NBC News munguva pfupi yapfuura yakashuma kuti nyanzvi dzehutano dziri kuwedzera kunetseka nezvepasireseheliumkushomeka uye kukanganisa kwayo pamunda wemagnetic resonance imaging.Heliumzvakakosha kuchengetedza muchina weMRI uchitonhorera uchiri kushanda. Pasina iyo, scanner haigone kushanda zvakachengeteka. Asi mumakore achangopfuura, pasi roseheliumkugovera kwakwezva kutarisisa kwakawanda, uye vamwe vatengesi vatanga kugovera chinhu chisinga vandudzwe.
Kunyangwe izvi zvave zvichiitika kwemakore gumi kana kupfuura, kutenderera kwenhau kwezvino pamusoro wenyaya kunoratidzika kunge kuri kuwedzera pfungwa yekukurumidzira. Asi nechikonzero chei?
Sezvinoita matambudziko mazhinji ekupa mukati memakore matatu apfuura, denda rakasiya mamwe mamaki pakugovera nekugoverahelium. Hondo yeUkraine zvakare yakave nekukanganisa kukuru pakupihwa kwehelium. Kusvika nguva pfupi yadarika, Russia yaitarisirwa kupa yakawanda senge chetatu chehelium yenyika kubva kune yakakura kugadzirwa nzvimbo muSiberia, asi moto panzvimbo iyi wakanonoka kutanga kwenzvimbo uye hondo yeRussia muUkraine yakawedzera hukama hwayo nehukama hwekutengeserana hweUS. . Zvese izvi zvinhu zvinosanganisa kuwedzera matambudziko ekupa cheni.
Phil Kornbluth, purezidhendi weKornbluth Helium Consulting, akagovana neNBC Nhau kuti US inopa zvikamu makumi mana muzana zvepasirese.helium, asi zvikamu zvina muzvishanu zvevatengesi vakuru venyika vatanga kugovera. Kufanana nevatengesi vachangobva kupinda mukushomeka kweiodine mutsauko, vatengesi vehelium vari kutendeukira kunzira dzekudzikisa dzinosanganisira kukoshesa maindasitiri ane zvinonyanya kukosha, senge hutano hwehutano. Matanho aya haasati aturikira mukukanzurwa kwebvunzo dzekufungidzira, asi akatokonzeresa zvinokatyamadza zvinozivikanwa kunharaunda yesainzi uye yekutsvagisa. Zvirongwa zvakawanda zveHarvard zvekutsvagisa zviri kuvharika zvachose nekuda kwekushomeka, uye UC Davis nguva pfupi yadarika akagovana kuti mumwe wevanopa wavo akacheka mari yavo nepakati, ingave yekurapa kana kwete. Nyaya iyi yabatawo pfungwa dzevagadziri veMRI. Makambani akadai seGE Healthcare neSiemens Healthineers anga achigadzira michina inoshanda zvakanyanya uye inoda zvishomahelium. Zvisinei, maitiro aya haasati ashandiswa zvakanyanya.
