proceburcs \°) Gamma ré, spectrum analysis and strontium analysis on ail and arrc-root samples were performed at the WERL in Honoiulu, dHawaii. coconut, pandanus, Pacific Operations Laboratory Edible portions of the samples were ground and counted without crying on a 4- by 4-inch Nal(T1) crystal multi-channel analyzer system. The spectral range covered was zero to two MeV. At the concentrations of !37Cs encountered in these samples, the counting error is approximately ten percent. (All errors referenced in this section are 2 sigma confidence level.) Following gamma spectrum analysis the samples were ashed and the inorganic residue was analyzed for 29°Sr. Due to the small amount of ash produced, it was often necessary to composite samples from adjacent locations. was performed on a low background beta counter. Counting The analytical error associ- ated with this procedure is approximately ten percent at the levels of 9°Sr encountered. All tritium and plutonium analyses were performed at WEPL, Las Vegas, Nevada. Tritium was determined by liquid scintillation counting of the water recovered from coconut milk and from selected soil samples. this procedure is 0.4 pCi/ml The minimum sensitivity for for five ml of recovered water. At this concen-~ tration the error term for the 2 sigma confidence level is + 100 percent. Analyses of the coconut milk and soil samples indicated the concentrations of tritium were Jess than the minimum detectable level. Plutonium analyses which were performed on soil samples were by radiochemical separation followed by pulse height analysis using a lithium-drifted silicon detector. The analytical error is approximately ten to fifteen percent. The analytical error associated with the results for plutonium on prefilters iS approximately + 25% at the 2 sigma confidence level. Unless otherwise specified each soil sample represented the top one to two inches of a one-square-foot area at each location. Prior to plutonium analysis, gamma ray spectrum analysis was performed to identify the most abundant radionuclides and to estimate their relative contribution to the total activity.
