Thehighest dose is calculated <strong>for</strong> grid cell E11 (Vault 20) at 2310 (9.9 x 10 -4 mSv) <strong>and</strong> isprimarily associated with exposure to 239 Pu, 94 Nb <strong>and</strong> 240 Pu. Similar to the in<strong>for</strong>malscavenger results, the main exposure pathways are inhalation <strong>and</strong> external irradiation.The smallest dose (5.6 x 10 -4 mSv) is calculated <strong>for</strong> grid cell E10 (Vault 17).Galson Sciences Ltd 41 21 March 2011
