A plot of the Apollo TLI orbit showing the transition through the Van Allen Belts. The belts are shown in the following contours Blue=0.0001 rads/sec; green 0.001 rads/sec; yellow 0.005 rads/sec; orange 0.01 rads/sec; red 0.05 rads/sec. These levels are for an unprotected target in open space. Total transit time across the blue zone is approximately 90 minutes.
Thanks to the excellent Bob B for doing the maths to plot the orbit.
