Figure 6

Secondary neutron dose at the proton eye snout. External neutron doses equivalent to the proton absorbed doses (mSv/Gy) according to the distance at the surface, in the middle of the SOBP (1.64 cm), and after the distal fall-off (60 cm) in the water phantom. Circles show the results at the surface without the SWX207HD5. Rectangles show the results at the surface with the SWX207HD. Triangles show the results at a depth of 1.64 cm without the SWX207HD5. Plus signs show the results at a depth of 1.64 cm with the SWX207HD5. Diamonds show the results at a depth of 6 cm without the SWX207HD5. Crosses show the results at a depth of 6 cm with the SWX207HD5.
