Scrap Disposal -°: Ideally, and if cost, time, and man-power were unlimited, disposal of scrap metal containing induced radioactivity in the very deep ocean outside the reef would be preferred. More realistically there are a number of factors to be considered: i. The location of channels in the reef through which boats loaded with scrap must pass is such that disposal outside the reef for scrap locations in the northern portion of the atoll will envolve a 25 to 30 mile round trip. . Disposal of metal, which will sink to the bottom, in water 175 to 200 feet deep inside the lagoon will make the scrap as unavailable to the natives’as in deeper water outside the reef. The lagoon floor in the area of test locations already contains a total quantity of serap in excess of that found on land. In fact, the added quagtity from the land areas would be a very small fraction of this total,: Disposal inside the reef will make scrap removal operations less weather and wind dependent since trips into open water and possibly into rough seas would not be needed. In this regard, operations inside the reef should be safer for boats and crews. With these factors in mind it is suggested that the foilowing guidelines be applied:
