instrumentation of lagoon raft stations. Samples will require transhipment to Elmer and courier flights to Army Chemical Center, M., after the events. 3.6 ——— Project Number: Sponsor: 2.6a Chemical, Physical and Radiochemical Analysis of Surface Contamination AFSWP Department of the Performing Agency: Navy Pr ject Officer: 3.6.1 Title: Dr. E, R. Tompkins U. S. Naval Radiological Defense laboratory Obiestiyve To dete:rmine the physical, chemical and radiochemical nature of residual contamination in order to assess the hazards associated with residual field radiation. To provide: information of use for the evaluation of the mechanism of distribution of bomb debris and thus improve the capability of scaling and prediction of residual contamimtion effects. To provide basic ormation essential to the study of decontamination and protection itechniques. 3.6.2 Procedure Radiochemical analysis-for.short-lived radioactive constituents of fall-out debris, early gross déeay measurements, and chemical analysis to determine the presence.and nature of transitory chemical states will be made in the forwaka/grea. Some of this work will be carried out in limited laboratoryspacB} Blaboard the light aircraft carrier (CVL) and further work carriedgut in mobile laboratory facilities on Elmer. Size distribution studies and most ofthe chemistry and radiochemistry will be carried .out at the U. S. Naval Radiological Defense Laboratory (USNRDL) on arrival of the samplesrollected under Project 2.5a. ul ci ae 3 3.6.3 Remarks The only support requirement for this project exeept for forward area laboratory facilities is the expeditious ‘return of Project 2.5a samples to Elmer and the USNRDL. 3.7 ProjectNumber: Sponsor: 2.6b Title: AFSWP Radiochemical“Anal: ‘sis of Surface Contaminat lan Performing agency: Department of the Navy Project Officer: Mr. R.
