AbstractIn this work, the damage caused by the passage of alpha particles inside the CR-39 nuclear detector material on its chemical structure was studied. All samples at room temperature using a 241Am-Be neutron source with a flux of 5^10 neutrons.cm-2.s-1 were neutron-irradiated. In the CR-39 nuclear track detectors, chemical etching is a critical step in expanding latent tracks. At 70 °C, a NaOH in 6.25N etchant was found to be useful in expanding alpha traces in the CR-39 detector. The track depths of the Alpha particle as a function of etching time for the various energies were increased as etching time increases. The current study uses the nuclear track detector technique to estimate the range of alpha particles. Track etch rates are frequently determined using 2-dimensional photographs of track openings (diameter) or etching time data. The chemical structure along latent tracks and the track formation process were investigated in PADC(poly allyl diglycol carbonate). The findings showed that the measurement of bulk etch rate values by the weight method was 1.42 ± 0.02 μm/h. In addition, the results for the alpha particle range from 4.47 ± 0.05 and 5.8 ± 0.19 μm for alpha energy1.2 MeV and1.47MeV,respectively
