IONIZATION-RATE AND PHOTON PULSE-RATE DECAY OF FISSION PRODUCTS FROM THE SLOW-NEUTRON FISSION OF U$sup 23$$sup 5$

Technical Report ·
OSTI ID:4297036
Computations giving the theoretical ionization rate and response of the AN/PDR-39(TID) radiac at 3 feet above an infinite plane uniformly contaminated with fission products from 10/sup 4/ fissions of U/sup 235/ per sq ft. are presented as a function of time after fission. The response of the USNRDL 4 pi ionization chamber and the photon pulse rate for the fission products are also presented as a function of time after fission. Disintegration-rate multipliers for each fission product nuclide per d/s of the nuclide are given; the multipliers were used to obtain the contribution of each fission product nuclide to the gross response. The theoretical ionization rate decay curve was integrated to obtain the gamma dose from the fission product mixture for various periods of time after fission. (auth)
