[Data for the assessment of maximum allowable concentration of dust in the air of work zone during production of permanent magnets based on samarium and cobalt].

The hygienic studies revealed that one of the most unfavourable factors in permanent magnet production is presented by the composite dust of cobalt and samarium. The toxico-hygienic assessment of the composite determined its MAC in the working zone air at the level 0.05 mg/m3 (as to cobalt).
