- ABSTRACT Analysis of 0/U ratio in unirradiated and irradiated uranium oxide were carried out by using polarography and spectrophotometry method. Some samples of uranium oxide (UO7+ x) were irradiated in reaktor Kartini having neutron flux of 5 10I°n cm 2 s for 314, 2, 3 and 4 hours, and cooled for. 3 months. Irradiated samples UO2+ x then were dissolved in mixture of sulfuric, boric, fluoric acid and ammonium fluoride and heated for 25 minutes. The solution obtained were 'analyzed with polarography from 0 V nm - 0.241 V and with spectrophotometry method at 420 nm and 665 nm for U(VI) and U(IV) respectively. It was found that the difference result between polarography and spectrophotometry method was significant from statistically point of view.
