Fig 8. Parameter distributions of α particle tracks (3 nominal energies) compared to a boronated sample (SRM) and a 30 ppm ¹⁰B aqueous solution (similar track density).

Each distribution corresponds to 45–50 images (≈200 tracks per image). a) Area, b) Diamenter, c) Aspect ratio, d) Roundness (presented in logarithmic scale), e) Heterogeneity, f) Clumpiness (presented in logarithmic scale).
