Twenty single particles separated from a 20-liter sample of rain collected in Osaka, Japan, shortly after the 14 May 1965 test explosion of the Chinese nuclear device, were analyzed radiochemically. The abundance pattern of the fission products in these particles resembled the shape of the mass-yield curve for the thermal neutron-induced fission of uranium-235, except for the facts that cesium-...

Alexandra C. Miller et al., Preconceptional Paternal Exposure to Depleted Uranium: Transmission of Genetic Damage to Offspring, Health Physics 99(3), 371-379, 2010 (September) Male transgenic mice with embedded DU pellets were exposed to low (2 DU pellets), medium (4 DU pellets) and high (6 DU pellets) doses of DU over a period of 7 months. They were mated to nontransgenic female mice at 7 mont...

This work illustrates a methodology based on photon interrogation and coincidence counting for determining the characteristics of fissile material. The feasibility of the proposed methods was demonstrated using the Monte Carlo-based MCNPX/MCNPPoliMi code system capable of simulating the full statistics of the neutron and photon field generated by the photon interrogation of fissile and non-fiss...

This report provides a review of the ICRP model for the systemic biokinetics of uranium absorbed to blood, identifies key model parameters that affect urinary excretion, considers uncertainties in values for these parameters, and determines the effect of these uncertainties on dose assessments based on urine measurements. A parallel study of the application of the ICRP respiratory tract model t...

Measurements of uranium excreted in urine have been widely used to monitor possible exposure to depleted uranium (DU) by personnel who have served in areas where DU munitions were used in conflicts. A study has been carried out to provide guidance on the most appropriate parameter values to be used in assessing intakes and doses from urine samples taken at long times (100 to 10,000 days) after ...
