Yankovich et al. (2010) presents a compilation of wholebody:tissue concentration ratios for a range of different radionuclides and terrestrial and aquatic animals. Look-up tables adapted from Yankovich et al. can be viewed from the links below.

To use the ratios a tissue-specific activity concentrations should be multiplied by the appropriate whole-body:tissue concentration ratio.

Given the uncertainty around the collated values Yankovich et al. recommended that ratios of between 0.75 and 1.5 should not be applied and that a value of 1.0 should be assumed instead. In the tables which can be accessed below and values between 0.75 and 1.5 have been replaced with a value of 1.0.
