Show Fallout Figures Recorded From Two Blasts Tuesday, Mar. 29, .for the first time In the history of the world two atomic devices wore detonated deton-ated In one day, according to word received by the United States Atomic Energy Commission Commis-sion test information office at Las Vegas, Nev. The western horizons In three states and particularly in Nevada Neva-da and southern Utah were lit up at 5:55 a. m. MST by the largest lar-gest detonation in the current series at Yucca Flat. At 11 a. m. MST another detonation, an air drop, was released. The first shot was a 500 foot tower detonation. Biggest concern to residents of southern Utah, however, was the amount of fallout that was recorded re-corded here following the blasts. According to the offsite monitoring moni-toring team located in Cedar City, Dr. Clinton Powell and Edgar Seagle, fallout in this vicinity was first detected at approximately approxi-mately 11:45 a. m. Tuesday from the atomic cloud that passed over the southern portion of the state. Maximum Readings Maximum readings reported In this area, shown in one-year biological bio-logical doses, were: Caliente, 0.12 roentgens; Kanarraville, 0.2 roentgens; ro-entgens; Cedar City Airport, 0.1G roentgens; Beryl Junction, 0 84; St. George, 0.15; Panacq, 0.4S, and the highest reading recorded -off-site In the series was at Alamo, Ala-mo, Nev. at 1.4 roentgens. The Alamo reading of 1.4 biological bio-logical dose in one year may be compared with the test organization's organiza-tion's very conservative guide, according to the report, of 3.9 roentgens ro-entgens in a year, or with exposure ex-posure in chest X-rays which range from 0.1 to 1 roentgens. Dr. Powel indicated that the fallout In this area was still in evidence Wednesday mor,nJrg He expressed the belief, however, that the snowfall of Wednesday would contribute highly to washing wash-ing the radio activity away and returning the area to a normal background reading. He advised , prospectors with sensitive geiger counters that readings would be out of prospective, pros-pective, because of the fallout. He did not say how long it would last. That can not be determined determin-ed In advance, he pointed out. |
