Zithini iingozi zeX-reyi xa ukhulelwe?
Umxholo
- Itheyibhile yemitha ngohlobo lweX-ray
- Ngaba kuyingozi ukuba ne-x-ray ungazi ukuba ukhulelwe?
- Yintoni enokwenzeka ukuba ubhentsiswe kwimitha engaphezulu kunokuba ucetyisiwe
Umngcipheko omkhulu wokuba i-X-ray ithathwe ngexesha lokukhulelwa inxulumene namathuba okubangela iziphene zemfuza kwimveku, enokubangela izifo okanye ukungalunganga. Nangona kunjalo, le ngxaki inqabile kuba ifuna isixa esikhulu kakhulu semitha ebangela utshintsho kwimveku engekazalwa.
Ngokubanzi, eyona radiation iphakanyisiweyo ngexesha lokukhulelwa yile Iirandi ezi-5okanye i-5000 millirads, eyiyunithi esetyenziselwa ukulinganisa ubungakanani bemitha efunxweyo, kuba kweli xabiso usana olungekazalwa lunokutshintsha.
Nangona kunjalo, uninzi lweemviwo ezisebenzisa ii-X-ray zikude ekufikeleleni kwelona xabiso liphezulu, zithathwa ngokuba zikhuselekile ngokugqithileyo, ngakumbi ukuba ngaba uvavanyo lwe-1 ukuya kwezi-2 kuphela lwenziwa ngexesha lokukhulelwa.
Itheyibhile yemitha ngohlobo lweX-ray
Kuxhomekeka kwindawo apho umzimba uthathwa khona i-X-ray, inani lemitha liyahluka:
| Indawo yoviwo lwe-X-ray | Ubungakanani bemitha evela kuvavanyo (millirads *) | Zingaphi ii-x-reyi anokuzenza umntu okhulelweyo? |
| X-ray yomlomo | 0,1 | 50,000 |
| X-reyi yekhakhayi | 0,05 | 100 lamawaka |
| I-X-ray yesifuba | 200 ukuya ku-700 | 7 ukuya ku-25 |
| X-ray esiswini | 150 ukuya ku-400 | 12 ukuya ku-33 |
| I-X-ray yomqolo wesibeleko | 2 | 2500 |
| I-X-ray yomqolo wesisu | 9 | 550 |
| I-X-ray ye-lumbar spine | 200 ukuya ku-1000 | 5 ukuya ku-25 |
| X-ray okhalweni | 110 ukuya ku-400 | 12 ukuya ku-40 |
| I-X-ray yebele (mammogram) | 20 ukuya ku-70 | 70 ukuya ku-250 |
I-millilads ezili-1000 = 1 irad
Ke, umfazi okhulelweyo angenza iX-reyi nanini na xa kucetyiswa, kuyacetyiswa ukuba wazise ugqirha malunga nokukhulelwa, ukuze ifaskoti ekhokelayo esetyenziselwa ukukhusela imitha ibekwe ngokuchanekileyo kwisisu somfazi okhulelweyo.
Ngaba kuyingozi ukuba ne-x-ray ungazi ukuba ukhulelwe?
Kwimeko apho umfazi wayengazi ukuba ukhulelwe kwaye une-X-ray, uvavanyo alunabungozi, kwanasekuqaleni kokukhulelwa xa umbungu usakhula.
Nangona kunjalo, kuyacetyiswa ukuba, akuba nje efumene ukukhulelwa, owasetyhini wazise ugqirha malunga nenani leemvavanyo azenzileyo, ukuze inani lemitha esele lifunyiwe libaliwe, kuthintelwe ukuba lonke ixesha lokukhulelwa akufumanayo ngaphezulu kwe-5 rads.
Yintoni enokwenzeka ukuba ubhentsiswe kwimitha engaphezulu kunokuba ucetyisiwe
Iziphene kunye nokungalunganga okunokubonakala kwimveku engekazalwa kuyahluka ngokweminyaka yokukhulelwa, kunye nenani elipheleleyo lemitha ebonakaliswe ngumfazi okhulelweyo. Nangona kunjalo, xa kusenzeka, eyona ngxaki iphambili yokuvezwa kwemitha ngexesha lokukhulelwa kuhlala kusisi sifo somhlaza ngexesha lobuntwana.
Ke ngoko, iintsana ezizalwe emva kokuvezwa okukhulu kwimitha kufuneka zivavanywe rhoqo ngugqirha wabantwana, zichonge utshintsho kwangoko kwaye ziqale nonyango oluthile, ukuba kukho imfuneko yoko.
