Abstract : A new criterion for track registration in polymer charged particle detectors is proposed. Based on the concept of the restricted energy loss rate, it indicates that only energy transfer collisions of 1.0 plus or minus 0.2 keV and less are important in track formation. For track registration in cellulose nitrate and Lexan, a charged particle must have a restricted energy loss rate of 1.1 and 3700 MeV sq cm/g respectively. This threshold appears to be sharp in both materials. (Author)
