Equivalent whole-body dose estimation after simulated in vitro partial-body exposure to a 3-Gy dose. Different proportions of 3-Gy irradiated blood were mixed with unirradiated blood at various fractions. Radiation doses were estimated to the fractions along with lower and upper confidence limits (LCL and UCL) based on previously published (Wilkins et al. 2008) coefficients of AFRRI’s calibration curve using DoseEstimate software (v.2, Ainsbury and Lloyd, 2009). Determination of LCL and UCL was based on exact Poisson error on yield. Dispersion index and u values were also calculated using the DoseEstimate software (v.2).
