title: Discrepancies in committed effective dose equivalents calculated using U.S. Nuclear Regulatory Commission Regulatory Guide 8.34.
abstract: Calculations of Committed Effective Dose Equivalent (CEDE) due to inhalation using four of the five methods suggested in the United States Nuclear Regulatory Commission Regulatory Guide 8.34 (1992a) were performed to determine if any significant differences in the calculated value of the CEDE exist for typical power plant radionuclides. These four methods included dose conversion factors from the United States Environmental Protection Agency Federal Guidance Report No. 11 (Eckerman et al. 1988), Annual Limit on Intake, Derived Air Concentrations, and Weighted Committed Dose Equivalents from ICRP Publication 30 (1979). Of the 68 radionuclides included, 48 demonstrated significant differences of 20% or greater in the calculated CEDE values for the four methods used. The differences in calculated values for the CEDE can be explained by the varied use of the 10% Rule and by rounding of tabulated values for ALIs and DACs to one significant digit.
