ARMY SERVICE FORCES OAK RIDGE. TENNESSEE ~ 30 A p r i l. 1946~~~ List of Requests and EstirAated Needs for Redioisotopes. On 4April the undersighed sent you a n accumulated list of isotope requests m file in t'his office,At that time additional copies were not available.. We have now had photo stats made of the original and osing an extra copy for your file,. ,% - Attached tothe accumulated list of requests are copies of the imated needs for radioisotopes made by the M.I.T. Radioactivity Center he Washington University, St. Louis, fnote because they represent the estimated needs of two possible sers of radioelements.. In particular the estimates of the l!.I.T* ivity Center are of interest, because there i s included an estimate These two additions are the number of cyclotron hours per year that can,be saved if the iso - 8 s 'were to be supplied by apile. The K.1.T. estimates are based only . on the isotopes to be used a t M.I.T., and do not include the institutions they have been supplying.
