I am not convinced that the effect is purely cumulative anyway. In other words, a lower intensity (and lower energy) beam for longer might not do as much damage as a brief pulse from a high intensity, high energy source. Silly example (using visible light, not X rays), I can look at the output of a normal red LED for many hours without any eye damage. But shining a high power laser in my eye for a fraction of a second would blind me. -tony
