0977-6Version 16.1.6 B7 – SmallholdingFigure 6.24, Figure 6.25 <strong>and</strong> Figure 6.26 show the total annual dose to a smallholderat different locations on the site in the years 2230, 7000 <strong>and</strong> 12000, respectively.Exposure via the foodstuff pathways dominates the total dose to the smallholder.This is due to exposure to 14 C in plant material <strong>and</strong>, to a lesser extent, exposure to 36 Clin plant material <strong>and</strong> exposure to 14 C <strong>and</strong> 36 Cl in goat’s milk (Figure 6.27). Vaults 15to 18 contain high 14 C activities <strong>and</strong> relatively low 234 U activities, unlike Vaults 8 to14, <strong>for</strong> which exposure to 222 Rn associated with the decay of 234 U dominates the totaldose (<strong>Hicks</strong> <strong>and</strong> <strong>Baldwin</strong>, 2011, Section 7.1.6). The maximum calculated annual dose(5.4 mSv) is observed in Vault 17 (cell E10) at 2230; the smallest annual dose is1.6 mSv in Vault 20 (cell F11) at this time. By the year 7000, the calculated annualdose in each grid cell is 3.4 mSv or less, <strong>and</strong> is no more than 2.4 mSv by the year12000.6.05.0Dose (mSv)4.03.02.01.00.0A & B10C & D11E & FFigure 6.24Total annual dose to a smallholder (B7) in the year 2230 (Case A).Galson Sciences Ltd 36 21 March 2011
