HZE-Particle Dosimetry (COS 782-18)
Principal Investigator
Research Area:
Radiation biology
Species Studied
Scientific Name: Not applicable Species: Not applicable


This experiment was designed to measure the high-LET particle radiation aboard the Cosmos satellite. One of the specific objectives of this experiment was to determine the number of heavy particles with charge of Z>=20 stopping in a one cubic centimeter volume. This information was necessary in order to assess the feasibility of performing U.S. experiments concerning heavy particle track effects in rodent brains aboard future U.S.S.R. Cosmos satellite flights.
