explosure rates in the environs of Eniwetok Atoll, 2. To assure proper analysis of soil samples on an analytical basis and a correlative basis to provide meaningful data and evaluation/verification of the sample collection scheme and techniques. 3. To evaluate the soil and terrestrial radiation data to determine the limitations on interpretation and utilization of these data, 4. To provide, as an end result, a complete statement of the radiological conditions of the soils of Eniwetok Atoll and their contribution to the radiation exposure rate of the environment. In planning to accomplish these goals, every effort was made to utilize, to a maximum advantage, all of the background information and experience gained from the preplanning "research" effort. An implicit requirement to get the most effort from the least amount of money within the limited time period allowed and yet provide a valid result had a major impact on the soil program design. Cost estimates of around $80.00 per sample (plutonium/strontium) for radiochemical analysis for several thousand soil samples as well as similar quantities of samples from the biota and marine sampling programs engendered concern for affording statistically adequate numbers. The quantity of samples also required a realistic evaluation of the total national capability for their analysis. To provide a meaningful statement of the radiological condition of the soil of the 43 islands of Eniwetok Atoll under the above constraints would require maximum efficiency of sample collection design efforts and no l/ Reference TWX, MAJ.
