Probability distributions for the art-specific thyroid follicle models. (a) Single-hit specific energy distribution, f(z ₁), for the mouse, rat and human models per ²¹¹At decay that hits the target nuclei with ²¹¹At homogeneously distributed within the follicle lumen. (b) Lineal energy distribution, f(y), for the mouse, rat and human models per ²¹¹At decay that hits the target nuclei with ²¹¹At homogeneously distributed within the follicle lumen. (c) Single-hit specific energy distribution, f(z ₁), for the mouse, rat and human models with ²¹¹At homogeneously distributed within the follicle cell nucleus. This is the self-absorbed specific energy distribution for the follicle cell nucleus. For panels a, c and d, the bin size used were 20 mGy; for panel b, the bin size used was 5 keV/μm, and the area under each curve was normalised to 1. (d) Single-hit specific energy distribution, f(z ₁), for the mouse, rat and human models per ²¹¹At decay that hits the target nuclei with ²¹¹At homogeneously distributed within the follicle cells.
