It is recommended that the actual intensity existing today above the liquid be measured before recommendations are made on cutting through the concrete seal. A detailed statement of work on this problem follows. The calculations have been filed. In the study of the feasibility of cutting through the concrete seal on the center riser of the waste storage tank the radiation intensity that would be encountered is critical because director operator contact would be required. The question of the radiation intensity to be expected was approached from two standpoints: (a) a study of previous measurements of sludge level and activities in the storage tanks; and (b) direct calculation.
