OSTI ID:4322283
Photon energy radiation rates and photon emission rates from the fission products produced by slow-neutron bombardment of U/sup 235/ are computed, using nuclear decay scheme data and the results of new computations for the gross activity in terms of disintegration rate. The computed rates were used to determine, as a function of time after fission. the mean photon energy per disintegration and the number of beta rays per photon. Curves showing photon energy radiation rates, photon emission rates, and beta rates for a time range of about 46 min to about 300 years after fission are presented. The relative percent contributions of the fission product elements to the photon energy radiation rate for the same time range are listed and plotted. A comparison is made of activity and the computed photon energy radiation rates for 1 hr to 3 years after fission. A comparison is also made of the number of fissions and neutron capture/fission ratio for neutron bombarded samples of U/sup 235/ and of U/sup 235/ + U/sup 238/ as determined by the decay curve amalyses and by radiochemical analyses. The computed decay curves for 10/sup 4/ fissions from slow-neutron fission of U/sup 235/ using the USNRDL 4-pi Ionization Chamber is presented. (auth)
