B. Medical Surveillance When the Rongelapese were returned to their homeisland, it was planned to inaugurate a program of continuing medical inspections. The Rongelapese would be examined once a month by a Marshallese practitioner and complete medical examination performed once a year by an American physician. Arrangements would be made for urine collections and analyses every three months for the first year and afterward on a yearly basis unless the findings indicate the necessity for more frequent analyses. A radio would be provided on Rongelap for communication with the Trust Territories Office on Ebeye (Kwajalein Atoll) where a plane would be available at all times for any emergency. A fully equipped dispensary would be provided on Rongelap and an experienced health aide (a Marshallese) would be present at all times. Before their return, the Marshallese would be given a complete medical examination, and immunized against smallpox, typhoid and tetanus. C. Environmental Contamination The degree of contamination on the home islands of the Rongelapese was considered
