Kuperewera kwa Helium kumabweretsa chidwi chatsopano m'magulu azachipatala

NBC News posachedwa inanena kuti akatswiri azaumoyo akuda nkhawa kwambiri padziko lonse lapansiheliumkusowa ndi zotsatira zake pazithunzi za maginito resonance.Heliumndikofunikira kuti makina a MRI azizizira pamene akuyenda. Popanda izo, sikaniyo sichitha kugwira ntchito bwino. Koma m'zaka zaposachedwa, padziko lonse lapansiheliumkupezeka kwakopa chidwi kwambiri, ndipo ogulitsa ena ayamba kugawa chinthu chosawonjezedwanso.

Ngakhale kuti izi zakhala zikuchitika kwa zaka khumi kapena kuposerapo, nkhani zaposachedwa pamutuwu zikuwoneka kuti zikuwonjezera chidwi. Koma n’chifukwa chiyani?

Monga momwe zilili ndi zovuta zambiri zopezeka m'zaka zitatu zapitazi, mliriwu wasiya chizindikiro pakupereka ndi kugawa kwahelium. Nkhondo yaku Ukraine idakhudzanso kwambiri kuperekedwa kwahelium. Mpaka posachedwa, Russia ikuyembekezeka kupereka gawo limodzi mwa magawo atatu a helium yapadziko lonse lapansi kuchokera ku malo akuluakulu opangira zinthu ku Siberia, koma moto pamalowo unachedwetsa kukhazikitsidwa kwa malowo ndipo nkhondo yaku Russia ku Ukraine yakulitsa ubale wake ndi mgwirizano wamalonda waku US. . Zinthu zonsezi zimaphatikizana ndikukulitsa zovuta zamtundu wamagetsi.

Phil Kornbluth, Purezidenti wa Kornbluth Helium Consulting, adagawana ndi NBC News kuti US imapereka pafupifupi 40 peresenti ya dziko lapansi.helium, koma magawo anayi mwa asanu mwa ogulitsa akuluakulu a dzikolo ayamba kugawa. Monga ogulitsa omwe akhudzidwa posachedwa ndi kuchepa kwa ayodini, othandizira a helium atembenukira ku njira zochepetsera zomwe zimaphatikizapo kuika patsogolo mafakitale omwe ali ndi zofunika kwambiri, monga chisamaliro chaumoyo. Kusunthaku sikunatanthauzirebe kuletsa mayeso oyerekeza, koma ayambitsa kale zododometsa zodziwika bwino kwa gulu lasayansi ndi kafukufuku. Mapulogalamu ambiri ofufuza a Harvard akutseka kwathunthu chifukwa cha kusowa, ndipo UC Davis posachedwa adagawana kuti m'modzi mwa omwe amawathandiza adadula ndalama zawo pakati, kaya ndi zamankhwala kapena ayi. Nkhaniyi yakopanso chidwi cha opanga MRI. Makampani monga GE Healthcare ndi Siemens Healthineers akhala akupanga zipangizo zomwe zimagwira ntchito bwino komanso zimafuna zochepahelium. Komabe, njirazi sizinagwiritsidwebe ntchito kwambiri.
