The median urine concentration of uranium for the people tested in Churchill County was 0.02 μg/L compared with 0.006 μg/L for people reported in the Second National Exposure Report. The U.S. Nuclear Regulatory Commissions action level to protect people exposed to uranium at work is a urine uranium level of 15 μg/L. In one study of people who drank well water with high natural uranium concentrations, the median urinary concentration was 78 μg/L without effects on their kidney function. We are not aware of any studies that reported health problems in people with urine levels of uranium in the range found in people in Churchill County.
