Abstract Se in Ni and Co concentration in concentrates obtained from the nickel industry has to be determined for quality control requirements in their commercialization. Analysis of Se at minor and trace levels is relatively complicated and destructive procedures are frequently required. In this work the determination of Se by epithemal neutron activation analysis (ENAA) in 17 samples from Cuban nickel industry was investigated. Application of ENAA allowed nondestructive determination of Se concentration down to ppm level in spite of the presence of high Co, Fe, Ni and Cr contents in the samples. For attenuation of the thermal neutron flux a Cd filter was utilized.
