Alpha spectrometry and secondary ion mass spectrometry of electrodeposited uranium films
Electrodeposited natural uranium films prepared by electrodeposition from solution of uranyl nitrate UO 2 (NO 3 ) 2 ·6H 2 O on stainless steel discs in electrodeposition cell. Solutions of NaHSO 4 , and Na 2 SO 4 and electric current from 0.50 up to 0.75 A were used in this study. Recalculated weigh...

and electric current from 0.50 up to 0.75 A were used in this study. Recalculated weights and surface’s weights of

U from the alpha activities and secondary ion mass spectrometry (SIMS) intensities resulted in a linear regression. A dependency between of
238
U surface’s weights recalculated from alpha activities and signal intensity of
238
U in SIMS was investigated in order to determine a potential of SIMS in quantitative analysis of surface samples containing uranium. In the SIMS spectra of electrodeposited uranium films we found that upper layer consist not only from isotopes of uranium (ions
