The objective of the Biostack experiment, which was flown aboard the Apollo 16 command module, was to study the biological effects of individual heavy primaries of cosmic radiation. This was achieved by using a special sandwich construction, where physical detector sheets were stacked alternately with layers of biological objects in monolayers. Thus, it was possible to correlate each observed biological damage with the responsible heavy primary of known charge and energy loss. A broad spectrum of radiation-induced effects was observed on bacterial spores, plant seeds, and animal eggs. The severest damage was produced in shrimp eggs, which were hit by a heavy primary. None of the hit eggs developed to a normal adult. Development inhibition, malformations, and reduced fertility were the main effects observed. The information about the biological effectiveness of heavy primaries, obtained from the Biostack experiment, helps to estimate the radiation hazards of man in space during long-duration missions.
