<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Umlando: UKamen wazalwa ngo-August 27, 1913, eToronto, eyindodana yabafuduki abangamaJuda baseRussia. Wakhulela eChicago. Wathola iziqu ze-bachelors degree ku-chemistry e-University of Chicago ngo-1933 futhi wathola i-PhD ku-physical chemistry eyunivesithi efanayo ngo-1936. Ngemva kwalokho wafuna isikhundla sokucwaninga ngamakhemikhali nange-nuclear physics ngaphansi kuka-Ernest Lawrence elabhorethri yemisebe eBerkeley, lapho asebenza khona ngaphandle kokukhokhelwa izinyanga eziyisithupha waze waqashwa ukuba engamele ukulungiswa nokusakazwa kwemikhiqizo ye-cyclotron. Nakuba i - carbon - 14 yayikwaziwa ngaphambili, ukutholakala kokuhlanganiswa kwe - carbon - 14 kwenzeka eBerkeley lapho uKamen noRuben beqhumisa i - graphite e - cyclotron benethemba lokukhiqiza i - radioactive isotope ye - carbon engasetshenziswa njengento yokulandelela ekucwaningeni ukusabela kwamakhemikhali ku - photosynthesis. Ukuhlola kwabo kwaphumela ekukhiqizweni kwekhabhoni - 14. Umbuzo: UKamen wathola nini iziqu zakhe zobudokotela?  <response>: Ngo-1936
