Biota Dose Assessment at LANL for 2012

“…For example, cesium bioaccumulates in locations that are deficient in potassium, and strontium or radium bio-accumulate in locations that are deficient in calcium. In contrast, the LANL environment is rich in potassium and calcium (McNaughton 2008(McNaughton , 2013 Cesium and strontium have been studied in the LANL environment (Salazar 2006) though radium has not.…”

“…Strontium is also chemically similar to calcium, and strontium is also absorbed when calcium concentrations are low. This possibility was studied and reported in McNaughton et al 2013 andSalazar 2006, with the conclusion that the plant-to-soil concentration ratio for strontium is approximately unity.…”
