Description

The damage caused in scintillating crystals by fast hadrons has been observed to present specific contributions, that are absent in a purely ionising radiation field. All the observed features point towards the creation of so-called "fission-tracks" in materials whose elements lie above the fission-threshold. In this paper we present visual evidence for the creation of fission tracks in Lead Tungstate, using techniques that have been developed in geochronology and are commonly used for rock dating.
