Whole-body gammaspectros- copy was carried out with the 21-ton steel room placed in the after part of the tank deck, with the air conditioned electronics room and the shower facility close by. The people to be examined entered the ship via the forward ramp directly onto the tank deck, proceededto the showerfacility where they disrobed, took a complete soap and water shower, and donned disposable paper coveralls and slippers, and then proceeded to the 21-ton steel room, where a 10-min gammaspectroscopy count was obtained. Phonograph music was piped into the steel room during the procedure. The people, except very young children, showed no evidence of fear or claustrophobia and appeared to enjoy the procedure. Further description of the gamma spectrographic methods will be presented later. The diagnostic x-ray machinewas also set up in the tank deck. Rongelap Village. As in 1958, the dispensary. schoolhouse, and council house were used for the examinations(Figure 6). Hematological and other laboratory procedures and ophthalmological examinations were carried out in the dispensary (Figure 7), Medical histories were taken and physical examinations were made in the schoolhouse. The council house provided areas for an administrative center, for collection of urine sam- ples, and for laboratory use by the University of Washington group. History and Physical Examinations Histories were taken by a Marshallese practitioner with particular emphasis on the interval history during the past year. A special survey was conducted by the pediatrician to ascertain more accurately the birth dates of the Rongelapese, particularly the children. Complete physical examinations were carried out including examinations of the children for growth and development (anthropometric measurements, and x-ray examinationsoftheleft wrist
