Ano o ka pāhawewe.

Kēia manawa, ua ike ekolu ano o radioactive pāhawewe: Alpha, Hoʻokolohua, gamma.

Pehea e ka mea hana i?

A pau o ka mea ma luna o ke ano o ka pāhawewe i ka huina hoonui o ka hoʻopöʻino 'ia o isotopes o ka poe noonoo ole' ona. Nā'ātoma o ka oihana mua i haku o ka nucleus a me electrons, i ka ao ka a puni ia. Ke nucleus o ka'Ātoma mea i emi ma mua o hoʻokahi haneri tausani manawa, akā, ma muli o ia i ka pa apŘ like kiʻekiʻe, kona nuipa a mea kokoke like me ka huina nui o ka'Ātoma. I ka haku mele 'ana o nā nuclei i olelo ikaika mai, papa mai (particles) - protons a me neutrons me ka pila nui kauoha. A me ka poe a me kekahi poe e ae i ua hoʻopili i kekahi i kekahi loa mai iā ia. I ka helu ana o protons ma ka nucleus a me ka hooholo ia i mau Nine Inch hehee ai ʻeleu'Ātoma kikowaena, no kekahi laʻana, - 1 proton i loko o ka nucleus ka hydrogen protons 8 - oxygen ma 92 protons - uranium. I ka helu ana o electrons i loko o ka'Ātoma hoʻopili like me ka helu ana o protons i loko o kona nucleus. Kēlā me kēia huina'ine ka hoʻomaopop 'ana i io uila kauoha like me ka malama ana o ka proton, no keia mea, nohona ma'ākilikai'Ātoma.

Ka poe nā'ātoma nei ke ao hookahi nucleus ka helu o protons, akā, okoa neutron helu, e Lolina o ka ia Nine Inch waiwai, a kapa aku la kona isotopes. I mea e somehow maopopo ia lakou i ke ano o ka hehee ai, kaila i ka helu ana o ka huina o ka a pau na (particles) i loko o ka nucleus o keia kālaiōewe. No ka laʻana, ka mea kāna mau 'ōlelo hehee ai 238 ka loaʻa o 92 protons a me neutrons 146, a me ka uranium-235, i ka ia 92 protons, neutrons akā, ua 143. Most lolelua ka isotopes. No ka laʻana, uranium-238, kamailio ma waena o nā protons a me neutrons ma ka nucleus ka loa nawaliwali, a e ma neia hope aku, mai ka mea hoʻokaʻawale i ka olelo hoopomaikai pa alima iloko olaila no ka paʻa o ka neutron a me ka proton mau, e hoano hou ana uranium 238 i loko o ka 'ē hehee ai - thorium-234 mea i lolelua ka hehee ai, ka kāna mau 'ōlelo a iloko ona i kakauia 144 neutrons a me 90 protons. Ua mau kona palaho kaula reactions i alakai'Ātoma hana i ka holo ana. I loko o kēlā o kēia mau palaho ikehu ua hookuu, hoʻomakaʻia nāʻano likeʻole o radioactive radiations.

Inā 'oe Nohie i ke kulana, a laila, ua hiki ke wehewehe i ka muli o keʻano o ke pāhawewe:, alpha kukuna kī ana i kāna mau' ōlelo e ninoieo o ka paʻa o nā neutrons a me ka mau o protons, Hoʻokolohua-na kukuna emanate mai o ka huina'ine. Akā, he mau wahi, i hiki ai i ka kālaiōewe mea e inu nei no laila, i ka (particles) e loa mai o kona, aole ia e stabilize, a lailaʻo ia i loko o Ka Wailele O kekahi hapa oi ikehu maemae, ua kapaia gamma pāhawewe keia kaʻina. Kēia mau 'ano o ka pāhawewe e like me gamma kukuna, X-Ray a me ka e like, e hana me ke ea puka mea (particles). Ka manawa koi 'ia no ka palaho hapalua o na nā'ātoma a pau o kekahi haawiia kālaiōewe i loko o kekahi radioactive kumu, haawiia keia i like me ka hapalua kona ola. Ke kaʻina hana o ka nukelea loli 'o ke ana, a me kona aayoaeuiinoe ana nui' ia no ka lua o nāwaliwali aʻela, a ua anaia mai ka manawa i loko o becquerels (1'Ātoma no kekona).

Kekahi mau 'ano o ka pāhawewe i wehewehe aku ma ke kala ana o kaʻokoʻa nui o ka ikaika a me ka mana penetrating ka mea, i kekahi okoa, no laila, ke'aʻaʻa o ola meaola, ka mea i hana okoa.

Alpha pāhawewe, i mea he kahawai o kaumaha (particles) e paa oia i ka pepa o ka pepa, e mea hiki ole ke komo iloko o ka, ahu iho o ka make epidermal keena. Ia mea i nā palapala like loa me kekahi mau kumuhana e hoʻokuʻu akula, alpha (particles) e e komo i loko o ke kino ma eha a ma ka ai a me / ai ana lewa. A i ka wa e lilo loa pilikia loa.

Hoʻokolohua pāhawewe mea hiki ke komo iloko 1-2 kenimika ma ka noho ana'aʻaʻa.

Gamma kukuna, a hele ma ka mämä holo o ka malamalama, i ka noho pilikia loa, a me ka mea hiki ke hoʻopaneʻe wale i ke ao slab o ke kēpau paha pōhaku puna.

A pau 'ano o ka pāhawewe hiki i ka hewa a hiki i ka meaola e ola ana, a e ia i ka hou ka mea, ua hoololiia ka nui ikehu i na nā'aʻaʻa.

Ma he ulia pakalaki likeʻole ma nukelea iauaeoia, a iloko o ke kaua me ka hoʻohana o nukelea mea kaua, me ka hoohuoi kumumea, e loli ai i ke kino, ka mea mea nui e noonoo i loko o ka luna '. Ma waho aʻeo i ke ahuwale physical hopena ma luna o kanaka nā palapala 'ole i kekahiʻano o ka electromagnetic a pāhawewe.
