Momwe mungadzitetezere ku radiation mumlengalenga

Australian National University (ANU) yapanga chida chatsopano chomwe chimatha kuwunikira kapena kufalitsa kuwala pakufunika ndipo chimayendetsedwa ndi kutentha. Malinga ndi olemba a kafukufukuyu, izi zimatsegula chitseko cha matekinoloje omwe amateteza astronauts mumlengalenga ku ma radiation oyipa.

Mtsogoleri wa Kafukufuku Mohsen Rahmani ANU idati zinthuzo zinali zoonda kwambiri kotero kuti mazana a zigawo zitha kugwiritsidwa ntchito pansonga ya singano, yomwe ingagwiritsidwe ntchito pamtunda uliwonse, kuphatikiza suti zamlengalenga.

Malire a ntchito mu millisieverts

Uwu ndi malingaliro ena onse komanso otalikirapo oti athane ndi kunyezimira koyipa komwe anthu amakumana nako kunja kwa mlengalenga wa Dziko Lapansi.

Zamoyo zimamva zoipa mumlengalenga. Kwenikweni, NASA imatanthauzira "malire a ntchito" kwa oyenda mumlengalenga, malinga ndi kuchuluka kwa ma radiation omwe amatha kuyamwa. Malire awa 800 mpaka 1200 millisievertskutengera zaka, jenda ndi zina. Mlingo uwu umafanana ndi chiopsezo chachikulu chokhala ndi khansa - 3%. NASA salola ngozi zambiri.

Pafupifupi anthu okhala padziko lapansi amakhala pafupifupi pafupifupi. 6 millisieverts ya radiation pachaka, zomwe zimakhala chifukwa cha zochitika zachilengedwe monga gasi wa radon ndi granite countertops, komanso kuwonetseredwa kwachilendo monga x-ray.

Maulendo a mumlengalenga, makamaka omwe ali kunja kwa mphamvu ya maginito ya Dziko lapansi, amakumana ndi ma radiation ambiri, kuphatikiza ma radiation ochokera ku mphepo yamkuntho yadzuwa yomwe imatha kuwononga mafupa ndi ziwalo. Choncho ngati tikufuna kuyenda mumlengalenga, tiyenera kulimbana ndi vuto la cheza cholimba cha cosmic.

Kuwonekera kwa radiation kumawonjezeranso chiwopsezo cha openda zakuthambo kukhala ndi mitundu ingapo ya khansa, kusintha kwa majini, kuwonongeka kwa dongosolo lamanjenje komanso ngakhale ng'ala. Pazaka makumi angapo zapitazi za pulogalamu ya mlengalenga, NASA yatolera zidziwitso zakukhudzana ndi ma radiation kwa okonda zakuthambo.

Pakali pano tilibe chitetezo chokhazikika ku cheza chakupha cha cosmic. Mayankho omwe aperekedwa amasiyana malinga ndi kagwiritsidwe ntchito dongo kuchokera ku asteroids monga chimakwirira, pambuyo nyumba zapansi panthaka pa Mars, yopangidwa kuchokera ku Martian regolith, koma malingaliro ake ndiachilendo komabe.

NASA ikufufuza dongosololi Kutetezedwa kwamunthu payekha pamaulendo apakatikati a ndege (PERSEO). Amaganiza kugwiritsa ntchito madzi ngati zinthu zachitukuko, zotetezeka ku radiation. ovololo. Chithunzichi chikuyesedwa mu International Space Station (ISS). Asayansi akuyesa, mwachitsanzo, ngati woyenda m’mlengalenga angathe kuvala bwinobwino suti ya m’mlengalenga yodzaza ndi madzi kenako n’kukhuthula popanda kuwononga madzi, amene ndi chinthu chofunika kwambiri m’mlengalenga.

Kampani ya Israeli ya StemRad ikufuna kuthetsa vutoli popereka chitetezo cha radiation. NASA ndi Israel Space Agency asayina pangano lomwe chida choteteza ma radiation cha AstroRad chidzagwiritsidwa ntchito panthawi ya NASA EM-1 mission kuzungulira Mwezi komanso ku International Space Station mu 2019.

Monga mbalame za Chernobyl

Popeza kuti zamoyo zimadziwika kuti zinayambira pa pulaneti lotetezedwa bwino ndi kuwala kwa dzuwa, zamoyo zapadziko lapansi sizingathe kukhalabe ndi moyo popanda chishangochi. Mtundu uliwonse wa chitukuko cha chitetezo chatsopano chachilengedwe, kuphatikizapo ma radiation, chimafuna nthawi yaitali. Komabe, pali zosiyana.

Nkhani yakuti "Kutsutsa wailesi kwanthawi yayitali!" pa tsamba la Oncotarget

Nkhani ya mu 2014 Science News inafotokoza mmene zamoyo zambiri za m’dera la Chernobyl zinawonongeka chifukwa cha ma radiation ambiri. Komabe, zidapezeka kuti m'magulu ena a mbalame izi sizili choncho. Ena ayamba kukana ma radiation, zomwe zimapangitsa kuti kuwonongeka kwa DNA kuchepe komanso kuchuluka kwa ma free radicals owopsa.

Lingaliro loti nyama sizimangotengera ma radiation okha, koma zimathanso kuyankha bwino, ndizothandiza ambiri kumvetsetsa momwe anthu angagwirizane ndi malo okhala ndi ma radiation ochulukirapo, monga chowulungika, pulaneti lachilendo, kapena interstellar. danga..

Mu February 2018, nkhani inatuluka m'magazini ya Oncotarget pansi pa mawu akuti "Vive la radiorésistance!" ("Moyo wautali wa radioimmunity!"). Idakhudzanso kafukufuku pankhani ya radiobiology ndi biogerontology yomwe cholinga chake chinali kukulitsa kukana kwa anthu ku radiation mumikhalidwe yakuzama kwa mlengalenga. Pakati pa olemba nkhaniyo, omwe cholinga chawo chinali kufotokoza "mapu a msewu" kuti akwaniritse chitetezo cha anthu ku mauthenga a wailesi, kulola kuti mitundu yathu ifufuze malo popanda mantha, ndi akatswiri ochokera ku NASA Ames Research Center.

 - adatero Joao Pedro de Magalhães, wolemba nawo nkhaniyo, woimira American Research Foundation for Biogerontology.

Malingaliro omwe amazungulira m'gulu la ochirikiza "kusintha" kwa thupi la munthu kupita ku zakuthambo akumveka ngati zosangalatsa. Mmodzi wa iwo, mwachitsanzo, adzakhala m'malo mwa zigawo zikuluzikulu za thupi lathu mapuloteni, zinthu haidrojeni ndi carbon, ndi olemera isotopes, deuterium ndi C-13 carbon. Palinso njira zina zodziwika bwino, monga mankhwala opangira katemera ndi radiation therapy, gene therapy, kapena kusinthika kwa minofu pama cell.

Inde, pali njira yosiyana kwambiri. Akuti ngati mlengalenga ndi wodana kwambiri ndi biology yathu, tiyeni tingokhala Padziko Lapansi ndikulola makina omwe sawononga kwambiri ma radiation afufuzidwe.

Komabe, maganizo amtunduwu akuwoneka kuti akusemphana kwambiri ndi maloto a anthu akale oyendayenda mumlengalenga.
