Figure 4: Surface Plot of Flux from Rack Figure 4 is a surface plot of the total gamma flux from just outside the rack. Looking at the “hot� red locations, we can see that these correspond to the active source slugs, and their positions are clearly defined. The inactive slugs and the two empty pencil locations effectively separate the sources from each other, so much so in fact that the active slug locations can be easily identified by the magnitude of the flux. Clearly, the closer you are to the source, the higher the flux will be. Thus, the highest concentrations of photons in this figure are located around the positions of the active source slugs in the rack. Note that the cobalt rack faces two directions, one in the direction of the Gamma Irradiation Facilities and one in the direction of the UMLRR pool. Therefore, two sets of flux magnitudes as a function of distance from the rack were generated, one in the UMLRR water and one in the direction of the facilities. The flux profiles for the water model direction can be seen below in Figures 5 and 6.
