TRITIY

TRITIY (lotini tritium, az yunoni tritos –seyum), tritiy ( yo 3N), gidrogeni vaznin, izotopi beta-radioaktivii girdrogen , ki adadi masaash 3 ast. Soli 1934 olimoni anglis E. Rezerford, M.L. Olifant va P. Khartek kashf kardaand. Yadroi atomi tritiy az yak proton va 2 neytron iborat ast. Tritiy faol buda, davrai nimkohishiash T ½= 12, 26 sol meboshad. Dar tabiat tritiy ba miqdori kam az tasiri neytronhoi nurhoi kayhoni ba atomi nitrogen (147N+n=31 T+126C) hosil meshavad. Miqdori tritiy dar obhoi tabii khele kam buda, ba hisobi miyona ba har 10 18 atomi 1N 1 atom tritiy rost meoyad. Dar sanoat tritiyro dar reaktorhoi nurboronkunii litiy hosil mekunand:
63 Li+n=31T+42 He
Tritiyro hamchun muhimtarin juzi tarkibi sintezi termoyadroi, chun suzishvori (dar bombahoi termoyadroi), inchunin dar tadqiqothooi khimiyavi, biologi va gidrologi vase istifoda mebarad.
