Uranium and thorium in urine of United States residents: Reference range concentrations

  • 1. Centers for Disease Control and Prevention, Atlanta, GA (United States)

Description

The authors measured uranium and thorium in urine of 500 US residents to establish reference range concentrations using a magnetic-sector inductively coupled argon plasma mass spectrometer (ICP-MS). They found uranium at detectable concentrations in 96.6% of the urine specimens and thorium in 39.6% of the specimens. The 95th percentile concentration for uranium was 34.5 ng/L (parts per trillion); concentrations ranged up to 4,080 ng/L. Thorium had a 95th percentile concentration of 3.09 ng/L; concentrations ranged up to 7.7 ng/L
