Correction to Calculating Radiation Exposures during Use of ¹⁴C-Labeled Nutrients, Food Components, and Biopharmaceuticals To Quantify Metabolic Behavior in Humans

The final sentence under the heading Sample Collections (in the Materials and Methods section) should read as follows: When 100 nCi of ¹⁴C was dosed to the 70 kg human subject, collected samples had 0.0014 nCi of ¹⁴C/g, a level below the U.S. Code of Federal Regulations, Title 10, Section 20.2005, 1991 (cutoff for nonradioactive waste from ¹⁴C animal studies, ≤50 nCi/g or 1 μCi/year).
