dc.description.abstractThis study pertains to the practice of multibadging currently being utilized by the commercial nuclear power industry in order to estimate effective dose equivalent from non-uniform photon radiation fields. Actual multibadging data acquired voluntarily from various nuclear power plants throughout the United States were used. The data were analyzed with respect to the current practice of assigning the highest whole body multibadging dosimeter reading as the dose of record pursuant to 10 CFR (Code of Federal Regulations) Part 20 with the results obtained from using recommended methodologies from the scientific community. These recommendations are discussed in detail in NCRP Report 122 (1995), ANSI 13.41 (1997), and EPRI Reports TR-101909 Volumes 1 and 2. This comparison of methodologies for estimating effective dose equivalent indicated that the current practice of using many dosimeters placed on various portions of the whole body could be replaced by using one, or at most two, dosimeters. The analyzed multibadging data demonstrate that the use of one dosimeter placed either on the chest or back of a radiation worker (depending on which surface of the torso receives the highest exposure) yields estimates of effective dose equivalent within 10% of the current conservative approach.en
