Abstract:
Abstract Some tracks are obtained in several plastics using an organic solvent track etching procedure. The described results are those obtained with ethyl alcohol. The samples (PMMA) are submitted to pure alcohol effect then to water effect. By this way one can get 6 MeV α-tracks but the phenomenon is not reproducible. The most frequent observations are described.
