(1985) based on ORNL reports (Killough et al., 1978a; Dunning et al., 1979) and often used in dose reconstructions for atomic veterans; values are based on dosimetric and biokinetic models in ICRP Publication 30 (ICRP, 1979a). Second entry, in parentheses, is value for AMAD of 1 μm currently recommended for adult workers by ICRP (2002). All values apply to radionuclides in oxide form (Eckerman et al., 1988).
