BETA DOSE RATES FROM NEUTRON-IRRADIATED URANIUM-235 CARBIDE PARTICLES,

Abstract

Small highly radioactive particles could be injected into the biosphere from the re-entry and burnup of a nuclear propulsion reactor. This would constitute a potential radiological hazard to man. The work reported is the experimental measurement of beta dose rates from fission products contained in pyrolytic-carbon-coated uranium-235 carbide beads of core diameter 90, 120 and 260 microns. The dose was measured in an extrapolation chamber using tissue equivalent electrodes. The beta dose from the irradiated particles delivered to a segment of tissue can be calculated using a rate law derived from the experimental values.
