ACP? & BBP: ¥DC Jamary 8, 195), Dr. Xarl Z. Morgan, Director Health Physics Division meae Rational Laboratory Oak Ridge, Tennessee BEST COPY AVAILABLE Dear Karl: iI.have your letter of January | and am most pleased that you will be present, and that you will discuss the basis of the NBS value for permissible body burden of strontium and your values for single exposures. We appreciate your suggestion that li. Farabee might discuss methods for estimating body burden of strontium. These methods are, of course, extremely important and the pecpls dealing with this phase of the probles will most certainly wish to talk with Mr. Farabee about such methods, Wednesday's meeting, however, will deal with the aspects of biological deposition and damage, and in the limited time available, I doubt very seriously that consideration could be given te bioassay methods, If Hr. Farabee is not particularly desirous of making the trip, therefore, I shall not ask him at this time. Looking forward to seeing you shortly = Yours very truly, US DOE ARCHIVES 326 U.S. ATOMIC ENERGY COMMISSION - Woe Ags salOf Collection Box Folder Walter D.
