Absorbed dose coefficients (mGy/MBq) with contribution from alpha, beta and gamma radiation to the total absorbed dose, after simulated injection of ²²³Ra, in comparison to the modelling study of Lassmann and Nosske [20] and the clinical studies of Chittenden et al. [10] and Yoshida et al. [8]. Values of Yoshida et al. refer to total absorbed dose coefficients
