It is proposed to register the penetration of cosmic rays into biological material by the photographic emulsion technique. From a study of the tracks, an examination of the biological effects of cosmic rays would be possible. To introduce the particle-sensitive material into the cellular tissue, a small amount of liquid silverhalide emulsion is injected. After processing, this should then serve as indicator for penetrated particles.

Preliminary tests were carried out on dead human skin, into which a few of emulsion were injected. The specimens were then dried, exposed to a beam of neutrons and developed by temperature-development. Microscopic inspection of thin sections from different specimens shows, in reproducable manner, tracks of recoil protons. Further experiments are to be carried out on living material.
