Production of cobalt-57 for industrial and medical
Abstract. Cobalt-57 (57Co) has emerged as a promising radionuclide and as an isotope for diagnostic and calibration sources. Herein, we report the production, chemical separation, and quality control of 57Co in an RFT-30 cyclotron facility. 57Co is produced via (p, 2p) nuclear reaction using an enriched 58Ni target material.

What are Cobalt Spinels?
As allochromatic gemstones, spinels get their color from trace elements. For years, gemologists thought the same iron-to-iron interaction that results in darker, greenish blue body colors in spinels also caused vivid blue hues. However, in 1984, scientists first identified cobalt as an additional coloring agent for highly saturated blue spinels ...
