The nuclear reactor from the Soviet radar reconnaissance satellite, Cosmos-1402, reentered the earth's atmosphere on 7 February 1983 and disintegrated over the South Atlantic Ocean. The reactor was powered by approximately 50 kilograms of uranium-235 (235U). In an effort to determine the fate of the reactor core, a series of aerosol samples were collected at altitudes between 27 and 36 kilometers in the Northern Hemisphere approximately 1.1 years later by high-altitude balloons. At an altitude…

Space industrialization
On November 15, 2021, a Russian anti-satellite test produced more than 1,500 pieces of orbital debris that threatened the crew of the international space station. The crew members sheltered in
Determination of impurities in uranium matrices by time-of-flight ICP-MS using matrix-matched method
The analysis of impurities in uranium matrices is performed in a variety of fields, e.g., for quality control in the production stream converting uranium ores to fuels, as element signatures in
Radioactive Particles Released into the Environment from Nuclear Events
A major fraction of refractory radionuclides, such as uranium (U) and plutonium (Pu) that are released during severe nuclear events including nuclear weapon tests, reactor explosions or fires, and
Sources Contributing to Radionuclides in the Environment: With Focus on Radioactive Particles
To assess environmental impact and risks associated with radioactive contamination of ecosystems, links must be established between the source term and deposition, ecosystem transfer, biological
Sharing insights from decommissioning in the space and nuclear industries
The danger posed by human-created, orbital debris has been well documented and there is a broad consensus that, if unchecked, such debris poses a significant threat to the future of space activity.
Toxicological Profile for Uranium
A Toxicological Profile for Uranium, Draft for Public Comment was released in May 2011 and supersedes any previously released draft or final profile, and reflects ATSDR's assessment of all relevant toxicologic testing and information that has been peer-reviewed.


Atmospheric Burnup of the Cosmos-954 Reactor
The atmosphere was sampled during 1978 up to an altitude of 39 kilometers to detect particulate debris from the reactor on board the satellite, and enriched uranium-bearing aerosols at concentrations and particle sizes compatible with partial burnup of the Cosmos-954 reactor were detected only in the high polar stratosphere.
Radioactive debris as a tracer for investigating stratospheric motions
Two meteorologically interesting radioactive tracers, Cd-109 injected in 1962 at 400 km by a rocket-borne nuclear device and Pu-238 resulting from the reentry burnup in 1964 of a nuclear powered

The stratospheric inventory of the plutonium-238 resulting from the disintegration of a nuclear auxiliary power generator (SNAP-9A) in early 1966 accounts for essentially all the plutonium present in
Determination of picogram quantities of Uranium in biological tissues by isotope dilution thermal ionization mass spectrometry with ion counting detection.
The procedure was applied to the determination of U in SRM 1577a, bovine liver, which was found to have a mean concentration of 709 +/- 13 pg of U/g (ts, 95% confidence limit), the lowest certified U concentration of any biological SRM.
