EXPERIMENT INFORMATION

Effects of Cosmic Particle Radiation on the Ear (A17-4)
Principal Investigator
Research Area:
Radiation biology
Species Studied
Scientific Name: Perognathus longimembris Species: Mouse, Pocket

Description
Objectives:

Hemorrhage had occurred in the middle ear cavity of mice subjected to increased oxygen partial pressure in K02 tests during hardware verification, and hemorrhage and/or exudative materials were noted in all flight and flight backup mice. The main objective was to determine if hemorrhagic materials in the middle ear cavities and the cellular reaction there differed in any way in the flight animals compared to the flight backup controls. This study was also to investigate if the otoconial apparatus of mice flown on Apollo 17 had been altered as a result of weightlessness, and to determine whether any structures of the inner ear had been injured by cosmic ray particles.
