Owai la ka mea ike i ka kŰia o ka radioactivity, a pehea ia i hiki mai ai?

I ka 'atikala e haʻi ana i ka poe i loaa i ka kŰia o radioactivity, ka wā e hiki mai ai, a ma lalo o ka noho ana.

radioactivity

ʻO kēia ao, a me ka oihana meaʻaʻole paha ia e hiki ke hana me ka nukelea ikehu. Nukelea reactors hānai poʻomanaʻo,, hoakaka uila i holoʻokoʻa kulanakauhale, a me kona poe ikehu kumu ka nānā 'ana ma luna o radioactive palaho, kaa i ukali a me robots mea eʻimi ana Ű.

Radioactivity i ike i ka hopena o XIX kenekulia. Eia naʻe, e like he nui 'ē aʻe nui discoveries i loko o kekahi mau kihapai o ka' epekema. Akā, ka mea i waena o kānakaʻepekema mua ike i ka kŰia o ka radioactivity, a pehea ia i hiki mai ai? Kēia ka mea a mākou e kamaʻilio i loko o kēia 'atikala.

Kaka

He nui loa no ka 'epekema hanana i wahi i ka 1896, a i kona Becquerel i loko o këia ka hiki pilina o ka luminescence, a me ka Puhi iho loaa ai-kapa X-Ray.

E like me na memoirs o Becquerel, i loaa i ka manaʻo e paha i kekahi luminescence ua pu ia e ka X-kukuna? I mea e hōʻoia i kona kohu, oia hoʻohana mau Nine Inch i huiʻia, a me kekahi o na paʻakai o ka uranium, a glows i loko o ka pouli. Eia, e paʻa ana ia i loko o ka la, i ke nä känaka 'epekema huli ka paʻakai i loko o ka pouli, pepa, a waiho ia i loko o ke keena mehameha ma luna o kekahi kiʻi pā, a, ma ka huli, ua kekahi ua pūʻolo helu ma ka opaque wrapper. Ma hope, ae hōʻike ana i kona Becquerel replaces he pololei portrayal o kekahi'āpana o ka paakai. Akā, mahope mai o ka luminescence o ka pepa hiki ole lanakila, ka mea, 'o ia hoʻi i ka mea, puka mai una X-Ray ea puka. No laila, ano, ua ike ka poe mua ike i ka kŰia o ka radioactivity. Eia naʻe, i ike i ka mea a ke loaʻa i. Ke nä känaka 'epekema i aole i hiki maopopo Akā, mua na mea mua.

I ka halawai ana o ka Academy o Sciences

Hope i keia makahiki, ma ka halawai o ka Academy o Sciences o Paris, Becquerel i ka hoike "Ma ka pāhawewe hua mai la ma ka phosphorescence." Akā, ma hope o ka manawa i loko o kona kumumanaʻo a me ka hoʻoholo 'mākou i ka hana i ka hoʻoponopono'. No ka laʻana, i kekahi o nā ho'āʻo ma, me ke kali ana no ka maikai a me ka ua pń mai auanei, ke nä känaka 'epekema kau ma luna o ke kiʻi pā uranium hui i ua ole irradiated me ka malamalama. Aka hoi, i ka mooolelo ua nō maopopo lewa i loko o kona 'ole.

Ma March o ka hookahi makahiki Becquerel hooku iho la ia i ke anaina kanaka o ka Academy o Sciences no ka hou 'oihana, ka mooolelo o ka pāhawewe kinoea ma ka phosphorescent kino. Ano, ua ike i o nā kānakaʻepekema loaa ka kŰia o ka radioactivity.

hou ia mea

Alualu hou haʻawina o ka kŰia o radioactivity, Becquerel ho'āʻo nui 'ona, me uranium mea hiki ke hooheheeia. A me na manawa i ka una honua mau noho ko läkou '. A ma kau ma waena o ka pāhawewe kumu, a me ka pā metala kea, ke nä känaka 'epekema loaa mai me mākou e olelo i keia la, i kona X-Ray. No laila mākou i ana no ka ninau o ka poe i loaa i ka kŰia o ka radioactivity.

A i ka wa e lilo ai maopopo i Becquerel loaa i ka loa houʻano o kaʻike makaʻole kukuna e hiki ke hele aku ma kekahi mea, akā, i ka mea ia manawa, ka mea, ua i X-Ray.

Ua pū i loaʻa ia i ka nui o ka pāhawewe hilinaʻi nui ma luna o ka nui o ka uranium i loko o Nine Inch hoomakaukau,ʻaʻole ma ko lākou mau? Ueo. It Becquerel kaʻana i kona akeakamai e piʻi like a me theories me kā lākou mau noho male, Pierre a me Mariey Kyuri, ka mea hope i hoʻokumu i ka radioactivity kinoea ma ka thorium, a wehe aʻela ia i nā momoku ahi hou hehee ai, ma hope o ka inoa polonium a me ka radium. A i ka wā ina hookolokolo i ka pilikia o "ka poe i loaa i ka kŰia o radioactivity," pinepine nui kuhihewa E hoomana aku i kēia kānaka apau i mākaukau Curies.

Hopena i ola meaola

I ka ikea ae la ia i ka radioactive pāhawewe kinoea a pau i huiʻia o ka uranium, Becquerel ua hoʻi hou i ka phosphor mahele. Akā, hana iho la oia i kekahi mea nui loaʻa - i ka hopena o radioactive kukuna ma liluwelo meaola. ole wale Pela Becquerel i ka mea mua i loaa i ka kŰia o radioactivity, akā, i ka poe i hoʻokumu i kona aoao i mea ola.

No kekahi o nā haʻi'ōlelo ia aie i ka radioactive waiwai i loko o ka Curies, a waiho ia i loko o kona eke. Ma hope o ka haʻi'ōlelo, hoi aku la i kona mea nona, ke nä känaka 'epekema i kekahi i kekahi ikaika kauluwela o kaʻili, a i keʻano o nā paipu. Pierre Curie lohe i kona koho hoʻoholo ihola e hoʻokolohua - no ka umi hola ua hoʻokomoʻia i hīkiʻiʻia ma ka lima şarkı i loaʻa radium. A ma ka hopena lawe au i ka ulcer ikaika i ka mea e hoola no kekahi mau mahina.

No laila mākou i ana no ka ninau o ka mea i waena o kānakaʻepekema mua ike i ka kŰia o ka radioactivity. Keia mea ana i ka aoao o ka radioactivity i ike ma liluwelo meaola. Akā, mamua o keia, no ka Curies, ma ke alanui, hoʻomau i ke komo i loko o ke ao o radioactive mea, a me ka Mariya Kyuri make o ka pāhawewe maʻi nei. ʻO kona kino, no ka mea, noho iho ia i loko o ka hana alakai, i kūʻai, no ka mea pāhawewe mahele lāʻau loaa ma ia mea kokoke i ka haneri makahiki aku nei mea nō oi pilikia loa.
