A nazarin halittu sakamako na radiation a kan mutum

A nazarin halittu sakamako na radiation a kan mutum ta'allaka ne a ionization jiki nama Kwayoyin da bayyanar radiation cuta. A cuta ne zai dogara ne a kan da yawa dalilai: yankin ya shafa, da kashi na ionizing radiation, lokacin a lokacin da kashi samu.

ionizing radiation

Lokacin da high-makamashi barbashi ko photons wanda wuce ta cikin abu da suka samar da wata biyu a cikin hanyar caje barbashi, wanda ake kira ions. Saboda haka yana da hatsari ne ionizing radiation. A nazarin halittu sakamako na radiation yana da wani girma sakamako a kan rayuwa al'amarin. Rayuwa nama - suna Kwayoyin cewa an kullum ana updated, shi ne wani mashahurin tsari. Kuma ionizing radiation ne ninki biyu masa zafi.

Sashe na daga cikin radiation rauni dangantawa da inji raunuka na kwayoyin Tsarin kamar chromosomes. A part - da sunadarai matakai faruwa da 'yantar radicals. Tun da mutum ya 75% na ruwa, na farko radiation ne radiation mamaye ruwa Kwayoyin, kafa free radicals kamar OH, HO2, N. A cikin wadannan hadawan abu da iskar shaka dauki auku sarkar radicals daga wadannan sunadarai na gina jiki. Sa'an nan kuma akwai aikin canje-canje a cikin dokokin da nazarin halittu cell rayuwa.

Wadannan canje-canje faruwa a cikin Kwayoyin:

• rarraban inji lalace kuma suka ji rauni cell chromosomal na'ura;
• An katange aiwatar da sabuntawa da kuma bambance na sel.
• An katange aiwatar da yaduwa da kuma nama farfadowa.

M radiation ciwo

A sosai high kashi na ionizing radiation (mafi girma daga 600 Rad) take kaiwa zuwa m halakar da mutum (idan ba za'ayi wani magani). A wani kashi na 400-600 Rad kashe game da 50% na mutanen da. Ya fara m radiation cuta, a lokacin da ya rushe, kuma ya mutu hematopoietic tsarin (ja bargo) da kuma daina aiki tsaro tsarin.

A makon farko na m radiation ciwo ne asymptomatic - abin da ake kira latent lokaci da cutar. Sa'an nan ya zo da wani rashin lafiya, kasa da na rigakafi da tsarin, an fara ƙara duk kullum cututtuka da kuma sabon cututtuka. By game da huɗu mako na tasowa anemia, da jini daina ninka ƙãra hadarin zub da jini.

A halin yanzu matakin na magani ba ka damar ceton mutanen da suka karbi wani kashi na ionizing radiation zuwa 1000 Rad. A baya can, da nazarin halittu da sakamakon radiation a wani adadin ba za mu bi. Radiation cuta - wannan shi ne wani matsananci mataki na lalacewa. Karami allurai zai iya sa cutar sankarar bargo da kuma daban-daban m siffofin maruran.

Sources da iri radiation daukan hotuna

A mutum na iya samun wani hatsari kashi na radiation daga radiation wucewa girgije ko daga gurbata saman gine-gine, gine-ginen da ƙasar. Wannan ake kira waje radiation. Ciki daukan hotuna na faruwa a lokacin da wani mutum inhales kamuwa da aerosol (inhalation Hazard) ko jan gurbata abinci da ruwa. Rediyoaktif abu iya samun shiga cikin fata da kuma tufafi. Irin wannan daukan hotuna da aka kira lamba.

A nazarin halittu sakamako na radiation iya haifar da wadannan effects:

• Somatic stochastic. Su ne wuya a gane da kuma maiyuwa bazai bayyana ba shekaru da dama.
• Somatic. Ana rinjayar kawai mutum daukan hotuna a zuriyarsu ba ya canzawa.
• Kwayoyin. Keta jima'i cell Tsarin fallasa mutane da shafi zuriya, wanda ya bayyana tare da nakasar nakasar da kuma maye gurbi.

A mataki na daukan hotuna dogara ba kawai a kan kashi amma kuma a kan lokaci na daukan hotuna zuwa radiation. A kashi na 300 Rad, sakamakon da 'yan watanni, da cuta ba kai, da kuma a lokaci daya zai iya kai ga tsanani sakamakon. M radiation cuta na iya faruwa a lokacin da karbar guda kashi na 100 rads.
