To accomplish these objectives a tentative program of operation for each phase is suggested. During each phase of operation it will be essential to monitor the radioactivity and identify the radioisotopes found in the plants and animals as a result of the past and pending bomb detonations. Collections should be made about the atoll at numerous locations to establish the level of natural and residual radiation from previous tests in order to form a base-line for evaluating the coming series of tests. Following the tests it will be essential to map the distribution of the amounts and kinds of radioactive materials in the plants and animals. It is important that additional basic information be gathered on the following: 1. The distribution of the radioactive material by currents, winds, and biological cycling should be studied. 2. The selectivity and concentration of radioactive materials by various organisms should be evaluated. 3. Studies at the test site should point the way for subsequent laboratory studies under controlled conditions. 4. The data obtained from the field study should be of value in the solution of practical problems such as:
