here is a graphic representation of the radiation doses measured in the CST from May 2001 to March 2003: -z (approx. z = -40cm) 94: 64,8 Gy 93: 74,5 Gy ^ y | | 90 89 x<----+ 92 91 59,1 Gy 76,9 Gy 67,2 Gy 46,1 Gy 87: 79,3 Gy 88: 53,4 Gy +z (approx. z = +40cm) 81: 51,8 Gy 82: 77,7 Gy ^ y | | 83 84 x<----+ 95 96 58,3 Gy 71,2 Gy 48,6 Gy 25,9 Gy 86: 55,0 Gy 85: 41,3 Gy ------------------------------------------------------------------- Side view: 81: 51,8 Gy 94: 64,8 Gy 82: 77,7 Gy 93: 74,5 Gy ^ y | | z<----+ 86: 55,0 Gy 87: 79,3 Gy 85: 41,3 Gy 88: 53,4 Gy ------------------------------------------------------------------- Top view: 96: 25,9 Gy 91: 46,1 Gy 95: 48,6 Gy 92: 67,2 Gy z<----+ | | V x 84: 71,2 Gy 89: 76,9 Gy 83: 58,3 Gy 90: 59,1 Gy Here are some averages I calculated: Averages: Forward (+z): 53,7 Backward (-z): 65,2 Inner (small r): 68,8 Outer (big r): 50,1 Top (+y): 67,2 Bottom (-y): 57,3 Left (+x): 66,4 Right (-x): 47,0 so, there is approximately: * 21% more radiation at -z than at +z, * 37% more radiation at small radii than at big radii, * 21% more radiation at the top than the bottom, * 41% more radiation at +x than at -x (which is certainly a reflection of the fact that at +x the dosimeters are far closer to the beam than at -x).
