Ke liluwelo hopena o ka pāhawewe ma luna o kanaka

Ke liluwelo hopena o ka pāhawewe ma luna o kanaka ke moe ia ma kona ionization kino'aʻaʻa keena a me ka nānā aku i ka pāhawewe maʻi. Ka maʻi mea e hilinaʻi ma luna o na mea he nui aʻe: ka wahi iʻa, ka mahele lāʻau o ionizing pāhawewe, i ka manawa i i ka mahele lāʻau loaa.

ionizing pāhawewe

I ka kiʻekiʻe-ikehu (particles) a me photons i kekahi, ma ka waiwai ka mea, nāna i hana i ka paʻa i loko o kona ala ana i hoopiiia (particles), i ka poe i kaheaia Ion. No ia mea, ka mea, ua pilikia loa ua ionizing pāhawewe. Ke liluwelo hopena o ka pāhawewe i ka mea i oi aku ia ma luna o ola mea. E noho nei'aʻaʻa - e aeee i mea mau i ka moʻolelo, ia mea he hōʻeuʻeu kaʻina. A ionizing pāhawewe meaʻale huli ola no ia.

Part o ka ino pāhawewe pili me ÿano lesions o hakakino hale e like me chromosomes. Ma hapa - i ka Nine Inch keʻano o ka hanaʻana e lawe me ka hookuuia radicals wahi. Mai ke kanaka 75% o ka wai, ka mua pāhawewe ka pāhawewe Komo 'o ia i ka wai keena, ho okumu i noa radicals e like me OH, HO2, N. Ma ka kēia'okesaside naoh ia lŘlŘ lei radicals o kēia mau kumuʻiʻo nā lātoma. A laila, loaʻa nō ooieoeiiaeuiuo loli i nā kānāwai o ke liluwelo aeea ola.

ʻO kēia nā loli ana i loko o na keena:

• anaʻano papa hana ua poino a me ka poino aeea chromosomal i hoʻomākaukauʻia;
• wahi i ke kaʻina hana o ka hou a me ka differentiation o keena;
• wahi i ke kaʻina hana o ka hoʻonuiʻana a me ka'aʻaʻa e noho.

Ka hapa nui o ka liluwelo hopena o ka pāhawewe hopena ma luna o ka mau moʻolelo iwi ka lolo, spleen, gonads, etc.

Huʻi pāhawewe maʻi pale

A mahele lāʻau kiʻekiʻe loa o ionizing pāhawewe (oi aku ma mua o 600 rad) hiki aku ai i ka kokololio ka make ana o ke kanaka (ina i lawe mai i kekahi lapaau). Ma kekahi mahele lāʻau o 400-600 rad pepehi ma kahi o 50% o ke kanaka. Ua hoʻomaka huʻi pāhawewe maʻi, i ka wā i collapses a make hematopoietic'ōnaehana (ula iwi lolo) a me ka mahana e hana ana i mea e malu ai nenoaiu.

I ka hebedoma mua o ka huʻi pāhawewe maʻi pale i asymptomatic - ka ai-kapaia latent wā o ka maʻi. Alaila, hele mai i ka hālāwai hope, ke aloha i ka'ōnaehana paleʻea'ōnaehana, e hoomaka ana i ka escalate a pau maʻi maʻi a me ka hou nā mea palahēhē. E pili ana i ka hebedoma ha o ka ulu anaemia, i ke koko pohaku i pa, a mahuahua nui kamepiula o ke kahe ana ke koko.

Ka papa nui o ka lapaau e leie aku oe e hoola i na kanaka, ka poe i loaa i ka mahele lāʻau o ionizing pāhawewe i ka 1000 rad. Mamua, i ka liluwelo ole o ka pāhawewe i loko o ka nui ole i ka pono. Ka pāhawewe maʻi - keia mea he lōʻihi loa o ke poho. Liʻiliʻi nā māhele hiki i leukemia a me kela malignant hikoko.

Sources a me ka ano o ka pāhawewe waiū

A kanaka ke loaa ia ia i kekahi mea pepehi weliweli mahele lāʻau o ka pāhawewe mai ka pāhawewe hele ao ole mai ka ua hoʻohaumiaʻia surfaces o nā hale, kahi Ű a me ka aina. Keia ua kapaia mawaho pāhawewe. Kūloko waiū ia lŘlŘ ka wā i kekahi kanaka inhales iho mailoko o aerosol (inhalation p ÷ ino) ole i pau ai ua hoʻohaumiaʻia ai a me ka wai. Radioactive mea e komo i loko o kaʻili a me ka aahu. Oia waiū ua kapaia o ka leo.

Ke liluwelo hopena o ka pāhawewe hiki i ka hahai ole:

• Somatic stochastic. Ka mea, ua paʻakikī e huai ae, a i ole ikea no ka makahiki.
• Somatic. Ka mea, e loli wale na kanaka waiū ma ka mamo ua i loli.
• Aaiaoe. Hoohaumia i moe aeea hale i hooleiiaʻi mawaho kanaka i ka hua, i akaka ia me congenital deformities a me mutations i aloha ia.

Ke degere o ka waiū hilinaʻi nui ole wale ma luna o ka mahele lāʻau akā, i ma ka manawa o ka waiū i ka pāhawewe. Ka mahele lāʻau o ka 300 rad, kūpono ai i loko o kekahi mau mahina, i ka maʻi, aole ia i alakaʻi, a ma kekahi manawa ke alakai i ka hoʻoponopono ulia pōpilikia 'hopena. ka wā e loaa ana he hookahi mahele lāʻau o ka 100 rads huʻi pāhawewe maʻi hiki ke kānāwai.
