This study compares measured ionization cluster sizes from alpha particles in tissue-equivalent media with simulations for liquid water. Findings show good agreement between experimental gas data and K-means algorithm results for water, validating the simulation approach.

Area of Science:

  • * Radiation Physics
  • * Biophysics
  • * Computational Physics

Background:

  • * Ionization cluster size distributions are crucial for understanding radiation energy deposition at the nanometer scale in biological tissues.
  • * Alpha particle interactions in tissue-equivalent media are complex, requiring accurate modeling and experimental validation.

Purpose of the Study:

  • * To measure ionization cluster size distributions produced by alpha particles in tissue-equivalent media.
  • * To compare experimental data with simulated distributions for liquid water using Monte Carlo track structure calculations.
  • * To validate the K-means algorithm for deriving cluster size distributions from experimental and simulated data.

Main Methods:

  • * Experiments were conducted using a 4.6 MeV alpha particle beam in the JET Counter setup.

  • * Ionization cluster size distributions were theoretically derived using the K-means algorithm.
  • * Monte Carlo track structure calculations with cross sections for liquid water were employed for simulations.

    • Main Results:

    • * The ratio of first moments for water to gas targets correlated well with the ratio of mean free paths for primary ionization.
    • * K-means algorithm-derived cluster size distributions for alpha particles in water showed agreement with experimental measurements in nanometer-sized nitrogen and propane gas targets.

    Conclusions:

    • * The K-means algorithm effectively models ionization cluster size distributions for alpha particles.
    • * The study validates the use of liquid water as a surrogate for biological tissue in microdosimetry simulations.
    • * Findings support the correlation between theoretical models and experimental data in radiation physics research.
