= are given inTable 2,65~-1, The H fl hour values were deterained using -1.3 ag the garma-decay exponent as detercined fron the curves of Fig. 2.65-2. The wv ae roy points on YVONNE and WIIMA are snown in Pig, 2,65=3 along with the corresponding H # 1 hour readings. Fig, 2.65-4 shows the H # 1 hour average dose rates for the seven islands surveyed, By Garma dose rate decay was.determined by counting gross fall" FE Decay Deta: out semples with a Jordan Survey Meter mounted in a sad pig for constant geozetry. A typical garsa-decay curve is shown in Fig, 2.65-5, A typical beta~ dzcay curve is shown in Fig. 2,65-~6. Radiochemistry: GsNE. Ground scoop samples were recovered from Sites WILMA end Another sample was retrieved from a depression in the canvas oo | an ~t abandoned truck at Site GzNE, It was discovered that all the particles fren the truck canvas were radioactive, while very few of the particles from the ground ‘probable for particles other than fallout to be collected at the heisht of a “rs ek cab, Csd to the belief that this ssuple is vep.csentative of the fallout Sa that erca. AL of these sanples were size -gro ied into various size fracitccs, and radiochemical analyses for Np??? and Mo’? were performed on each fraction. reom the enalysis, the following ecncl-sions wore dicvas 1, peed fractionates with isspect to Mo? as a function of particle -ize, As shown in Table 2,45.-2, the ratios of wpe to Mo?? and the capture/fission vstihos, whoich are proportional to then, of the sample increases, appear to decvcase as the parvicle sine Even the lowest value, 0.14, is almost twice the 0,936 value reported by LASL for a cloud sample. 2. The individual contributions of Np©?? end Mo79, in relative units, to the total beta activity of the semples generally increase with increasing Parte o dele size. corienideE LANL RG aS? ~ 34 - Lo
