The area is generally rectangular in shape and com- prises roughly 375,000 nautical square miles. While slightly smaller than the dange> zone used in the latter part of the 1954 series, it is many times larger than the initial area used in 1954 and has been reoriented slightly for increased safety. Lewis L. Strauss, Chairman of the Atomic Energy Commission, has announced that the forthcoming series of tests Will involve weapons generally smaller in yield than those tested during the 1954 test series. It is anticipated that | the energy release of the largest test will be substantially below that of the maximum 1954 test. There will be a post operation radiological survey of the control area. Although it is estimated that most, if not all, of the area will be released from control by the end of August 1956, it is not now possible to fix a final effective date. Effective April 20, all shits, aircraft and personnel are cautioned to remain ciear of the area enclosed by the following georgraphic coordinates: 7 18° 30' N 158° 00! E - 18° 30! N 172° OO!
