Radiation yangasemva

Le yangasemva radiation - na imitha ka radioactive imvelaphi, zikhoyo kwihlabathi womntu-nezendalo imithombo. Kufuneka kuqatshelwe ukuba umntu ochaphazelekayo umphelo. Akwenzeki ukuba kukuphepha ngokupheleleyo kwimitha. On Earth, kwavela ubomi kwaye ziphuhliswe phantsi zokukhanya oluqhubekayo. radiation Imvelaphi sinezi zixhobo zilandelayo: imitha evela atom ngumntu, oko kukuthi, ukususela endodeni; imisebe atom abakulo emoyeni, ezisemhlabeni eqweqweni kunye nezinye izinto yokusingqongileyo; Space.

Le zokukhanya yi bangaphakathi kunye nabangaphandle. Le yokugqibela ibangwa imithombo ukuba ibekwe ngaphandle komzimba (umhlaba kunye nendawo). Atom ukuba ngqo emzimbeni womntu, ukungasithakali lwangaphakathi luyenziwa. Isiqalo radiation kule ndawo lulinganiselwa kwi exposure idosi.

Ngenxa nendawo radiation dose ngomnyaka wamashumi amabini anesihlanu millirem ngamnye ngonyaka ofumana uninzi yabemi iplanethi yethu. Malunga umlinganiselo ofanayo abantu kwimithombo yendalo ukuba zangaphandle. Zi- ithamo lwangaphakathi malunga namashumi mathathu anantlanu millirem ngonyaka nge-avareji. Ngoko ke, inani lilonke sesichengeni kwabantu lwangaphakathi nolwangaphandle, ethatyathwe kwimithombo yendalo, kukuthi, ngokomlinganiselo, malunga namakhulu amabini mrem iinyanga ezilishumi elinambini.

imithombo ezongezelelweyo radiation na ngenxa yempembelelo yomntu okusingqongileyo singqongwe oko, kuquka atom zendalo ukuba kukuninzi ngokwaneleyo acatshulwe kwi-izibilini eMhlabeni okubonakalayo ukuba izinto zokwakha, izichumisi, ioli, igesi kwakunye namalahle, njalo-njalo.

Umlinganiselo lo radiation yangasemva kubaluleke kakhulu kwaye ufuna inkqubo. Kulo mzekelo, imimandla ukuba kuyingozi ukuhlala. uviwo radiology kuyimfuneko kubo bonke abo ndinyamekele impilo yabo. Xa ukulinganisa radiation yangasemva bahlole zangaphandle gamma-radiation emhlabeni; esweni radiation of izinto ukutya ekrwada kunye ezityiwayo; ulawulo iisampuli ezikhethiweyo umphutha zoshishino; iinkuni, isinyithi kunye neemveliso zayo, izinto zokwakha; sokulawula ukuphuza kunye namanzi mveliso.

Ionizing radiation kuthiwa, ngqo okanye ngokungathanga ngqo abangela ukuyilwa ion kakubi yaye ngokuqinisekileyo wamwisela (ionization-bume ezingqongileyo).

Ebudeni bexesha komhlaba iplanethi ionizing radiation asasazwa emajukujukwini. izinto radioactive langoku emhlabeni uqweqwe, kunye reyi yesiqalo ukuba iziphathi yendalo radiation ionizing.

Imithombo ionizing radiation zizixhobo zonxibelelwano ombane aphezulu ebizwayo-yamasuntswana accelerators, izinto ezineeathom ezilinganayo enziweyo radioactive, iziphenduli zenyukliya, oomatshini x-reyi, njl Ionizing radiation zombini iisoyi kunye zendalo, usenokuba corpuscular kwaye kagesi (umyinge okanye photon).

Bonke babe namandla eliphezulu kwaye kunokubangela utshintsho izakhiwo ngokobugcisa iiseli, oko kunokukhokelela ekufeni kwabo.

Le yangasemva radiation yovavanyo lomngcipheko oluchanileyo ngenxa utshintsho Kucacile ukuba Azifumaneki yobhaliso njongo, ngeedosi ezincinane ionizing radiation akubangeli. Ngokupheleleyo ngempembelelo radiation ngemvelaphi emzimbeni womntu alifumaneki. Ngokuqinisekileyo ayikwazi iphephile nayiphi na imali, kuquka leyo eyenziwe radiation yangasemva. Noko ke, kwakungenakwenzeka ukuba ukubona isiphumo encinane kakhulu (ubungozi) xa amathamo eliphantsi.
