Radium Concentration Factors and Their Use in Health and Environmental Risk Assessment
Produced waters discharged to coastal and offshore waters can contain high levels of radium (Snavely, 1989). Radium is known to be taken up by aquatic animals, and tends to accumulate in bone, shell and exoskeleton. The biological uptake of radium by aquatic animals is of concern because of the potential for: (1) dose to aquatic animals from accumulated radium and the effects on individual animals, populations and ecosystems; and (2) increased cancer risk to people from ingestion of radium in food.
