contaminated foods, and (c) excluding areas where relatively little fallout occurred, but into which may be transported highly contaminated food wee Le and/or water. After longer periods of time during which the gamma dose rates in an originally highly contaminated area have decreased to acceptable levels, it probably would be necessary to ‘evaluate the residual | i contamination for the bone seeking radioisotopes, especially strontium-90. NUCLEAR WEAPONS TESTING Since 1951, the United States has conducted 11 series of nuclear tests, five at the Nevada Test Site and six at the Eniwetok Proving Ground, for a total of more than ©detentions. rently underway at the Nevada Test Site. A sixth series is cur- The fallout on the inhabitants of some of the Marshall Islands in March 1954 (which will be discussed by others) and fallout on some Japanese fishermen, have been the major effects off the testing areas. The oniy other off~site damage has been in the United States where the blast wave has caused minor structural damage for which about $45,000 has been paid in claims,@3 and faliout that occurred on some horses and cattle grazing within 20 miles of ground zero causing skin burns for which about $15,000 was paid. At the Eniwetok Proving Ground, where the larger devices are tested, the warning area covers nearly 400,000 square miles. This area is under constant surveillance during the time of testing both by surface ships and by aircraft. Starting two days prior to a detona~ tion, the search is intensified in the sector of probable fallout. any transient ship is located in the warning area, it is advised to leave and the detonation is dezayed until it is clear.: - 25 - If
