Ukushoda kwe-Helium kubangela umuzwa omusha wokuphuthuma emphakathini wokucabanga wezokwelapha

I-NBC News isanda kubika ukuthi ochwepheshe bezokunakekelwa kwempilo bakhathazeka kakhulu ngezwei-heliumukushoda kanye nomthelela wako emkhakheni we-imaging resonance magnetic.I-Heliumkubalulekile ukugcina umshini we-MRI upholile ngenkathi usebenza. Ngaphandle kwaso, isithwebuli asikwazi ukusebenza ngokuphepha. Kodwa eminyakeni yamuva, globali-heliumukunikezwa kudonse ukunaka okukhulu, futhi abanye abahlinzeki sebeqalile ukukala into engavuseleleki.

Nakuba lokhu sekuqhubeke iminyaka eyishumi noma ngaphezulu, umjikelezo wezindaba wakamuva ngesihloko ubonakala unezela umuzwa wokuphuthuma. Kodwa ngasiphi isizathu?

Njengezinkinga eziningi zokuhlinzekwa kwezidingo eminyakeni emithathu edlule, ubhubhane lushiye amamaki athile ekuhlinzekweni nasekusabalalisenii-helium. Impi yase-Ukraine nayo yaba nomthelela omkhulu ekuhlinzekweni kwei-helium. Kuze kube muva nje, iRussia bekulindeleke ukuthi inikeze cishe ingxenye yesithathu ye-helium yomhlaba esikhungweni esikhulu sokukhiqiza eSiberia, kodwa umlilo kulesi sikhungo wabambezela ukwethulwa kwalesi sikhungo futhi impi yaseRussia e-Ukraine iqhubekisele phambili ukukhulisa ubudlelwano bayo nobudlelwano bezohwebo baseMelika. . Zonke lezi zici ziyahlangana ukuze zibhebhethekise izinkinga ze-supply chain.

UPhil Kornbluth, umongameli weKornbluth Helium Consulting, wabelane ne-NBC News ukuthi i-US ihlinzeka ngamaphesenti angama-40 emhlabeni jikelele.i-helium, kodwa izingxenye ezine kwezinhlanu zabaphakeli abakhulu bezwe seziqalile ukukala. Njengabahlinzeki bempahla abasanda kungena ekushodeni kokuhluka kwe-iodine, abahlinzeki be-helium baphendukela kumasu okunciphisa ahlanganisa ukubeka izimboni phambili ezinezidingo ezibaluleke kakhulu, njengokunakekelwa kwezempilo. Lezi zinyathelo azikakahumusheki ekukhanselweni kokuhlolwa kwezithombe, kodwa sezibangele ukushaqeka okwaziwayo emphakathini wesayensi nocwaningo. Izinhlelo eziningi zocwaningo lwe-Harvard zivalwa ngokuphelele ngenxa yokushoda, futhi u-UC Davis usanda kwabelana ngokuthi omunye wabahlinzeki babo unqamule izibonelelo zabo ngesigamu, kungakhathaliseki ukuthi izinjongo zezokwelapha noma cha. Lolu daba seludonse amehlo nabakhiqizi be-MRI. Izinkampani ezifana ne-GE Healthcare kanye ne-Siemens Healthineers bezilokhu zenza amadivaysi asebenza kahle kakhulu futhi adinga kancanei-helium. Nokho, lezi zinqubo azikasetshenziswa kabanzi.
