Bayesian Analysis of Plutonium Bioassay Data at Los Alamos National Laboratory


doi: 10.1097/HP.0000000000001044

There is an error in the paper titled “Bayesian analysis of plutonium bioassay data at Los Alamos National Laboratory” (Poudel et al. 2018), which appeared in the December 2018 issue. The second to last paragraph of the Discussion section should read:

“The ID code uses the systemic model published in ICRP Publication 67 (ICRP 1993) to describe the biokinetics of plutonium once the material is introduced into the blood. It is important to note that the systemic model published in Leggett et al. (2005) represents an updated version of the ICRP 67 systemic model. The model was developed to reflect the discrepancies observed between the ICRP 67 model predictions and the more recent data, particularly bone and liver deposition fractions. The upcoming ICRP publication on occupational intakes of radionuclides also recommends the systemic model published in Leggett et al. (2005). A future version of the code can include this revised version of the systemic model.”

In addition, in the model description for the IEE model (in Table 3), the parameter st should be 4 × 10−3 d−1. Finally, the notation “e(50),” when followed by units Sv or rem, should be replaced by “E(50),” as the former is generally used to denote the committed effective dose coefficients (in Sv Bq−1).
