Description
Summary:The beta energy emission rate from neutron-irradiated, uranium-235-carbide particles was measured by chemical dosimetry. The particles were suspended by vigorous stirring in ferrous sulfate solutions. The oxidation of ferrous to ferric ion was the chemical change measured, this change being related to the energy absorbed by the solution. Good agreement was obtained between the existing calculated and the experimental values of beta energy emission rate. From these data, simplified equations were derived for calculating beta energy emission rate as a function of particle size and time after fission, and they are presented. (Author)
