® A TWX dated Lo 29 f-) to Bradbury summarizes Livermore's evaluation of the current status of Radchem sampling and analysis as applied to underground testing. | will quote tne last paragraph since It seems to have some useful thoughts: "In summary, we have satistac- tory results by core sampling on the shots above a kiloton and some doubtful results Sased on insufticient experience on the core sampling of shots in the neighborhood of 100 tons. Conversely the vacuum pipe technique is reliable for these latter shots, whereas proven state for the shots ebove a kilotcon. it is in an un- ( One should note as a restriction that our present ccarse sampling techniques desend on : plutonium as a tracer and that new Techniques willl have to be developed In case plutonium is absent." : A_30April memo from MacDougal! to Sradbury gives the shot priority lists arrived at by a group of lab personnel (MacDouggall, Hall, Mark, Agnew, Ogle, and Roy) tncluding a list for high yield devices, a list for smaller yleld devices, and also a list of those desired for one-point tests. 29 April [959, J-10 Report: Don Westervelt has completed a rrr report on the subject of air flourescense and detection of explosions B y In space, presumably addressed to the Vela Program at this time. cr He also has made calculations of energy deposition, time resolved flourescense brightness, and initial x-ray fireball brightness for an explosion at 105 kilometers, one of the proposed altitudes for operation Willow. | believe this is a series of high altitude tests being proposed by the military. The following will be some notes from monthly activity reports originated by 7.2 and begun covering the month of April 1959 fthrouth August 1959. Te This first report, in April, states "Morale remains excellent notwithstanding the uncertainties created by the proposed reorganization. Command emphsis on job participation and recreation activities effectively counter-act the effects of uncertainty." directed toward Reorganization planning was a coneentrated effort in all activities, maintaining high standards with a reduction in scope necessitated by the new proposed strength of less than 400. for H&N at this time.
