Single-hit mean specific energy for the single thyroid follicle model. The single-hit mean specific energy, 〈z₁〉, for the 8- (blue filled circle), 6- (red filled square) and 4-μm (green filled triangle) follicle cell nucleus per decay. ²¹¹At was homogeneously distributed within the follicle lumen. The follicle lumen diameter, d, varied between 10 and 500 μm. Error bars indicate SD and are smaller than the data symbol when not visible.
