observed over the intervening years. (Graphics No. 4) Other "beta burns" have been observed on a few cattie in 1952, on horses in 1953, and one horse in 1955 in Nevada. All of these, as well as the Alamogordo cattle were grazing within 20 miles of ground zero where there was relatively heavy local fallout from the tower bursts. Crude estimates suggest that the external whole body exposures in these same areas would have been in excess of 75 roentgens from gamma rays?’. re he The principal example of skin damage was on the Marshallese people following the heavy fallout on March 1, 19544: , (Graphics No. 6) The most damaged areas were (a) in the regions of hair on the head punt (oiled), (b) folds of the moist bare skin such as the neck region and inner elbow, and (c) tops of the feet where the fallout material re- Faye he mained in place. The extent of skin damage to the most heavily exposed group may be summarized as follows: 45 individuals - superficial lesions 13 individuals - deep lesions __6 individuals Total no lesions 64 35 individuals (of the 64 above) some degree of epilation Hair of normal color and texture has regrown and all lesions have healed without visible effects except for some scar tissue behind the ear of one man, marking the location of a previous deep lesion and permanent loss of pigment in the healed areas in individuals. Additional cases of skin damage from fallout were observed on some Japanese fishermen aboard the Fukyryu Maru and some American 12. (7
