Decay Schemes for Radionuclides of Potential Importance in the Nuclear Fuel Cycle

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.
