Developeent of the fila badges of the personnel involved In Zebra Test operations disclosed that Lang and S&l&gna received appreciable doses. The film badges were developed at Enivetok after the sen had already departed for the States, but the infomation vas passed on to the laboratory by teletype (see Exhibit F). The Injuries received by Lang and Balagna were sufficient so that no question ms Involved in the diagnosis, and altogether Lang, Balagaa, Stanley and Sattlsahn were hospitalized on 16 May 1S&8.
