Fig. 1From: Correction to: Quantitative SPECT/CT imaging of lead-212: a phantom studyDecay scheme of 212Pb. The mean alpha and beta energies are included. The relevant photons emitted and their energies are added to the transition. Photons with emission probabilities smaller than 1% per 212Pb decay or with energies below 70Â keV are not included. The data are taken from ICRP 107 [2]Back to article page
