Imitha, ngendlela yamaza okanye amasuntswana, luhlobo lwamandla oluhamba ukusuka kwenye indawo ukuya kwenye. Ukuvezwa kwimitha yinto eqhelekileyo kubomi bethu bemihla ngemihla, apho imithombo efana nelanga, ii-oven ze-microwave, kunye neerediyo zeemoto ziphakathi kwezona ziqatshelwayo kakhulu. Nangona uninzi lwale mitha ingabi yingozi kwimpilo yethu, ezinye iintlobo ziyenza loo nto. Ngokwesiqhelo, iidosi eziphantsi zemitha zithwala iingozi eziphantsi, kodwa iidosi eziphezulu zinokunxulunyaniswa neengozi ezandileyo. Ngokuxhomekeke kuhlobo oluthile lwemitha, amanyathelo ahlukeneyo okuzikhusela ayimfuneko ukuze sizikhusele thina kunye nokusingqongileyo kwimpembelelo yayo, konke oku ngelixa sisebenzisa amathuba ezicelo zayo ezininzi.
Iluncedo ngantoni imitha?
Impilo: Iinkqubo zonyango ezifana neendlela ezahlukeneyo zonyango lomhlaza kunye neendlela zokuxilonga ziye zabonakala ziluncedo ngenxa yokusetyenziswa kwemitha.
Amandla: Imitha isebenza njengendlela yokuvelisa umbane, kuquka nokusebenzisa amandla elanga kunye nenyukliya.
Indalo notshintsho lwemozulu: Imitha inamandla okusetyenziswa ekucoceni amanzi amdaka nasekuphuhliseni iintlobo zezityalo ezinokumelana nemiphumo yotshintsho lwemozulu.
Ishishini nesayensi: Ngokusebenzisa iindlela zenyukliya ezisekelwe kwimitha, izazinzulu ziyakwazi ukuhlalutya izinto zakudala okanye ukwenza izinto ezineempawu eziphuculweyo, ezifana nezo zisetyenziswa kwishishini leemoto.
Iintlobo zemitha
Imitha engayenzi i-ionizing
Imitha engayenzi i-ionizing ibhekisa kwimitha enamanqanaba aphantsi amandla angenawo amandla aneleyo okususa ii-electron kwiiathom okanye kwiimolekyuli, nokuba zikwizinto ezingaphiliyo okanye kwizinto eziphilayo. Nangona kunjalo, amandla ayo anokubangela ukuba iimolekyuli zingcangcazele, zivelise ubushushu. Oku kuboniswa ngumgaqo wokusebenza kwee-oven ze-microwave.
Uninzi lwabantu alukho emngciphekweni weengxaki zempilo ngenxa yemitha engangenisi i-ionizing. Nangona kunjalo, abantu abasoloko bechatshazelwa yimithombo ethile yemitha engangenisi i-ionizing banokufuna amanyathelo athile okuzikhusela kwimiphumo enokubakho efana nokuveliswa kobushushu.
Imitha ye-ionizing
I-ionizing radiation luhlobo lwe-radiation yamandla anjalo kangangokuba inokususa ii-electron kwiiathom okanye kwiimolekyuli, nto leyo ebangela utshintsho kwinqanaba le-athomu xa idibana nezinto eziquka izinto eziphilayo. Olu tshintsho ludla ngokubandakanya ukuveliswa kwee-ion (ii-athomu okanye iimolekyuli ezitshajiweyo ngombane) - yiyo loo nto igama elithi "ionizing" radiation.
Kwizinga eliphezulu, i-ionizing radiation inokwenzakalisa iiseli okanye amalungu omzimba womntu, kwaye kwiimeko ezinzima, inokukhokelela ekufeni. Nangona kunjalo, xa isetyenziswa ngokufanelekileyo kwaye ikhuselekile ngokufanelekileyo, olu hlobo lwe-radiation lubonelela ngeenzuzo ezininzi, kubandakanya ukusetyenziswa kwayo ekuveliseni amandla, kwiinkqubo zoshishino, uphando lwezenzululwazi, kunye nokuchongwa kunye nokunyangwa kwezifo ezahlukeneyo, kubandakanya nomhlaza.
