ARNT TORT Ce Re ala “ROP-SREREP- 3, I do not have the figures as to the number of persons and the costs involved in the high-altitude program. Such costs are almost impossible to segregate in that certain construction and instrumentation is used for several experiments and many personnel work also on more than one experiment. However, I estimate that cost must run between $10 and $20 million and I would estimate the maximum numbers of people directly involved in ecientific effort and support to be in . the range of 1,000 to 1,500. Measurements contemplated are as follows: | a, From peds shed from the Redstone missile rockets, to measure thermal, gamma, and neutron phenomena at various distances from the blast. b. By rockets emplaced in space around the higher shot, to secure similar measurements. ec, Prom aircraft, to measure through photograrhy and other instruments the rate of growth, and spectrum, of the fireball together with the intensity of the various “phenomena at the airoraft altitude, ad. Through one rocket for the higher altitude shot to capture a debris sample for analysis to determine feasibility of getting yield in this manner. Also from one rocket on the higher altitude shot, to attempt to transport radio signals through, and around, the cloud. e. From stations on the ground, to photograph the fireball and determine its spectrum and to determine thermal effects, etc., received on the ground near detonation point. f, From close-in and distant electromagnetic and microbarograph stations, listening stations, and radio and radar transmission receiving stations to determine: detectability through these high altitude detonations, and interference of such detonations with radio and radar activity. 4, The Eniwetok Planning Board reviewed some months ago the thermal effects to be expected from the detonations and judged them to be reasonable. In the briefing of the Commission on February 28, 1958, Dr. Ogle indicated that the danger to eyes was expected to be in the neighborhood of 100 miles, and ~ 2.
