Jelete is similar in almost all respects to Lukcj. The radiation survey was accomplished by encircling the island about 100 ft. inland. Readings with the CG-M counter ranged from 63 to 130 ur/hr. No soil samples were obtained. G. Oroken - Bokaetoktok - Bokdrclul These small islands, the most westerly of the southwest group, exhibited similar general characteristics - black coral rock shores, dense vegetation. mcist. highly organic soil, and quite large bird populations. The islands were essentially undisturbed by construction and other similar activities connected with the testing operations. Radiation levels on these islands were scmewhat lower than on Lukoj and Jelete. On Oroken the measurements around the island about 50 ft. inland ranged fror 17 to 30 ur/hr. Closer to the center of the island the levels were around 40 ur/hr. The highest level measured with the G-M counter was 43 wr/hr. On Bokaetoktck the levels were oniy si-_ghtciy lower, ranging from 10 to 23 ur/hr with a raximunm ot 30 Ux/hr near the center. On Bokdrolul fairly unifcrm readings of from 24 to 36 ur/hr were recorded with the scintillation covnter. A similar range was found with the G-M counter with one measurement of 50 ur/hr Lower levels of about 10 ur/hr were typical near the ocean or lagoon shores No soil samples were obtained from these islands.
