Kusowa kwa helium kwayambitsa chidwi chatsopano m'gulu la akatswiri ojambula zithunzi zachipatala

Posachedwapa NBC News inanena kuti akatswiri azaumoyo akuda nkhawa kwambiri ndi dziko lonse lapansiheliamukusowa kwa zinthu ndi momwe zimakhudzira luso la kujambula zithunzi pogwiritsa ntchito maginito.Heliumndikofunikira kuti makina a MRI azizizira pamene akugwira ntchito. Popanda izi, sikelo siingagwire ntchito bwino. Koma m'zaka zaposachedwapa, padziko lonse lapansiheliamuKupereka kwakopa chidwi cha anthu ambiri, ndipo ogulitsa ena ayamba kugawa chinthu chosabwezerezedwanso.

Ngakhale kuti izi zakhala zikuchitika kwa zaka khumi kapena kuposerapo, nkhani zaposachedwa kwambiri pankhaniyi zikuoneka kuti zikuwonjezera kufunika kwachangu. Koma chifukwa chiyani?

Monga momwe zilili ndi mavuto ambiri okhudzana ndi kupezeka kwa zinthu m'zaka zitatu zapitazi, mliriwu wasiya zizindikiro zina pa kupezeka ndi kufalikira kwa zinthuzi.heliamuNkhondo ya ku Ukraine inakhudzanso kwambiri kupezeka kwaheliamuMpaka posachedwapa, Russia inkayembekezera kupereka gawo limodzi mwa magawo atatu a helium padziko lonse lapansi kuchokera ku fakitale yayikulu yopanga zinthu ku Siberia, koma moto womwe unabuka pamalopo unachedwetsa kuyambitsidwa kwa fakitaleyo ndipo nkhondo ya Russia ku Ukraine yawonjezera ubale wake ndi ubale wamalonda ku US. Zonsezi zikuwonjezera mavuto okhudzana ndi unyolo woperekera zinthu.

Phil Kornbluth, purezidenti wa Kornbluth Helium Consulting, adagawana ndi NBC News kuti US ikupereka pafupifupi 40 peresenti ya ndalama zonse padziko lonse lapansi.heliamu, koma magawo anayi mwa asanu a ogulitsa akuluakulu mdziko muno ayamba kupereka magawo. Monga ogulitsa posachedwapa omwe akhudzidwa ndi kusowa kwa ayodini, ogulitsa helium akugwiritsa ntchito njira zochepetsera mavuto zomwe zikuphatikizapo kuyika patsogolo mafakitale omwe ali ndi zosowa zofunika kwambiri, monga chisamaliro chaumoyo. Izi sizinasinthebe kuti mayeso ojambulira zithunzi athetsedwe, koma zayambitsa kale zodabwitsa zina kwa asayansi ndi ofufuza. Mapulogalamu ambiri ofufuza ku Harvard akutsekedwa kwathunthu chifukwa cha kusowa, ndipo UC Davis posachedwapa adagawana kuti m'modzi mwa opereka chithandizo chawo adachepetsa ndalama zawo zothandizira pakati, kaya ndi zachipatala kapena ayi. Nkhaniyi yakopanso chidwi cha opanga MRI. Makampani monga GE Healthcare ndi Siemens Healthineers akhala akupanga zida zomwe zimagwira ntchito bwino komanso zimafuna zochepa.heliamuKomabe, njira zimenezi sizikugwiritsidwa ntchito kwambiri.
