decontardnation effectiveness, They may be of value however in locatinys high intensity areas in a contardinsated field where buildings or abrupt changes in surface contours may cause non-uniform settling of fallout. 6.2 RECOMMENDATIONS 1. The residual percentages given in the literature for the variovs decontamination operations should be reviewed in the light of the results of this operation, and reclamation planning of target complexes should be adjusted accordingly. 2. =%Im view of the added effectiveness of detergents for decontaminrtion; and the probability of serious water shortages on contaminated installations, the development of effective low cost detergent systems may be advisable. 3. The effect on construction material surfaces of the forms 4, The implications of increased dose wates in building 5. The influence of high intensity-level contamination on 6. Investigations concerned with the development of easily oN of contamination resulting from typical harbo: bottom materials should be determined on & comparison basis with the calcareous bottom materials found at CASTLE, interiors caused by wall contamination should be investigated, residual percentages following decontamination operations should be determined for comparison with relatively low-level contamination. removable protective coatings having weather resistant qualities should be accelerated. 7. #The effectiveness and practicability of exterior water sprays should be evaluated on fixed structures where immovability and surface irregularities may seriously reduce the effectiveness compared to test results with maneuvering ships. hh?
