S>The disintegration rates and photon emission rates were calculated for products of U/sup 235/ thermal neutron fission at the following periods after fission: 1, 3, 7, 14, 30, 50, 100, 200 days and 1, 1.5, 2, 3, 5, 10 years. Information on total chain yields was largely referred to Kateoff (1958). Decay schemes were from Strominger, Hollander, and Seaborg (1958). The distnibution of independent yields was neglected. The photons were classified into nine energy groups, covering the range 0.0 to 1.6 Mev, which correspond to the photopeaks in Nal(Tl) scintillation spectra. The total disintegration rates and the total photon emission rates were calculated as functions of time after fission. All the results were tabulated and compared with other published calculations.
