Space Radiation Dosimetry Aboard Cosmos 1129: U.S. Portion of the Experiment (COS 1129-14)
Principal Investigator
Research Area:
Radiation biology
Species Studied
Scientific Name: Not applicable Species: Not applicable


The purpose of this experiment was to provide a comprehensive picture of the radiation exposure experienced by the Cosmos 1129 spacecraft and its contents. The measurements included and distinguished between the low- and high-LET radiation components, and also provided an approximate determination of the neutron exposure.
