Abstract

Makrofol DE1-4C detectors were exposed to fission fragments and alpha particles (of energy 0.5–3 MeV) from a 252Cf source in a vacuum chamber. The exposed detectors were etched in 6-N NaOH solution at 70 °C to measure etch induction times. An optical microscope was used to investigate various charged particle tracks and diameters in Makrofol detectors. The etch induction times for alpha-particle and fission-fragment tracks were obtained from the intersections of extrapolations of a graph of track diameters with time. The obtained results will be very useful in nuclear track studies, as well as nanotechnology fields.
