongene nezifo ezingapheliyo kunye neemeko ezifuna ukucinga rhoqo. Baye bavumelana ngokubaluleka kokuphumeza ngokubanzi umkhondo wokuvezwa kokusasazeka kwemitha kunye nokudibanisa kunye nezinye iinkqubo zolwazi lwezempilo ukuphumeza iziphumo ezizezona zilungileyo. Ngaphaya koko, bagxininise imfuno yokuqhubela phambili uphuhliso lwezixhobo zokucinga ezisebenzisa iidosi ezincitshisiweyo kunye nedosi esemgangathweni yezixhobo zesoftware yokubeka iliso kwisicelo sehlabathi.
Nangona kunjalo, ukusebenza kwezi zixhobo zikumgangatho ophezulu akuxhomekekanga kuphela koomatshini kunye neenkqubo eziphuculweyo, kodwa kubuchule babasebenzisi abafana noogqirha, iingcali zonyango, kunye neengcali. Ke ngoko, kubalulekile kubo ukuba bafumane uqeqesho olufanelekileyo kunye nolwazi oluhlaziyiweyo malunga nemingcipheko yokusasazeka kwemitha, ukutshintshiselana ngobuchule, kwaye babandakanyeke kunxibelelwano oluselubala nezigulana kunye nabo babakhathalelayo malunga nezinto eziluncedo kunye neengozi ezinokubakho.
