Summary

Ilford G.5 emulsions in radiation packs carried by the astronauts in their space suits on the Earth-orbital mission Apollo VII and the first lunar mission Apollo VIII were scanned for tracks of heavy nuclei. As the 'microbeam' effects of heavy nuclei in living tissue center upon the high Z numbers, the scan was limited to Z numbers of 20 and higher. Greatly different fluxes are found on the two missions. The findings demonstrate the great difference in the make-up of the radiation environment in a near-Earth orbital and a deep-space mission and point out the need for a better understanding of the radiobiological significance of total body irradiation with heavy nuclei if the exposure status of an astronaut from accumulated exposures to the deep-space radiation environment is to be assessed accurately.
