Vhiki rino, IAEA yakaronga musangano wepamhepo wekutarisa kufambira mberi mukuderedza njodzi dzine chekuita nemwaranzi kune varwere vanoda mifananidzo yekurapa nguva nenguva, ukuwo vachiona kuti mabhenefiti akachengetedzwa. Pamusangano, vakapinda vakakurukura nzira dzekusimbisa nhungamiro dzekudzivirira varwere uye kushandisa mhinduro dzetekinoroji dzekutarisa nhoroondo yekusangana nevarwere. Uyezve, vakaongorora zvirongwa zvepasi rose zvakanangana nekusimudzira nguva dzose kuchengetedzwa kwemwaranzi kwevarwere.
"Zuva rega rega, mamiriyoni evarwere anobatsirwa nemifananidzo yekuongorora yakaita se computed tomography (CT), X-rays, (iyo inozadzwa ne contrast media uye kazhinji mhando ina dzemajekiseni akachena zvakanyanya: jekiseni reCT rimwe chete, jekiseni reCT remusoro miviri, Jekiseni reMRIuyeAngiography or DSA injector yemhando yepamusoro yeDSA(inonziwo “rabhoritari yekurapa“),uye mamwe masirinji nemachubhu), uye nzira dzinotungamirirwa nemifananidzo, nzira dzekurapa nenyuchi, asi nekushandiswa kwakawanda kwemifananidzo yemwaranzi kunouya kunetseka pamusoro pekuwedzera kwekushandiswa kwemwaranzi kuvarwere,” akadaro Peter Johnston, Mutungamiriri weIAEA Radiation, Transport and Waste Safety Division. “Zvakakosha kuisa matanho chaiwo ekuvandudza chikonzero chemifananidzo yakadaro uye kugadzirisa dziviriro yemwaranzi kumurwere wega wega ari kuongororwa nekurapwa kwakadaro.”
Pasi rose, nzira dzinopfuura mabhiriyoni mana dzekuongorora neradiology uye nyukireya dzinoitwa gore rega rega. Mabhenefiti enzira idzi anopfuura zvakanyanya njodzi dzemwaranzi kana dzichiitwa zvinoenderana nezvikonzero zvekiriniki, zvichiita kuti pave nekuratidzwa kushoma kunodiwa kuti zvizadzise zvinangwa zvekuongorora kana kurapa.
Chiyero chemwaranzi chinobva pakutorwa kwemifananidzo yemunhu mumwe nemumwe chinowanzova chidiki, chinowanzo siyana kubva pa0.001 mSv kusvika 20-25 mSv, zvichienderana nerudzi rwenzira yacho. Kuonekwa uku kwakafanana nemwaranzi yekumashure iyo vanhu vanosangana nayo kwemazuva akati wandei kusvika kumakore mashoma. Jenia Vassileva, Nyanzvi yeKudzivirira Mwaranzi kuIAEA, akanyevera kuti njodzi dzinogona kusanganisirwa nemwaranzi dzinogona kuwedzera kana murwere akaitwa mifananidzo yakawanda inosanganisira kuratidzwa nemwaranzi, kunyanya kana zvikaitika zviri pedyo.
Nyanzvi dzinopfuura makumi mapfumbamwe dzakabva kunyika makumi mana, masangano gumi nerimwe epasi rose nemasangano ehunyanzvi vakapinda musangano uyu kubva musi wa19 kusvika 23 Gumiguru. Vatori vechikamu vaisanganisira nyanzvi dzekudzivirira mwaranzi, vanachiremba veradiology, vanachiremba vemishonga yenyukireya, vanachiremba, nyanzvi dzefizikisi dzekurapa, nyanzvi dzemwaranzi, vanachiremba veradiobiologist, vanachiremba vezvirwere zvehutachiona, vaongorori, vagadziri nevamiriri vevarwere.
Kutevera kuratidzwa kwemwaranzi nevarwere
Zvinyorwa zvakarurama uye zvinoenderana, mishumo, uye kuongororwa kwemwaranzi inogamuchirwa nevarwere kuzvipatara zvinogona kuvandudza manejimendi yemwaranzi pasina kukanganisa ruzivo rwekuongorora. Kushandisa data rakanyorwa kubva mukuongororwa kwakapfuura uye madosi akapihwa kunogona kuita basa guru mukudzivirira kusangana nevarwere zvisina kufanira.
Madan M. Rehani, Mutungamiriri weGlobal Outreach for Radiation Protection kuMassachusetts General Hospital muUnited States uye Sachigaro wemusangano uyu, vakaburitsa pachena kuti kushandiswa kwakawanda kwenzira dzekutarisa kuratidzwa kwemwaranzi kwakapa data rinoratidza kuti huwandu hwevarwere vanounganidza dose inoshanda ye100 mSv zvichikwira mumakore akati wandei nekuda kwemaitiro e computed tomography anowanzo wedzerwa kupfuura zvaifungidzirwa kare. Kufungidzirwa kwepasi rose kuri pavarwere vane miriyoni imwe pagore. Uyezve, vakasimbisa kuti mumwe chete pavarwere vashanu vari muchikamu ichi anotarisirwa kunge ari pasi pemakore makumi mashanu ekuberekwa, zvichikonzera kushushikana pamusoro pemhedzisiro inogona kuitika yemwaranzi, kunyanya kune avo vane tarisiro yekurarama kwenguva refu uye mukana wepamusoro wekenza nekuda kwekuwedzera kwemwaranzi.
Nzira Yekumberi
Vatori vechikamu vakabvumirana kuti pane chikonzero chekubatsira varwere vane zvirwere zvisingaperi uye zvirwere zvinoda kuti vanhu vatore mifananidzo nguva nenguva. Vakabvumirana nezvekukosha kwekushandisa nzira dzakawanda dzekutevera njodzi yemwaranzi uye kuibatanidza nedzimwe nzira dzeruzivo rwehutano kuti vawane mhedzisiro yakanaka. Uyezve, vakasimbisa chinodiwa chekusimudzira kugadzirwa kwezvishandiso zvemifananidzo zvinoshandisa madosi akaderedzwa uye maturusi esoftware ekutarisa madosi akajairika kuti ashandiswe pasi rose.
Zvisinei, kushanda zvakanaka kwezvishandiso zvemhando yepamusoro izvi hakungobvi pamichina chete uye masisitimu akavandudzwa, asi pahunyanzvi hwevashandisi vakaita savanachiremba, nyanzvi dzefizikisi dzezvekurapa, uye matekiniki. Saka, zvakakosha kuti vawane kudzidziswa kwakakodzera uye ruzivo rwechizvino-zvino maererano nenjodzi dzemwaranzi, kuchinjana ruzivo, uye kuita kutaurirana pachena nevarwere nevanotarisira nezvezvakanakira nenjodzi dzingangoitika.
