New paper shows acceptable radiation exposure from beneficial use of alumina waste

ToxStrategies scientist Dr. Bill Rish is a co-author of a new article that demonstrates acceptably low doses of naturally occurring radiation (NORM) when using the waste from alumina production (APR, or alumina production residue) in producing and using cement. Putting APR to this beneficial use, instead of storing it indefinitely, has raised concerns about workers involved in cement production or use, or members of the public, being exposed to radiation. The findings of Dr. Rish and colleagues, however, demonstrate that workers or the public being exposed to radiation over the life cycle of APR reuse will not receive doses in excess of any current risk-based standards. The article is published in the Journal of Air & Waste Management Association.
