Fig. 6From: A random walk approach to estimate the confinement of α-particle emitters in nanoparticles for targeted radionuclide therapyBased on the results of Rayleigh (1919, see Annex) the cumulative probability was calculated that in a 3-dimensional space a sequence of N = 2 and N = 3 random steps with equal length R and arbitrary orientation end in a distance r from the origin of the first stepBack to article page
