Radionuclide Fractionation in Air-Burst Debris

  title={Radionuclide Fractionation in Air-Burst Debris},
  author={Edward C. Freiling and M. A. Kay},
Abstract : Radiochemical data from fractionated samples of airburst debris are correlated logarithmically. The correlation slopes are measures of volatility. These are compared with slopes observed in the cases of high-yield surface bursts and with thermodynamic calculations of volatility. 
Short-range Dating of Fresh Nuclear Debris
FRESH nuclear debris particles were detected in ground air and rain water at Niigata, Japan, on May 11, on November 1 and on December 30, 1966. Without doubt, the particles collected on May 11
Uranium in Fallout Particles
THE activity of uranium in hot particles (highly radio-active fallout particles) collected on a roof at our laboratory shortly after several nuclear explosions was measured by uranium separation and
Geochemical Fractionation of Induced Radionuclides in Fresh Nuclear Debris through the Atmosphere—Np-239 and Co-60
The atmospheric fractionation of induced radionuclides is discussed in some detail on the basis of results obtained by making a radiochemical analysis of fresh nuclear debris originating from recent
Investigation on Correlations Between Fractionation Effects and Particle Size Distributions in Fission Product Samples
Abstract : After the third Chinese nuclear bomb test, radioactive aerosol was collected on fiber filters from the atmosphere at different altitudes. By comparing the measured negative beta-decay

Analysis of gamma-radioactivity of “hot particles” released after the Chernobyl accident
The radionuclide fractionation process in “fuel-like” hot particles from the fallout after the Chernobyl accident is analyzed. Some processes which can be responsible for different kinds of
Comparison of Relative Radionuclide Ratios in Debris from the Third and the Fifth Chinese Nuclear Test Explosions
OF the five first Chinese nuclear test explosions, No. 3 and No. 5 detonated on May 9, 1966, and December 28, 1966, respectively, have been the most powerful. According to the U.S. Atomic Energy
Europium-155 in Debris from Nuclear Weapons
The lithium-drifted germanium detector enables determination of europium-155 on a routine basis in environmental samples contaminated with debris from nuclear weapons. From measurements of
Chemical fractionation in systems condensing from the gas phase
The development of chemical fractionation in particles condensing from a gas is described in terms of the intrinsic properties of the components and their mutual interaction through the nucleation,
Fission product isotope ratios as event characterization tools Part I: Particulate debris, isotopic activity ratios
Abstract The main goal of this work is to develop quantitatively reliable tools that can be used to identify the origin of a nuclear event, e. g. discriminate between a nuclear explosion and an


Theoretical Basis for Logarithmic Correlations of Fractionated Radionuclide Compositions
A theoretical basis for logarithmic correlations of fractionated radionuclide compositions is described. Implications for nuclear chemical studies of bomb debris and application to the prediction of
Radionuclide Fractionation in Bomb Debris: The fractionation systematics for high-yield bursts at sea-water and coral surfaces are delineated.
The composition of fractionated samples from high-yield surface bursts is correlated logarithmically and the cloud sample was found to be rich in strontium- 89, and small degrees of fractionation between similarly behaving radionuclides are best tested by plotting the ratio of their f values against the fractionation index.
