The decay schemes for a few of the radionuclides of potential importance in routine releases from nuclear fuel cycle facilities may contain significant uncertainties with regard to applications of the decay data to radiation dosimetry. These radionuclides include 92Sr, 115Cd (44.6 day), 133Te (55.4 min), 141La, 142Ba, 166Ho (1200 yr), 229Th, and 245Cm. The sources of uncertainty in each decay scheme are discussed, and additional measurements are proposed.
