Kuyini ukubola kwemisebe?
Context:Ukubola kwe-radioactive (okwaziwa nangokuthi ukubola kwe-nuclear, i-radioactivity, ukubola kwe-radioactive, noma ukubola kwe-nuclear) inqubo lapho i-nucleus ye-athomu engazinzile ilahlekelwa amandla ngemisebe. Izinto eziqukethe izinhlayiya ezingazinzile zibhekwa njengezikhipha imisebe. Izinhlobo ezintathu ezivame kakhulu zokubola yi-alpha decay (α-decay), ukubola kwe-beta (β-decay), nokubola kwe-gamma (γ-decay), konke okubandakanya ukukhipha inhlayiya eyodwa noma ngaphezulu. Amandla abuthakathaka ayindlela ebangela ukubola kwe - beta, kuyilapho amanye amabili elawulwa amandla kagesi kanye namandla enuzi. Uhlobo lwesine lokuwohloka okuvamile ukubanjwa kwama - electron, lapho i - nucleus engazinzile ithumba i - electron yangaphakathi kwenye yezembozo zama - electron. Ukulahleka kwalelo electron kusuka egobolondweni kuphumela ekushayweni kwama-electron kwehlela phansi kulelo gobolondo elingaphansi okuholela ekukhishweni kwemisebe ye-X ehlukile evela ekuguqukeni. Isibonelo esivamile yi-iodine-125 esetshenziswa kakhulu kwezokwelapha.
Ukubola kwemisebe kuyinkqubo lapho i-nucleus ye-athomu engazinzile ilahlekelwa amandla ngenxa yemisebe. Yaziwa nangamagama anjengokuthi ukubola kwe-nuclear, i-radioactivity, ukubola kwe-radioactive, noma ukubola kwe-nuclear.
