In the paper by Williamson and Dauer entitled, “Activity Thresholds for Patient Instruction and Release for Positron Emission Tomography Radionuclides,” which appeared in the March 2014 issue, there is an error on page 348. The first word in the paragraph that begins with “Tellurium-201” should be “Thallium-201.”
