difficulties concerning stainless steel joints were encountered and will require a certain amount of refitting. From a gamma radiation standpoint the filtrate seens to carry over the majority of the activity and may build up to as much as 1/2 of the original activity. 80 mr/hr at contact. The first filtrate read approximately 60 to The metal will actually be made from the precipitate. Arrangements have been made with H-6 to measure in their extrapolation chamber approximately 500 grams on December 27, in order to give us the gamma emission at contact. 2. This work may continue in the future on a production line basis. High air counts up to three times tolerance were reported from the sludge room of the Waste Treatment Laboratory for the week of November 15 through 19. This was thought to be due to overfilling of the sludge cans and the sub- sequent cleanup. An attempt was made to rectify the overfilling and to wear respiratory protection during the cleanup. Some of the trouble was also found to be due to a filter queen running at 5.5 CFM instead of 4 CFM. The samples soon dropped to tolerance after the troubles had been rectified. An attempt was made to run hourly air samples; however, high humidity prevented successful operation. 3. Building. A bootie exchange station was also recommended, A mixture of 1% U~233 with U-235 was worked in Room 118, Sigma Surface contamination count data has been gathered for a report to H-5 to be included in their justification memo for possible future additional facilities required by CMR-6.
