411584 ENIWETOK RADIOLOGICAL SURVEY SAMPLE ANALYSIS PROGRAM PROGRESS REPORT APRIL 6, 1973 In the past month the quantities of each category of samples have been more Closely counted. The attached bar graph shows the most accurate count now available in parenthesis below the category name. The greatest change in count was that of the soil samples revised from 2,000 last month to 2,900 this month. This increase in the base number has biased the apparent growth of the bar graph which is expressed in percentage. However, the numerical increase was significant, e.g., the number of samples prepared increased from 1,050 last month to 1,602 this month. also be pointed out that there were in in the field survey. It should excess of 3,380 soil samples taken An examination of priorities and the need to analyze all of them is now underway, but it is presently anticipated that only 2,900 will need to be analyzed. Virtually all of the wet chemistry analyses to date have been done by the Air Force's McClellan Laboratory. The quality of this work has been outstanding and their sustained high rate of production is extremely important to the analysis program. The contract negotiations for LFE Environmental Analysis Laboratory and Eberline Instrument Company have just been completed and it is expected that after cross calibration with Poet Histocy Divisson REPOSITORY COLLECTION BOXNe.
