the development of procedures, and the training of personnel. Included also was the responsibility for installation and operation of communications and electronics systems for monitoring and displaying the air situation, for air warning and control, and for navigational aids. Corollary and support functions included the operation of air surveillance and limited air defense, the provision for admimistrative and proficiency flying for all JOINT TASK FORCE THREE personnel, the operation of an air intra-island transport using liaison aircraft and helicopters, and in conjunction with Task Group 3.3. a Search and Rescue activity. Additional responsibilities involved the provision for weather reconnaissance, analysis and forecasting, and for documentary film coverage for all JOINT TASK FORCE THREE activities.

Evaluation of ground radiac Corporate Source: Signal Corps Engineering Labs., Fort Monmouth, NJ Publication Date: May 1952 p 245 Report Number(s): Document Type: (USA) AD-A-995251/6/XAB Report Language: English Journal Announcement: EDB8510 Availability: NTIS, PC All/MF AO. Subfile: BRA (Energy Research Abstracts). Country of Origin: United States Country of Publication: United States Abstract: Prior to Operation Sandstone at 1948, radiac equipment had been designed for laboratory and plant use. After Sandstone, the Department of Defense (DoD) and the Atomic Energy Commission (AEC) developed a great variety of radiac expressly for military and civil-defense appplications. It is extremely difficult to simulate conditions existing at the time of, and soon after, an atomic explosion; therefore, it is very difficult to evaluate radiac completely in the laboratory or in the field without an atomic explosion. Only by testing at an atomic proving ground is it possible to determine the true worth of service equipment. The work reported in this volume includes analyses in stateside laboratories and experiments at Eniwetok during the spring of 1951. Twenty-one types of dosimeters, sixteen types of survey meters, and one mobile radiological field laboratory, ‘and four Jaundry-monitoring arrangements were tested. These included equipment development by, or under the sponsorship of the Army Signal Corps, the Army Chemical Corps, the AEC, and the Bureau of Ships of the Navy. Conclusions are reached and recommendations are made with regard to adequacy of the equipment, adequacy and feasibility of existing military characteristics, direction of future developments, and necessity for future tests and improved test methods.
