TT L rae pe (5.5) Q Using the above values of r, r= 0,923 i.€., the instrument is about 92 percent efficient, Thus the averase directional response correction factor is 1.99, inplying that the reading inside a homogeneous cloud or over a homogeneous plane source is about Jere rcent low for this average energy, which is roughly in the l-Mev region, For the very low energy component below 100 key, it is not known whether the relative directional respunse varies grossly fron the above, It is assumed here that it does not, The doses calculated in this report are therefore based!on this dblrectional correction, Comtining this geasetry faclur with the energy correction of Table 5.t for the H + 5,2 day spectrum and Shot 1, a total correction factor of 1.22 results which was used in the air-dose calculations in Section &.1 of this report, ma ' . a ‘ Riohaa FA T= ‘et de pas adie. :
