0977-6Version 1Vaults 15 <strong>and</strong> 16 (grid cells C10 <strong>and</strong> A10) contain high initial 239 Pu <strong>and</strong> 240 Puactivities <strong>and</strong> drilling into these cells would result in relatively high dose to theintruder via the dust inhalation pathway. Figure 6.3 <strong>and</strong> Figure 6.5 indicate thecontribution to dose of the main radionuclides <strong>for</strong> intrusions in grid cells A10 <strong>and</strong> C10occurring between 2230 <strong>and</strong> 7000. Figure 6.4 <strong>and</strong> Figure 6.6 show the dose fromeach exposure pathway. The potential dose from drilling at these locations (C10 <strong>and</strong>A10) is dominated by plutonium inhalation exposure.0.000160.000140.00012Dose (mSv)0.000100.000080.000060.000040.000020.00000A & B10C & D11E & FFigure 6.1Total dose to the driller (B1a) from a drilling intrusion at differentlocations in the year 2230 (Case A).Galson Sciences Ltd 22 21 March 2011
