Table 2 The fraction between rudimentary self-irradiation S-values (calculated by assuming an absorbed fraction equal to 1 and the total energy emission per decay) and model-based self-irradiation S-values from either a kidney model (OLINDA version 2.1) or the bone marrow model used in this study [22]. A fraction differing from 1 emphasizes the complexity of the dosimetry model compared to the rudimentary approach
