He aha ka ana pāhawewe? ionizing pāhawewe

Ka manaʻo o "ka pāhawewe" ua paa i uhukiia i loko o kā mākou mau naau me ka loa io a me ka weliweli kŰia. Eia naʻe, kanaka hoʻomau e hana ia no kā lākou mau hana. He aha ia mea i loko o ka lanakila? He aha ka ana pāhawewe? Pehea ia e loli ai i ka meaola ola?

Ka pāhawewe a me ka Radioactivity

Lakina hua'ōlelo pāhawewe pāhawewe unuhi like "mālamalama", "kukui", a me ka manawa no ia mea, ho i ka ikehu ea puka kaʻina. Energy hoʻopulapula i loko o ka makahiki i loko o ka palapala o ke kahawai o (particles) a me ka ale.

Aia i acee? Iuo oeiia o ka pāhawewe - mea paha e thermal (welaʻula) malamalama, ultraviolet, ionizing. Ka hope o ka noho pilikia loa a me nā palapala, iʻaneʻi i nā Alpha, Hoʻokolohua, gamma, neutron a me ka X-kukuna. He heʻike makaʻole microscopic (particles) hiki o ionizing i ka waiwai.

Ka pāhawewe ke 'Aʻole i hele mai ma ona iho, ka mea, ua hanaʻia ma ka waiwai a me nä mea like me kekahi mau waiwai. Nā nuclei o nā'ātoma o kēia mau mea i ka poe i loko o lākou ka palaho hoʻomaka e pāhawewe hou ikehu. I ka hiki ana o ka waiwai a me ka poe kauwa na ionizing (radioactivity) pāhawewe kapa radioactivity.

radioactive kumu

Kue i ka manao i ka pāhawewe - ka mea, Aloha wale nukelea mana kanu a me ka hope, ka mea e e kaulana i loaʻa nō nāʻano o nā mea: i ka aoao maoli, a me kaʻimi hoʻopunipuni. Ka mua ka makana aneane mai'ō a'ō. I ka makahiki ka mea, hiki ke hoʻokuʻu akula hoku e like me ko kakou la.

Ma Honua, radioactivity i ka wai, ka lepo, one, akā, i ka pāhawewe mahele lāʻau i loko o keia hihia mea,ʻaʻole he nui. Kēia make i ka 5 a hiki i 25 anakahi iki roentgens no hora. Hiki i ka pāhawewe a paʻa Honua iho. O kona naʻau hoʻohui pū i ka ai iiiaanoaa o radioactive mea, e laʻa me, lanahu a me ka uranium. I kŰia mau mea i like nā pōhaku lepo.

ʻimi hoʻopunipuni pāhawewe kanaka loaa wale i loko o ka XX kenekulia. ua Man aʻo i ka hana ma luna o kāna mau 'ōlelo' ona lolelua e paka ikehu e hōʻeleu i ka neʻe o hoopiiia (particles). E like me ka hopena, ua kila pāhawewe kumu, nukelea mana a me ka nukelea mea kaua, na mea paahana, no kaʻike, a me ka sterilizing nā huahana.

He aha ka ana pāhawewe?

Ea puka pāhawewe ua pu e likeʻole keʻano o ka hanaʻana, akā naʻe, loaʻa nō kekahi mau huahelu i emi iho ka hana o ionizing paialewa a me ka maʻamau. Names o ka mea ua anaia mai ka manawa ma ka pāhawewe, e me nā inoa o nā kānakaʻepekema, ka poe hookolokolo aku la ia ia pinepine pili. No laila, ma laila becquerel, curie, pendants a me ka X-kukuna. No ka Pahuhopu auhau o ka pāhawewe ana waiwai o radioactive mea :

Ua ana i ka hopena o ka radioactivity ma non-ola'aʻaʻa like penei:

pāhawewe waiwai ma luna o ola meaola:

kanaka waiū

Ka pāhawewe ke pāhawewe ke hiki i irreparable liluwelo loli i loko o ke kino. Paheona (particles) - Ion penetrating i ola'aʻaʻa hiki wawahi i ka mea paʻa ma waena o nā lātoma. O ka holo ana, i ka hookoia hilinaʻi nui ma luna o ka pāhawewe mahele lāʻau loaa. Natural kāʻei kua pāhawewe mea i pilikia ai i ke ola, a me 'oe hiki ole pakele no ia.

Ka pāhawewe waiwai ma luna o kānaka ua kapaia irradiation. Ua hiki e somatic (ke kino) a me ka aaiaoe. Somatic pāhawewe waiwai i hoikeia ma ke ano o kekahi mau maʻi: hikoko, leukemias, kāna hana no nā nā loko. I ka papa kuhikuhiE hoike ana o ka pāhawewe maʻi o ka loli iki ana oolea.

Aaiaoe 'ole o ka pāhawewe i hoikeia mai ma ka' aʻe 'ana o fertilization kino a he aha ka mea i ke ola o ka hanauna e hiki mai. Kekahi o na hoikeana o ka aaiaoe hopena o mutations.

Na penetrating hiki o ka pāhawewe

Eia naʻe, kanaka a ua i ka manawa e imi mai i ka mea o ka ikaika o ka pāhawewe. He ulia pakalaki i mai ai i loko o Ukraine a me Iapana, i ka hopena ma luna o na ola o na mea he nui kanaka. Prior i Chernobyl a me Fukushima hapanui o ko ke ao nei, aole ia i manaʻo e pili ana i ka pāhaweweʻano papa hana o ka hana, a me ka simplest maluhia ana.

Ionizing pāhawewe mea huna paha i kekahi kahawai o photons, ka mea, he mau hoailona ia mea, kela mea keia mea o ka a i kona penetrating hiki. Ka nawaliwali hoonoho i, alpha kukuna a me (particles). Ke'ākeʻakeʻa mai a hiki i ka ili mea lahilahi kapa no ia. I ka pilikia e hiki mai ana i ka hui 'ana me nā maʻiʻaʻai a digestive'āpana.

Ke Hoʻokolohua (particles) e electrons, kā lākou mau 'ole' ana lahilahi aniani, laau mea. X-kukuna a me ka gamma-kukuna komo iloko mea a fabrics mea maikaʻi. Ka mea, ke paa i ke alakaʻi i kekahi papa, he mika manoanoa, a me kekahi mau na umi o ka mika o ka pōhaku puna. Neutron pāhawewe ia lŘlŘ ka wāʻimi hoʻopunipuni hana iloko o ka nukelea naoh.

E mālama iā ia, mai i lako i loaʻa ka hydrogen, beryllium, graphite, ka wai ua hoʻohana ', polyethylene mahuahua.

ka hopena

Ma ka palahalaha pono, pāhawewe - pāhawewe mea he kaʻina hana e hele mai ana mai kekahi kino. IeAUPIIe, IAa IO ua hoʻohana 'ia i kēia manawa ma ke ano ka mea, ua ionizing pāhawewe - kahawai kula haʻahaʻaa (particles) e hiki loli i nā mea a me nā meaola. Ke kanawai o ka pāhawewe hiki e okoa, ka mea a pau hilinaʻi nui ma luna o ka mahele lāʻau.

Me maoli pāhawewe mākou halawai me kela lā, no ka mea, mea a pau a puni mākou. Kona huina mea IeAUPIIe, IAa IO uuku. ʻimi hoʻopunipuni pāhawewe hiki e nui hou weliweli, a me ka hopena o ia seriously.
