Rae, waste produced in a city, the disposition of the liquid and solid radio- active waste resulting from reclamation lends itself readily to a sanitary engineering analysis. The analysis was performed by Dr. E. A. Pearson, Sanitary Engineering Consultant, and is reported herein. re St. Louis, Missouri,a typical inland industrial city, was selected for study as a hypothetical RW target area in order to illustrate the applicetion of the waste-disposal principles developed in the general ¢ The waste disposal problems encountered in the recovery of a contaminated area are closely dependent upon the reclamation procedures used. Therefore, a detailed analysis is presented of the logistics of recovery for St. Louis, based on the given characteristics of the agent and its dispersion, as a prerequisite to consideration of the disposal of radio- active waste produced during the recovery operations. (u) The land usage in St. Louis has been analyzed, and the tracts of the entire city classified into types corresponding to six typical districts. The area, population density, proportidénal roof and road coverage, and other pertinent characteristics of the area have been calculated. (u) Other factors affecting recovery planning include the strategic value of the facilities within the assumed target area, the radiation level distribution, the human and material resources available for recovery work, and the reccvery methods and their applicability. cussed and evaluated with reference to St. Louis. (u) TION (VU), These factors are dis- Each of the typical districts is analyzed in detail, and a composite representative area (one city block or more) is synthesized for each district. The detailed logistics of decontamination, by a variety of methods, of each representative area are calculated, and the results applied to 1-sq mi areas of their respective typical districts. Similarly, & detailed computation is made of the radiation levels throughout each representative area, and of the doses received by various reclamation workers cleaning up 1-sq mi areas of each typical district. (U) The results were applied, in turn, to five probable target areas within the city and the manpower and equipment requirements, the doses received, and the liquid and solid wastes produced are calculated for the rban waste olid average target area.
