Generous use will be made of photography to describe the areas monitored. Several of the islands of Bikini Atoll have been exposed to the cratering effects of past tests. Eninman Island, which showed some of the higher radiation levels in 1964, is such an island having had two events, Koon ye UCRL-12172) and Zuflp, which resulted in cratering a portion of the islan Portable —_— Pe mp ey instrument measurements of gamma and beta-gamna levels will be obtained in the vicinity of the cratered portion of each such island. Debris and any remaining man-made objects, particularly those that may have utility oe building materials, will be checked for surface contamination and induced radioactivity through measurement of gamma, beta, and alpha levels. Loca- tions showing higher levels for the August 1964 survey will be remonitored. ie meron These locations are shown in the field notes prepared during the earlier survey. Where practical, island locations with lower levels, as specified in these notes, will also be remonitored. soy I > Documentation. Appropriate procedures will be employed to assure proper calibration of portable instruments and to provide an acceptably small degree of uncertainty in measurements. Records will be developed “EERIETNE “SAREERIEnENEE Ns ereRREHE = Re identifying the time and location of each measurement, and the instrument type and number and the expected accuracy of the measurement will be shown. Records will also be developed describing the use of controls and the processing of dosimeter devices with expected accuracy for each data point. TOMER ien peetin -atie “oe . 924612108 | PO2Z C ‘N
