High-Z Particle Cosmic-Ray Exposure of Apollo 8-14 Astronauts
Abstract
On Apollo missions that individual astronauts' high Z particle exposure was measured by means of Lexan foils located in the passive dosimetry packs carried on the chest, thigh, and ankle of each astronaut. The report deals with measurements obtained on Apollo flights 8-14. Data is presented on the high Z track fluences, the stopping particle densities, and the particle integral LET spectra. The LET spectra, in turn, are used to calculate the fractional cell loss, FCL, of the human kidney (Tl) cells arising from the high Z particle exposure. The measurements, on subsequent missions, show a consistent and a significant increase in the observed high Z particle exposure.
