Keo hy Spring 1953. (The skir damage observed or shee; in the spring 1953 was not established to be beta turns,! Bowever, the exact positions of the anizals in relation to known mmowunts of fallout are act elear, Following the last detonation of the spring 1952 series at the Kevada Proving Grounds, about one half of « herd of 150 head of cattle were Sound to have evidence of beta tions. They vere thougt to have been 15-20 niles from ground sero in Kawleh Valley to the rortheast and to have been exposed to fallout from the last detonation. Gose rate readings (14 FT ar « 300 foot tower) Highest taken along a dirt road runing this valley, integrated lengthwise through to 75-10%infirity gamna doses, During Upshot-Znothole, 16 horses showed skin lesions over the back and eye daxage was noted ina few, The best evidence indicated that the horses vere some 81 miles to the east o” grown sero on 17 March 1954, where the fallout occurred from the first detonation (16 KT on a 300 foot tower), Radiation levels in this ares arw not know with certainty but the fallout oceurred in a narrow band and vas carried by relatively high Velocity winds so that it probably fell an tha horses at a tire less than ene hour. If ac, probably more than ons~ialf of the infinity dose vas delivered during the next day.
