title: AgCl detectors in the Biostack II experiment aboard Apollo 17.
abstract: Two layers of AgCl detectors with a total surface of 90 cm2 were flown. Tracks of nuclei, from light (Z>4) up to the heaviest were recorded and could be distinguished by their geometrical trackwidths. The tracks were divided into five groups of atomic numbers, and their abundance was measured. Also the number of surviving nuclear stars was counted. 22.5 cm2 of the detector surface were covered with eggs of Artemia salina. The detectors could be developed without removing the eggs, so that the spots hit could be determined directly. The radiation effect on these eggs is being investigated.
