Imitha yokutya

imitha

La imitha yokutya, ngokusemthethweni ibizwa ngokuba yi-ionization, ibandakanya ukubeka ukutya kwimitha ye-ionizing, imitha ye-gamma kunye ne-X-ray. Le nkqubo, eyaqanjwa ngoo-40 ngoososayensi baseFrance, kwiimfuno zotshintshiselwano lwamazwe aphesheya, ivumela ukutya kungangcoliswa, kucinezela ezincinci kunye nezinambuzane, ukunciphisa isantya sokuvuthwa, ukuthintela ukuntshula kunye nokugcina ukutya ngcono. Ikwavumela ukuthuthwa okungcono kwimigama emide, kunye nokugcinwa kwexesha elide.

Izibonelelo zemitha yokutya

La imitha yokutya ayenzi ukutya okune-radioactive. Akufanele iphazanyiswe nongcoliseko lwe-radioactive. Ngokwesiqhelo ibonakaliswa njengengabalulekanga kunezinye iindlela zokugcina imveliso, obu buchwephesha benza ukuba kuthintelwe ukusetyenziswa kweemveliso zamachiza.

Kulula nokuyisebenzisa kune kubanda, kwaye inokusetyenziswa kuzo zonke iimveliso, kubandakanya iimveliso ezintsha, ngokuchaseneyo nonyango olusekwe kubushushu.

Abaxhasi be imitha yokutya Bayibeka njengesisombululo esingummangaliso ngokuchasene nezifo ezibangelwa kukutya. Ngelishwa, uninzi lwezifundo zesayensi zibonisa umda kunye nomngcipheko kwimpilo yemitha ngokunjalo.

Umngcipheko wemitha

Eminye imibutho ekukhuseleni abathengi kunye nokusingqongileyo kugxininisa ukuhlupheka kwexabiso lezondlo leevithamini ezifumaneka ekutyeni. Nangona imitha yelanga yanele ukubulala izinto eziphakamileyo, ayizisusi iityhefu ezikhutshwe ziintsholongwane kunye nefungi. Nangona kunjalo, inokutshabalalisa iivithamini kwaye ibangele ukwenziwa kwezinto ezisandula ukwenziwa okanye ii-radicals zasimahla eziyingozi kwimpilo yokutya.

Abanye ibhaktheriya Ziluncedo kakhulu kuba zenza ngokuvela kokutya kwaye ke zivumela abathengi ukuba bafumane ukutya okukrokrisayo. Ukutya okunemitha kubonakala kunempilo, kodwa akusoloko kusempilweni. Ngesi sizathu, imitha ingasetyenziselwa ukufihla iimveliso ezindala kakhulu kwaye akufuneki zisetyenziswe kubathengi, kwaye ke zinokufakwa endaweni elungileyo. izenzo ucoceko okanye yokurisayikilisha kwemveliso efikelela kumhla wokuphelelwa kwayo.

Los ukutya ionized zinokuqulatha izinto ezikrokrelwa ukuba zingumhlaza. Kweli nqanaba, izilwanyana zaselebhu ezityiswa ukutya okukhanyiselwe ixesha elide zithwaxwa zizifo zemfuza, iingxaki zokuzala, ukukhubazeka kunye ukubhubha kwangethuba.

Umngcipheko kwindalo esingqongileyo

Ngokwembono yendalo esingqongileyo, sinokuchaza ingozi enxulumene nokusebenza kwezixhobo kunye nokuthuthwa kwezixhobo zenyukliya. Ukongeza, obu buchule buthintela imveliso yeemveliso kunye neendlela zokuhambisa apho uthutho, umthombo we ngco liseko, ayisengxaki ekulondolozweni kokutya.

Oku kuneziphumo, kuba i radiationNgokwandisa ixesha lokugcinwa kokutya, ubeka emngciphekweni wokunyusa ukuhanjiswa kwemveliso yezolimo apho imigaqo okusingqongileyo kwaye iingxaki zentlalo zinokuba lusizi kwizityalo ezinokulinywa ekuhlaleni.


Umxholo wenqaku uyabambelela kwimigaqo yethu imigaqo yokuziphatha yokuhlela. Ukuxela impazamo cofa apha.
