In accordance with the international safety requirements, particularly those established by the International Atomic Energy Agency (IAEA) in the General Safety Requirements (GSR part 3), materials containing naturally occurring radionuclides from the uranium and thorium decay series with an activity concentration of 1 Bq/g are generally considered to fall within the scope of regulatory control. This work was devoted to the analysis of variability of specific activity of cobalt hydroxides from four companies in the city of Kolwezi, particulary those reputed to have deposits slightly enriched in radioactive materials. Nearly 150 samples were collected to carry out this study, and the specific activities were calculated after analysis using an X-ray fluorescence spectrometer. The activity concentration determined in the present study remains below this reference level. Nevertheless, the findings warrant a documented radiological assessment conducted under a graded approach to radiation protection. Consistent with the fundamental principles of radiation protection recommended by the IAEA namely justification, optimization and dose limitation- the measured radiological levels indicate that handling, storage, and transport operation may be performed under normal operating conditions. This conclusion is contigent upon the implementation of good industrial practices and the establishment of periodic radiological monitoring to ensure continued compliance with regulatory standards.
