a Mean annual dose from shipments of tantalum raw materials analyzed in this study.. b For perspective, doses to facility workers (who are not considered transport workers) were 0.49 and 0.31 mSv/y from slag and tantalite, respectively.. Doses to members of the public from the transport of these materials were found to be insignificant, that is, much less than 10 μSv/y.

On the trail of tantalum: tracking a conflict mineral

Tantalum occurs most frequently naturally in the form of tantalite ore which has the formula (Fe,Mn) [(Nb,Ta)O 3] 2. When the tantalum content predominates, the ore is referred to as tantalite. When more niobium than tantalum …
