  Purpose: Chromosomal dicentrics and translocations are commonly employed as
biomarkers to estimate radiation doses. The main goal of this article is to
perform a comparative analysis of yields of both types of aberrations. The
objective is to determine if there are relevant distinctions between both
yields, allowing for a comprehensive assessment of their respective suitability
and accuracy in the estimation of radiation doses.
  Materials and Methods: The analysis involved data from a partial-radiation
simulation study with the calibration data obtained through two scoring
methods: conventional and PAINT modified. Subsequently, a Bayesian bivariate
zero-inflated Poisson model was employed to compare the posterior marginal
density of the mean of dicentrics and translocations and assess the differences
between them.
  Results: When employing the conventional method of scoring, the findings
indicate that there is no notable disparity between the yield of observed
translocations and dicentrics. However, when utilizing the PAINT modified
method, a notable discrepancy is observed for higher doses, indicating a
relevant difference in the mean number of the two types aberrations.
  Conclusions: The choice of scoring method significantly influences the
analysis of radiation-induced aberrations, especially when distinguishing
between complex and simple chromosomal formations. Further research and
analysis are necessary to gain a deeper understanding of the factors and
mechanisms impacting the formation of dicentrics and translocations.
