This invention relates to a method for analyzing the energy spectrum of alpha particles in mixed radiation fields using a CR-39 track detector based on step-by-step etching and energy attenuation. The method first etches the CR-39 with a potassium hydroxide-ethanol-water (PEW) solution, utilizing the significant differences in the tracks revealed by protons, alpha particles, and heavy ions to effectively distinguish alpha particles. To address the problem of a narrow energy window for alpha particle track revealing, this invention proposes a novel etching and identification method. By placing a series of energy-degrading sheets of varying thicknesses in front of the CR-39, the wide-spectrum alpha particles are attenuated to the optimal detection range in the spatial dimension. Simultaneously, through multiple step-by-step etching sessions of varying durations, the measurement window is broadened in the temporal dimension, allowing for the acquisition of the alpha particle energy spectrum in a short time, ultimately achieving accurate reconstruction of the alpha particle energy spectrum. This invention achieves high-purity identification and accurate measurement of alpha particles across a wide energy spectrum in complex mixed radiation fields, offering advantages such as low cost, ease of operation, and reliable results.
