Before the survey at Rongelap, the team visited Kwajalein and Majurofor several days to carry out examinations on a number of Rongelap people who had movedto these Islands. A Trust Territory ship, the M/V Ran Anim, transported the team and equipment to Rongelap on March 4, 1962 (Figure 3). A tent had been set up on the Island and one of the village houses rented to serve as living quarters for the team. On arrival, after greeting the Magistrate and othervillage dignitaries, it was learned that the death of an aged woman had occurred the previous day, and that an autopsy was to be permitted on the body. Establishing living quarters and setting up laboratory equipment and examination facilities in addition to carrying out the autopsy occupied the better part of the first day. Late in the afternoon the funeral for the deceased took place. The medical examinations on the people began the following day. The examinations were carried out ashore at Rongelap Village. As in the past the dispensary was used as a laboratory for the hematological and other laboratory procedures. The adjacent school building was used for taking histories and performing physical examinations on the people. The council house next door was used for special examinations of the skin, urine collections and analyses, and x-ray examinations. HISTORY AND PHYSICAL EXAMINATIONS Histories were taken by a Marshallese practi- tioner and an interpreter, with particular emphasis on the interval history during the past year. A special survey was again conducted by the pediatrician to attempt to ascertain more accurately the birth dates of the Rongelap people, particularly the children. Complete physical examinations were carried out including growth and development studies on the children (anthropometric measurements and x-ray examinations of the left wrist and hand for bone developmentstudies ) ; special examinations of the skin with color photography of selected lesions; a special cancer detection survey; and an ophthalmological survey.

The family history did not yield satisfactory information, since the incidence of familial diseases including cancer was generally unknown by the. people. The history yielded some information on changes in weight, history of illness, and, in the case of women, menstrual, obstetric, and nursing history. {In the physical examination particular emphasis was placed on examination of the skin, node-bearing areas, head and neck, chest, breast, abdomen, and external genitalia. Pelvic examinations were carried out on all mature females, and vaginal and cervical smears for Papanicolaou examination were obtained.* Rectal examinations were carried out on all persons >40 years of age. This included, in the case of men, palpation of the prostate gland. Chest plates were not taken routinely but were obtained on about 30 adults >40 years of age (and on certain other cases where indicated)}.** Hematological data were obtained and were available for evaluation. In detection of possible leukemia (or preclinical evidence of incipient leukemia) the lymph nodes and spleen were carefully examined, and hematological data were taken including routine hemograms, percent basophils in a 4000 white cell count, and alkaline phosphatase examinations of the white blood cells on differential smears. *We wish to thank Dr. Genevieve Bader of Memorial CANCER DETECTION SURVEY In the cancer detection survey, procedures included an evaluation of the history, special phys- Sloan-Kettering Cancer Center, N.Y.C., for interpretation of the Papanicolaou smears. **We are grateful to Dr. Paul Lichtblau of Rockville Centre, L.IL, N.Y., for interpretation of the chest roentgenograms.
