principally ionic rather than particulate. Detergents and ion-exchange carriers were effective in removing some remaining activity.
6.2.7 Protection of Personnel in Radiation Fields. Since the operation of the ships and
their subsequent decontamination involved the exposure of a large number of personnel to
radiation, a number of studies were performed on personnel protection and dosimetry.
In general, mission planning and survey readings wereeffective in limiting dosages to

between, prevented the spread of contamination. A study of a special multiple-shield
film-badge holder revealed that combination beta-gamma dosimetry was valuable, but
