Pehea e pale ai iā ʻoe iho mai ka radiation ma ka lewa

Ua hoʻomohala ka Australian National University (ANU) i kahi nanomaterial hou e hiki ke hoʻohālikelike a hoʻouna paha i ka kukui ma ke koi a mālama ʻia ka mahana. Wahi a nā mea kākau o ke aʻo ʻana, wehe kēia i ka puka no nā ʻenehana e pale ai i nā astronauts ma ka lewa mai ka radiation pōʻino.

Poo o ka Imi Mohsen Rahmani Ua ʻōlelo ka ANU he lahilahi loa ka mea i hiki ke hoʻopili ʻia nā haneli he nui i ka piko o ka nila, hiki ke hoʻopili ʻia i kēlā me kēia ʻili, me nā lole ākea.

 Ua haʻi aku ʻo Kauka Rahmani iā ​​Science Daily.

 Hoʻohui ʻia ʻo Dr. Xu mai ka Center for Nonlinear Physics ma ke kula ANU o Physics and Engineering.

Laʻana o ka nanomaterial mai ANU ma lalo o ka hoʻāʻo ʻana

Ka palena o ka hana ma millisieverts

ʻO kēia kekahi pūʻulu manaʻo holoʻokoʻa a lōʻihi loa e hakakā a pale aku i nā kukuna cosmic pōʻino i ʻike ʻia e ke kanaka ma waho o ka lewa o ka Honua.

ʻino nā mea ola ma ka lewa. ʻO ka mea nui, wehewehe ʻo NASA i nā "palena hana" no nā astronauts, ma ke ʻano o ka nui o ka radiation hiki iā lākou ke komo. ʻO kēia palena 800 a 1200 millisievertsma muli o ka makahiki, ke kāne a me nā mea ʻē aʻe. ʻO kēia maʻi e pili ana i ka nui o ka pilikia o ka hoʻomohala ʻana i ka maʻi kanesa - 3%. ʻAʻole ʻae ʻo NASA i ka pilikia hou aʻe.

ʻIke ʻia ka awelika o ka poʻe noho o ka Honua ma kahi kokoke. 6 millisieverts o ka radiation i kēlā me kēia makahiki, ʻo ia ka hopena o nā hōʻike kūlohelohe e like me ka radon gas a me nā countertops granite, a me nā hōʻike kūlohelohe ʻole e like me nā x-ray.

Hōʻike ʻia nā mikiona lewa, ʻoi aku ka poʻe ma waho o ke kahua magnetic o ka Honua, i nā pae kiʻekiʻe o ka radiation, me ka radiation mai nā ʻino o ka lā i hiki ke hōʻino i ka iwi iwi a me nā kino. No laila inā makemake mākou e huakaʻi i ka lewa, pono mākou e hana i ka ʻoiaʻiʻo paʻakikī o nā kukuna cosmic paʻakikī.

Hoʻonui pū ka hoʻolaha ʻana i ka radiation i ka pilikia o nā astronauts e ulu ana i nā ʻano maʻi kanesa, nā hoʻololi genetic, nā pōʻino i ka ʻōnaehana nerve a me nā cataracts. I nā makahiki i hala iho nei o ka papahana lewa, ua hōʻiliʻili ʻo NASA i ka ʻikepili hōʻike radiation no kāna mau astronauts āpau.

I kēia manawa, ʻaʻohe o mākou palekana e kūʻē i nā kukuna lethal cosmic. ʻOkoʻa nā haʻina i manaʻo ʻia mai ka hoʻohana ʻana pālolo mai nā asteroids e like me nā uhi, ma hope hale ma lalo o ka honua ma mars, i hana ʻia mai Martian regolith, akā nani naʻe nā manaʻo.

Ke noiʻi nei ʻo NASA i ka ʻōnaehana Ka pale ʻana i ka radiation pilikino no nā mokulele interplanetary (PERSEO). Manaʻo i ka hoʻohana ʻana i ka wai ma ke ʻano he mea hoʻomohala, palekana mai ka radiation. lele. Ke hoʻāʻo ʻia nei ka prototype ma luna o ka International Space Station (ISS). Ke hoʻāʻo nei ka poʻe ʻepekema, no ka laʻana, inā hiki i kahi astronaut ke ʻaʻahu ʻoluʻolu i ka lole lumi piha i ka wai a laila hoʻokahe ʻole me ka pau ʻole o ka wai, he waiwai nui loa ia ma ka lewa.

Makemake ka hui Israeli StemRad e hoʻoponopono i ka pilikia ma ka hāʻawi ʻana pale radiation. Ua hoʻopaʻa inoa ʻo NASA a me ka Israel Space Agency i kahi ʻaelike e hoʻohana ʻia ai ka AstroRad radiation protection vest i ka wā o ka misionari NASA EM-1 a puni ka mahina a ma ka International Space Station ma 2019.

E like me nā manu Chernobyl

No ka mea, ua ʻike ʻia ua hoʻokumu ʻia ke ola ma luna o ka honua i pale pono ʻia mai ka radiation cosmic, ʻaʻole hiki i nā mea ola honua ke ola me ka ʻole o kēia pale. ʻO kēlā me kēia ʻano o ka hoʻomohala ʻana i kahi pale kūlohelohe hou, me ka radiation, pono ka manawa lōʻihi. Eia naʻe, aia kekahi mau ʻokoʻa.

ʻO ka ʻatikala "E ola mau ke kū'ē lekiō!" ma ka pūnaewele Oncotarget

Ua wehewehe ʻia kahi ʻatikala 2014 Science News i ka pōʻino o ka hapa nui o nā mea ola ma ka ʻāina ʻo Chernobyl ma muli o ke kiʻekiʻe o ka radiation. Eia naʻe, ua ʻike ʻia ʻaʻole pēlā ma kekahi mau manu. Ua hoʻomohala kekahi o lākou i ke kūʻē ʻana i ka radiation, e hoʻemi ana i nā pae o ka pōʻino DNA a me ka nui o nā radical manuahi weliweli.

ʻO ka manaʻo ʻaʻole hiki i nā holoholona ke hoʻololi wale i ka radiation, akā hiki ke hoʻomohala i kahi pane maikaʻi iā ia, no nā mea he nui ke kī i ka hoʻomaopopo ʻana pehea e hiki ai i ke kanaka ke hoʻololi i nā kaiapuni me nā pae kiʻekiʻe o ka radiation, e like me ka mokulele, kahi honua malihini, a i ʻole interstellar. kaawale. .

I Pepeluali 2018, ua puka mai kahi ʻatikala ma Oncotarget magazine ma lalo o ka slogan "Vive la radiorésistance!" (“E ola mau ka radioimmunity!”). Ua pili ia i ka noiʻi ʻana ma ke kahua o ka radiobiology a me ka biogerontology e kuhikuhi ana i ka hoʻonui ʻana i ke kūʻē ʻana o ke kanaka i ka radiation i nā kūlana o ka colonization hohonu. Ma waena o nā mea kākau o ka ʻatikala, nona ka pahuhopu e wehewehe i kahi "palapala alanui" e hoʻokō ai i kahi kūlana o ka pale ʻana o ke kanaka i ka hoʻokuʻu ʻana i ka lekiō, e ʻae ana i kā mākou ʻano e ʻimi i ka lewa me ka makaʻu ʻole, he mau loea mai ka NASA's Ames Research Center.

 - wahi a Joao Pedro de Magalhães, ka mea kākau o ka ʻatikala, ʻelele o ka American Research Foundation for Biogerontology.

ʻO nā manaʻo e holo nei i loko o ke kaiāulu o ka poʻe kākoʻo i ka "hoʻololi" o ke kino o ke kanaka i ka cosmos kani ʻano kupaianaha. ʻO kekahi o lākou, no ka laʻana, ʻo ia ke pani ʻana i nā mea nui o nā protein o ko mākou kino, nā mea hydrogen a me carbon, me kā lākou isotopes kaumaha, deuterium a me C-13 carbon. Aia kekahi mau ʻano hana ʻē aʻe, e like me nā lāʻau lapaʻau no ka pale ʻana me ka radiation therapy, gene therapy, a i ʻole ka hoʻoulu hou ʻana o ka ʻiʻo ma ka pae kelepona.

ʻOiaʻiʻo, aia kahi ʻano ʻokoʻa loa. Ua ʻōlelo ʻo ia inā ʻaʻole ʻino loa ka lewa i ko kākou biology, e noho wale kākou ma ka Honua a e ʻimi ʻia nā mīkini i emi ʻole ka pōʻino i ka radiation.

Eia nō naʻe, ʻano kūʻē loa kēia ʻano manaʻo me nā moeʻuhane o ka poʻe kahiko no ka huakaʻi lewa.
