MONTHLY STATUS AND PROGRESS REPORT Division of Biology and Medicine MONTH OF JULY, 1953 Weapons Test Activities fo en unaniberuca ccrson weve. Ba Dosimetry Conference--Operation UPSHOT/KNOTHOLE. A Dosimetry Conference was held on June 29 and 30 at the Na Medical at the Nevada Proving Grounds. Attendees included participating persomel from the AE Atomic Energy Project UCLA, ORNL, Lovelace Foundation, San AFSWP, USNRuL, NMRI, National Institutes of Health, Natio of Standards, and the FCDA, The purpose of the meeting was to interpret the vario and biclogicail measurements made in a variety of locations reach a unanimity of opinion on the probable neutron and g These data are to be used in the preparation of the Weapo Test The conference was successful except for measurements rays in the presence of significant levels of neutrons, Presumably, thermal and epithermal neutrons significantly the film darkening. Blast Conference--Operation UPSHOT/KNOTHOLE. A Blast Conference was held on duly 1 at Washington Head discuss observations made during the Civil Effects tests physical measurements of blast phenomena and effects carrjed cut in the Spring 1953 atomic test series at the Nevada Proving Attendees included participating personnel from the BHC, the Atomic Energy Project UCLA, USNRDL, NMRI, Sandia Corporation, Beilistics Research Laboretory, Aberdeen Proving Grounds ,f AFSWP, National Institutes of Health, Lovelace Foundation, and the FCDA. The purpose cf the meeting was to evaluate and interpret the physical responses of materials and structures and to redch agreement on basic blast data to be used in the preparation off the Civil Effects Test Group reports. Also, to compare the acceptdd measurements with thecretical predictions, scale-mcdel results, Jand the preliminary anelyses of biological damage. ee ee ee ee ST aOT ENERGY Dro. 25 aATOM EVIE - - 4] A ey Eibereggl { D.
